Nanlite FC-300B & FC-500B COB Spotlight Review

A few weeks ago Nanlite announced its new FC-300B & FC-500B spotlights. They are LED Bi-color spotlights with a CCT range of 2700K-6500K, 12 built-in effects, and they feature a new look and design. Nanlite states that both fixtures offer high output and good performance, at an affordable price.

The FC-300B and 500B were designed as mid to entry-level lighting fixtures with easy-to-use controls.

Versatile COB lights in this form factor have become increasingly popular due to their Swiss army knife-style abilities, which enable them to be used for a variety of lighting scenarios. This is why we have seen so many of them being introduced over the last few years, and we continue to see more and more companies releasing similar style lights.

According to Nanlite, the quality of the FC-300B and FC-500B is on par with other Nanlite fixtures. Both fixtures have a claimed CRI of 96 and a TLCI of 98.

The Nanlite FC-300B and FC-500B look to be interesting lights given their relatively low cost and small size. So without further ado, let’s get on with the review.

Concept & Design

The concept behind all of these LED spot lights, whether they are daylight, bi-color, or full color, is to make a very flexible, fully-featured lighting source that won’t empty someone’s wallet. The only problem with this concept is that so many lighting companies are doing the exact same thing, that it is hard to make your product stand out.

• 

• 

The FC-300B and FC-500B sport a blue decorative frame and a wing-shaped top housing that according to Nanlite, is supposed to resemble a soaring eagle that symbolizes that in the world of creation, the sky is the only limit for the FC series. This is certainly an interesting take from the marketing department.

• 

• 

The design, at least in my opinion, isn’t a massive departure from other Nanite spotlights and the FC-300B and FC-500B look a little similar to a Prolycht Orion 300 FS.

• 

• 

Both lights have separate power supplies. The power supply for the FC-500B is considerably larger than the one for the FC-300B.

Build Quality

• 

• 

• 

• 

• 

The build quality of the Nanlite FC-300B & FC-500B is decent enough given their relatively low price tag and weight. The housing is reasonably robust but you shouldn’t expect the lights to have the same feel or quality as more expensive fixtures, because they don’t.

• 

• 

The power on/off button and the rest of the dials and buttons, at least in my opinion, could be a little better, but that is understandable given the low price point. They don’t have an overly tactile feel, but they do get the job done. They are almost identical to what you find on the FS-150B and FS-200B.

• 

• 

• 

• 

The yoke frame locks down securely when tightened, and the lever that you use to do that is robustly made.

The locking mechanism for where you attach the yoke frame to a light stand works well.

• 

• 

The separate power supplies for both fixtures are solidly constructed and well made.

• 

• 

• 

They both have a V-mount adapter so you can mount them onto an optional lightstand clamp. They also have a lanyard that you can use to attach to a lightstand.

The lights come with a limited 2 Year Warranty which can be extended to 3 years by registering online.

COB Design

Lots of LED lights on the market, including the Nanlite FC-300B and FC-500B are using COB technology. COB stands for “Chip On Board” where multiple LED chips are packaged together as one lighting module. The advantage of COB LEDs being multi-chip packaged is that the light-emitting area of a COB LED can contain many times more light sources in the same area that standard LEDs could occupy. This results in a greatly increased lumen output per square inch.

• 

• 

Both fixtures feature a decent-sized fan that is on the underside of the lights.

The biggest problem with COB LED lights is that unless you diffuse them they are very bright to look at and unsuitable for directly lighting talent.

Weight & Size

• 

• 

The Nanlite FC-300B and FC-500B are reasonably compact, however, as I previously mentioned, they do have quite large power supplies.

The FC-300B weighs just 5.73 lb / 2.6 kg, and the FC-500B tips the scales at 6.97 lb / 3.16 kg.

• 

• 

The power supply for the FC-300B weighs 2.43 lb / 1.1 kg and the power supply for the FC-500B weighs 4.94 lb / 2.24 kg.

• 

• 

The FC-300B in its included case tips the scales at 5.8kg / 12.78 lb. This makes it a nice lightweight solution if you are traveling.

• 

• 

The FC-500B in its included case weighs 8.1kg / 17.85 lb.

How does the weight of the FC-300B compare to some other fixtures that could be considered competition? Below you can see.

	WEIGHT
Nanlite FC-300B	3.7 kg / 8.16 lb
Aputure LS 300x	11.4 kg / 25.13 lb
Godox SL300IIIBI	3.59 kg / 7.91 lb
GVM Pro SD400B	7.6 kg / 16.7 lb
Kelvin Epos 300	8.2 kg / 18.07 lb
Prolycht Orion 300 FS	6.9 kg / 15.21 lb
amaran 300c RGB LED Monolight	3.52 kg / 7.76 lb
Godox SZ300R Zoom RGB LED Spotlight	3.2 kg / 7.1 lb
Lupo Movielight 300 Full Color PRO	5 kg / 11 lb

How does the weight of the FC-500B compare to some other fixtures that could be considered competition? Below you can see.

	TOTAL WEIGHT
Nanlite FC-500B	5.4 kg / 11.91 lb
Maxima 6 GaN	4.6 kg / 10.14 lb (Fixture with Yoke)
ARRI Orbiter	11.7 kg / 25.79 lb (without Yoke)
Prolycht Orion 675 FS	11.1 kg / 24.5 lb (Fixture with Yoke)
Aputure LS 600x Pro	10.44 kg / 23.01 lb (with yoke and power supply)
Godox Knowled M600DBI	8.48 kg / 18.69 lb (with yoke and power supply)
Nanlite Forza 720B	9 kg / 19.84 lb (with yoke and power supply)
Kelvin Epos 600	12.18 kg / 26.85 lb (with yoke and power supply)
FotodioX Pro Warrior 600X	10.61 kg / 23.4 lb (with yoke and power supply)
CAME-TV Tioga Series 660W Bi-Color	10.49 kg / 23.12 lb (with yoke and power supply)

The nice aspect about this low weight is that you can use both these lights with a reasonably lightweight and compact light stand. By having a separate power supply, Nanlite has made this possible.

CCT range

• 

• 

Both lights have a CCT range of 2700K to 6500K. This is a decent enough range and it will suit most people’s needs.

Beam Angle

The beam angle of the fixtures, when used open face, is 120°.

If you use the lights with their included reflector it is 55°.

The included reflectors are the same that you get with most Nanlite Bowens mount fixtures.

Mounting

The Nanlite FC-300B and FC-500B both come with a traditional two-sided yoke frame.

While these work reasonably well, there isn’t a lot of clearance and the power cable will end up hitting the yoke frame if you try and tilt the light up too much.

As I mentioned previously, the yoke frame locks down tightly.

Power Draw

The power draw of the FC-300B is 350W, and with the FC-500B, it is 520W.

Unfortunately, Nanite doesn’t give you many options when it comes to powering the fixtures. There is no way of running it via a camera battery like you can from so many competing fixtures. The only way you can run the fixtures remotely is via the 48V DC PowerCon input.

In the kit, you just get an AC power cable. Yes, I know these are more aimed at indoor studio use, but given their relatively low weight it would have been nice to have seen a camera battery powering option, even if this was an optional extra. A lot of people looking at lights want versatility and the ability to use their fixtures in a variety of different ways and in different environments.

Mount

• 

• 

Like most COB spotlights, the Nanlite FC-300B and FC-500B utilize a Bowens S mount. This allows you to use readily available lighting modifiers and accessories that you may already own.

Like every Bowens S mount that doesn’t feature a locking mechanism, light modifiers will wobble around on the mount.

Controls & Menu System

The rear LCD screen on the light looks similar to what you would find on most of the Nanlite products. Although it is fairly basic, it does show you key information about the light’s operating modes, brightness, CCT, etc.

As I say in every lighting review, with a good light, you shouldn’t have to read a manual to work out how to operate it. You should be able to turn it on and use it straight away. With the FC-300B and FC-500B, it is easy to make changes to the CCT and brightness. The Menu is also very straightforward and easy to navigate.

• 

• 

• 

• 

• 

In the menu, you can adjust quite a few settings, such as the DMX, fan, etc. The menu is pretty intuitive.

As well as being able to adjust certain parameters and modes on the light itself, you can also use the NANLINK Bluetooth app. Additionally, 2.4GHz provides control through the separately-available WS-TB-1 transmitter box for more elaborate setups, or with hardware remotes like the NANLINK WS-RC-C2. DMX/RDM control is also supported for advanced users.

Operating Modes

The lights have the following lighting modes that you can access from the fixture:

• CCT
• EFFECT

The lights also feature a Maximum Output Mode and Constant Output Mode and Nanlite claims that there isn’t any CCT shift from 2700K-6500K in either mode.

No +/- Green adjustment

The fixtures don’t include +/- Green adjustment so you can’t correct any tint.

EFFECTS

The EFFECT mode lets you recreate a wide range of lighting effects that can be handy for certain scenarios. The effects include:

All the effects modes can be individually adjusted, and you change the Speed and Cycle.

Bluetooth App

• 

• 

• 

• 

• 

The lights can be controlled via Bluetooth using the NANLINK App. It is relatively easy to connect up a light and get started. All you need to do is tap on add a fixture and then choose how you want to connect.

• 

• 

For this example I chose Bluetooth and the app will search for available Nanlite fixtures.

Once you select the fixture you want to add, it takes about 5-10 seconds for the app to configure everything.

Once the fixture is set up you can see that it has been added to the scene page.

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

There is a range of parameters that you can adjust using the app, including changing the output, CCT, turning the fan on/off, saving presets, and switching between constant and maximum output modes.

The app is straightforward and reasonably easy to use, however, they haven’t made it as intuitive or visually appealing as some other companies’ lighting control apps. This is something I would like to see Nanlite work on.

The only other downside when using the app is that when you make changes they don’t happen instantaneously, there is a slight delay.

How do they stay cool?

• 

• 

COB lights get very hot, and keeping them cool is not an easy task. The FC-300B and 500B, as I mentioned earlier in the review, do utilize a fan.

In the menu settings for the FC-300B and FC-500B, you have the choice of setting the fan to the following modes:

• SMART
• FULL
• LOW
• OFF

• 

• 

You can also change the fan settings using the NANLINK app. The trouble when doing this with the app, is that the intensity slider will still show 100% even if you change the fan setting to a mode where 100% isn’t possible. This is where I think NANLITE needs to pay more attention to small details. Little quirks like this could easily be addressed by updating the app, but unfortunately, a lot of lighting companies release apps, and then very rarely ever update them.

The fan in the FC-300B is fairly quiet even when the light is operating at 100% output in its Max Output mode. If you do set the fan speed to High Speed, you may notice it if you are in a very quiet room and have the light close to where audio is being captured.

On the FC-500B, the fan is louder than that of the FC-300B. I would recommend that you don’t put the FC-500B too close to an audio recording source. It isn’t like the fan is really loud in its Smart setting, but you might hear it in a quiet room if it was only a meter or so away from where audio was being recorded. The High Speed fan mode could potentially be an issue when recording audio, but again, it depends on how close the light is to where audio is being recorded and how quiet the room is.

Photometrics

So now let’s get to the photometric results. I always test lights in this way so that I get a reference to how they compare to other fixtures. Results only tell part of the story and should never be used alone to judge a light. I have found from extensive testing over the years that certain lights that have good photometric results don’t always look good, and lights that have worse photometric scores can sometimes look better than their results indicate.

You can’t judge a light from one set of photometric results. You have to look at all of the different results to be able to come to a conclusion. You wouldn’t read one chapter of a book and think you know the whole story, so don’t look at one set of results for a light and think you can make a conclusion because you can’t.

Different lights can also look different depending on what camera you happen to be using.

Output & Color Temperature Accuracy

I tested the Nanlite FC-300B and 500B at a variety of CCT settings with a Sekonic C-800 Spectrometer to find out how much output the light had and how accurate the Kelvin color temperature reproduction was. All readings are taken at a distance of 1m (3.28ft) in a controlled environment. The readings were also taken directly from the lighting source. In the case of using the lights with their Reflector, the readings were taken from the end of those attachments.

• 

• 

• 

Above are the claimed photometric data that Nanlite lists for the FC-300B.

• 

• 

• 

Above are the claimed photometric data that Nanlite lists for the FC-500B.

Ok, so let’s find out if those figures are correct.

Open Face 5600K (max. output mode)

Nanlite FC-300B 5600K (open face)

Above you can see the FC-300B recorded an output of 9530 lx (885 fc) when set at 5600K and used open face. Nanlite lists a figure of 11,210 lx, so the result I got was a lot less than their claimed figure.

The light recorded a CCT reading of 5735K which was ok, but more than 130K off being correct.

Nanlite FC-500B 5600K (open face)

Above you can see the FC-500B recorded an output of 22,100 lx (2060 fc) when set at 5600K and used open face. Nanlite lists a figure of 21,110 lx, so the result I got was slightly higher than their claimed figure.

The light recorded a CCT reading of 5679K which was a pretty good result.

Open Face 3200K (max. output mode)

Nanlite FC-300B 3200K (open face)

Above you can see the output when it was set at 3200K in the open face configuration was 9820 lx (912 fc), which was just 3.04% higher than the 9530 lx it produced at 5600K. Nanlite lists a figure of 10,617 lx, so the result I got was not too far away from their claimed figure.

As far as CCT accuracy goes, it recorded an extremely accurate reading of 3231K.

Nanlite FC-500B 3200K (open face)

Above you can see the output when it was set at 3200K in the open face configuration was 17,600 lx (1630 fc), which was 20.36% less than the 22,100 lx it produced at 5600K. Nanlite lists a figure of 17,670 lx, so the result I got was very similar to their claimed figure.

As far as CCT accuracy goes, it recorded a decent reading of 3096K.

Ok, so let’s now look at how much output both lights had at various CCT settings when used open face in their max. output modes.

FC-300B Open Face (max output mode)

	OUTPUT	CCT READING
2700K	7520 lx	2718K
3200K	9820 lx	3231K
4500K	11,200 lx	4640K
5600K	9530 lx	5735K
6500K	8440 lx	6505K

The fixture has the most amount of output at 4500K.

As you can see, in the max. output mode the output varies by 32.85% across the CCT range. The light was no more than 140K off being correct at any of its CCT settings. It was the most accurate when used at 6500K.

FC-500B Open Face (max output mode)

	OUTPUT	CCT READING
2700K	15,800 lx	2761K
3200K	17,600 lx	3090K
4500K	21,400 lx	4538K
5600K	22,100 lx	5679K
6500K	20,800 lx	6551K

The fixture has the most amount of output at 5600K.

As you can see, in the max. output mode the output varies by 39.87% across the CCT range. The light was no more than 179K off being correct at any of its CCT settings. It was the most accurate when used at 4500K.

Reflector 5600K (max. output mode)

So, now let’s see how much output the lights have when used with their 55° reflector.

FC-300B 5600K (Reflector 55°)

Above you can see the light’s output when it was set at 5600K with the reflector was 29,900 lx (2780 fc). This was 213.74% more than the 9530 lx it produced at 5600K when used open face. It is important to note that this measurement was made from the end of the reflector. This is a decent amount of output from a fixture that draws 350W.

As far as CCT accuracy goes, it recorded an okay reading of 5746K. The CCT accuracy when using the reflector was very similar to when the light is used open face. It is nice to know that when using the reflector the light’s CCT won’t change by any real noticeable difference.

Nanlite FC-500B 5600K (Reflector 55°)

Above you can see the light’s output when it was set at 5600K with the reflector was 53,300 lx (4950 fc). This was 141.17% more than the 22,100 lx it produced at 5600K when used open face. It is important to note that this measurement was made from the end of the reflector. This is a lot of output from a fixture that draws 500W.

As far as CCT accuracy goes, it recorded a very accurate reading of 5756K. The CCT accuracy when using the reflector was not as good as when the light was used open face.

3200K Reflector (max. output mode)

Nanlite FC-300B 3200K (Reflector 55°)

Above you can see the output when it was set at 3200K with the standard reflector was 30,000 lx (2790 fc), which was just 0.33% more than what it output at 5600K using the reflector.

As far as CCT accuracy goes, it recorded an exceptionally good reading of 3272K which was a very good score and slightly better than the result it obtained when used open face.

Nanlite FC-500B 3200K (Reflector 55°)

Above you can see the output when it was set at 3200K with the standard reflector was 41,700 lx (3880 fc), which was 21.76% less than what it output at 5600K using the reflector.

As far as CCT accuracy goes, it recorded an exceptionally good reading of 3119K which was a very good score and very similar to what it recorded when used open faced.

Ok, so let’s now look at how much output both lights had at various CCT settings when used with their 55° reflector in their max. output modes.

FC-300B Reflector 55° (max output mode)

	OUTPUT	CCT READING
2700K	23,000 lx	2749K
3200K	30,000 lx	3272K
4500K	34,600 lx	4670K
5600K	29,900 lx	5746K
6500K	26,100 lx	6467K

The fixture has the most amount of output at 4500K.

As you can see, in the max. output mode the output varies by 33.52% across the CCT range. The light was no more than 170K off being correct at any of its CCT settings. It was the most accurate when used at 6500K.

FC-500B Reflector 55° (max output mode)

	OUTPUT	CCT READING
2700K	38,100 lx	2797K
3200K	41,700 lx	3119K
4500K	50,700 lx	4592K
5600K	53,300 lx	5756K
6500K	51,500 lx	6500K

The fixture has the most amount of output at 5600K.

As you can see, in the max. output mode the output varies by 28.51% across the CCT range. The light was no more than 156K off being correct at any of its CCT settings. It was the most accurate when used at 6500K.

How does the output compare against the competition?

Below you can see how the Nanlite FC-300B and FC-500B compare to some of the competitors when it comes to output when all of the lights are using their included reflectors.

Nanlite FC-300B

5600K

	Output at 5600K	CCT (K)
Nanlite FC-300B	29,900 lx* (55° reflector)	5746K

amaran 300c RGB	26,580 lx** (65° reflector)	NA
Lupo Movielight 300 Full Color PRO	28,600 lx* (55° reflector)	5779K
Aputure Light Storm 300x	17,500 lx* (hyper reflector)	5295K

*Independently tested

**Manufacturers claims

As you can see, the Nanlite FC-300B had more output than any of these other lights, however, it does draw 350W. Its CCT reading at 5600K was pretty decent, but not as good as the Kelvin Epos 300 or Prolycht Orion 300 FS.

3200K

	Output at 3200K	CCT (K)
Nanlite FC-300B	30,000 lx* (55° reflector)	3272K
Kelvin Epos 300	18,500 lx* (55° reflector)	3265K
Prolycht Orion 300 FS	25,000 lx* (standard reflector)	3148K
amaran 300c RGB	21,390 lx** (65° reflector)	NA
Lupo Movielight 300 Full Color PRO	28,200 lx* (55° reflector)	3139K
Aputure Light Storm 300x	15,100 lx* (hyper reflector)	3144K

*Independently tested

**Manufacturers claims

As you can see, the Nanlite FC-300B had more output than any of these other lights. Its CCT reading at 3200K was pretty good, but not quite as good as the other competing fixtures.

Nanlite FC-500B

5600K

	OUTPUT at 5600K	CCT
Nanlite FC-500B 55° Reflector	53,300 lx	5756K
Maxima 6 GaN Boost mode 70° Reflector	65,700 lx	5507K
Maxima 6 GaN Regular mode 70° Reflector	57,600 lx	5506K
Aputure LightStorm LS 600d II Pro 55° Hyper Reflector	97,100 lx	5728K
Aputure LightStorm LS 600c Pro 55° Hyper Reflector	49,000 lx	5617K
Prolycht Orion 675 FS 55° Reflector	55,700 lx	5515K
Nanlite Forza 720 55° Reflector	124,000 lx*	NA
Nantlite Forza 720B 55° Reflector	73,000 lx	5397K

*Not independently tested (manufacturer claims)

As you can see, the Nanlite FC-500B had almost the same amount of output as the Prolycht Orion 675 FS despite having a lot lower power draw. Its CCT reading at 5600K was not as good as most of the other competing fixtures.

3200K

	Output at 3200K	CCT
Nanlite FC-500B	41,700 lx (55° Reflector)	3119K
Aputure LS 600c Pro	37,300 lx (Hyper reflector 62°)	3209K
Prolycht Orion 675 FS	47,700 lx (wide reflector 55°)	3230K
Nantlite Forza 720B	58,900 lx (55° Reflector)	3148K

As you can see, the Nanlite FC-500B has a decent amount of output considering it has a lot lower lot power draw. Its CCT reading at 3200K was not quite as good as most of the other competing fixtures.

Again, I need to stress that these are not apples-to-apples comparisons because of the different power draws and beam angles.

Constant Output Mode

Let’s now look at how much output the FC-300B and FC-500B have when they are used in their constant output mode. In theory, the output should be almost identical in all CCT settings when the lights are used in this mode.

Summary of results FC-300B (Reflector)

SETTING	OUTPUT	CCT READING
2700K	22,500 lx	2745K
3200K	22,100 lx	3264K
4500K	21,800 lx	4640K
5600K	22,100 lx	5706K
6500K	22,700 lx	6454K

These results show me that the light’s output varies by only 3.96% across the CCT range when used in its constant output mode.

Summary of results FC-500B (Reflector)

SETTING	OUTPUT	CCT READING
2700K	35,900 lx	2799K
3200K	33,500 lx	3140K
4500K	33,300 lx	4553K
5600K	35,100 lx	5568K
6500K	36,900 lx	6459K

These results show me that the light’s output varies by 9.75% across the CCT range when used in its constant output mode.

Nanlite FC-500B with DoPChoice Octa 3 Softbox

Let’s now see how much output the FC-500C has when used in conjunction with a DoPChoice Octa 3 softbox at 5600K.

Above you can see the output when it was set at 5600K and used with the DoPChoice Octa 3 softbox was 9510 lx (884 fc). This is a good amount of output.

As far as CCT accuracy goes, it recorded an exceptionally good reading of 5529K.

CCT consistency & linear output when dimming the lights

Now, what you should always do when testing lights is to see if the CCT remains consistent when dimming the light. Just because you set a light at say 5600K, that doesn’t mean that the CCT will remain stable as you start dimming the fixture down. I also wanted to see how linear the dimming curve was.

I decided to do a series of tests at 100%/75%/50%/25%10% to see if the Kelvin color temperature being recorded changed. This was done at a distance of 1m using a Sekonic C-800. These tests were done at 5600K with the reflector.

Nanlite FC-300B

CCT READING	OUTPUT	INTENSITY %
5746K	29,900 lx	100
5729K	21,700 lx	75
5731K	14,300 lx	50
5719K	7,340 lx	25
5734K	3,100 lx	10

The Nanlite FC-300B is excellent at maintaining CCT consistency as you start dimming the fixture. My testing showed that the CCT varied by only 27K.

As far as how linear the output is when you start dimming the light, at 50% output it had 52.17% less output than when used at 100%. At 25% it had 75.45% less output than when used at 100%. At 10% output, it had 89.63% less output than when used at 100%. This shows me that the light’s dimming curve is very linear.

Nanlite FC-500B

CCT READING	OUTPUT	INTENSITY %
5756K	53,300 lx	100
5635K	38,800 lx	75
5594K	25,400 lx	50
5585K	12,900 lx	25
5562K	5,650 lx	10

The Nanlite FC-500B wasn’t as good as the FC-300B at maintaining CCT consistency as you start dimming the fixture. My testing showed that the CCT varied by 194K.

As far as how linear the output is when you start dimming the light, at 50% output it had 52.34% less output than when used at 100%. At 25% it had 75.79% less output than when used at 100%. At 10% output, it had 89.39% less output than when used at 100%. This shows me that the light’s dimming curve is extremely linear.

Output in various fan modes

As you can adjust the fan settings, let’s see how the output gets affected.

Nanlite FC-300B 5600K Reflector

	OUTPUT
Smart	29,900 lx
Low	14,400 lx
Off	4,560 lx

What this tells me is that when you use the FC-300B in the Low fan setting the output gets reduced by 51.83%. When you turn the fan Off the output gets reduced by 84.74%.

Nanlite FC-500B 5600K Reflector

	OUTPUT
Smart	53,300 lx
Low	25,500 lx
Off	4,750 lx

What this tells me is that when you use the FC-300B in the Low fan setting the output gets reduced by 52.15%. When you turn the fan Off the output gets reduced by 91.08%.

Color Rendering

So now that we have seen how much output the Nanlite FC-300B and FC-500B produce, how do they perform when it comes to replicating accurate colors?

Nanlite FC-300B 5600K (Reflector)

Above you can see that when the FC-300B was set at 5600K using the standard reflector it recorded an average CRI (R1-R8) of 98.1 and an extended CRI (R1-R15) of 96.7. For replicating accurate skin tones it recorded 95.5 for R9 (red), 99.4 for R13 (closest to caucasian skin tones), and 97.9 for R15 (closest to Asian skin tones). These are excellent results, although the light struggles to produce R12 (Blue) with a score of just 81.9

Nanlite FC-500B 5600K (Reflector)

Above you can see that when the FC-500B was set at 5600K using the standard reflector it recorded an average CRI (R1-R8) of 97.3 and an extended CRI (R1-R15) of 95.49. For replicating accurate skin tones it recorded 90.8 for R9 (red), 98.6 for R13 (closest to caucasian skin tones), and 97.3 for R15 (closest to Asian skin tones). These are excellent results, although the light struggles to produce R12 (Blue) with a score of just 78.9.

	CRI	EXTENDED CRI	R9	R13	R15
FC-300B	98.1	96.70	95.5	99.4	97.9
FC-500B	97.3	95.49	90.8	98.6	97.3
Forza 720B	98.6	97.04	92.7	99.3	97.2

As a color rendering accuracy comparison, above you can see how the FC-300B and FC-500B compare against Nanlite’s own Forza 720B. the color rendering scores are very close to that of one of Nanlite’s much more expensive fixtures.

The FC-300B, when set at 5600K, recorded a TLCI score of 99.

The FC-500B, when set at 5600K, also recorded a TLCI score of 99.

Nanlite FC-300B 3200K (Reflector)

Above you can see the scores for when the light was used at 3200K. It recorded an average CRI (R1-R8) of 95.7 and an extended CRI (R1-R15) of 94.32. For replicating accurate skin tones it recorded 92.4 for R9 (red), 93.8 for R13 (closest to caucasian skin tones), and 94.4 for R15 (closest to Asian skin tones). These were good results, but not quite as good as when the light was used at 5600K. Only R12 (Blue) was marginally below 90.

Nanlite FC-5000B 3200K (Reflector)

Above you can see the scores for when the light was used at 3200K. It recorded an average CRI (R1-R8) of 96.5 and an extended CRI (R1-R15) of 95.58. For replicating accurate skin tones it recorded 98.2 for R9 (red), 95.1 for R13 (closest to caucasian skin tones), and 96.7 for R15 (closest to Asian skin tones). These were good results, but not quite as good as when the light was used at 5600K. Only R12 (Blue) was under 90.

	CRI	EXTENDED CRI	R9	R13	R15
FC-300B	95.7	94.32	92.4	93.8	94.4
FC-500B	96.5	95.58	98.2	95.1	96.7
Forza 720B	96.5	96.22	97.4	95.6	97.4

As a color rendering accuracy comparison, above you can see how the FC-300B and FC-500B compare against the Nanlite Forza 720B. I just wanted to do this comparison to show you how the color rendering accuracy compared between more affordable options and one of Nanlite’s more expensive fixtures.

The FC-300B, when set at 3200K, recorded a TLCI score of 98.

The FC-500B, when set at 3200K, recorded a TLCI score of 98.

CC Index & ⊿uv

The CC Index displays the CC correction value and whether any magenta or green need to be added or subtracted. 1 CC corresponds to 035 Kodak CC values or 1/8 Rosco filter values. Any reading less than +1.00 or -1.00 and you’re probably not going to need to make any kind of adjustment. The ⊿uv is the value to show how much this light is away from being an ideal light source (black body radiation = incandescent lamp). As with the CC Index you want this number to theoretically be zero. Kelvin is not a linear value, so we need to convert from Kelvin to MK-1 to compare the values of color temperature. To calculate from Kelvin to Mired is MK-1= 1*1000000/Kelvin. While this may sound confusing, it is the only way of measuring if the Kelvin shift is significant enough to warrant having to use a filter for correction. Below are the results for the Nanlite FC-300B and 500B:

Nanlite FC-300B Kelvin Vs MK-1

	Kelvin	Difference in K	MK-1	Difference in MK-1
SET VALUE	2700K	0	370.37	0
ACTUAL READING	2749K	49	363.76	6.61 MK-1
SET VALUE	3200K	0	312.5	0
ACTUAL READING	3272K	72	305.62	6.88 MK-1
SET VALUE	4500K	0	222.22	0
ACTUAL READING	4670K	170	214.13	8.09 MK-1
SET VALUE	5600K	0	178.57	0
ACTUAL READING	5746K	54	174.03	4.54 MK-1
SET VALUE	6500K	0	153.84	0
ACTUAL READING	6467K	33	154.63	-0.79 MK-1

These figures might look confusing, but what they tell me is that the light is reasonably CCT between 2700K and 4500K. Any MK-1 score that is under -9/9 means you wouldn’t have to use any color correction gels. The MK-1 scores for this light were very good at 5600K and especially 6500K. Any MK-1 score that is under -6/6 is a very good result.

Nanlite FC-500B Kelvin Vs MK-1

	Kelvin	Difference in K	MK-1	Difference in MK-1
SET VALUE	2700K	0	370.37	0
ACTUAL READING	2797K	97	357.52	12.85 MK-1
SET VALUE	3200K	0	312.5	0
ACTUAL READING	3119K	81	320.61	-8.11 MK-1
SET VALUE	4500K	0	222.22	0
ACTUAL READING	4592K	92	217.77	4.45 MK-1
SET VALUE	5600K	0	178.57	0
ACTUAL READING	5756K	156	173.73	4.84 MK-1
SET VALUE	6500K	0	153.84	0
ACTUAL READING	6500K	0	153.84	0 MK-1

These figures might look confusing, but what it tells me is that the light is very CCT accurate at 4500K and above. In fact, at 6500K it had a perfect score, which I have never seen before. Unfortunately, at 2700K the score was pretty bad. Any MK-1 score that is under -9/9 means you wouldn’t have to use any color correction gels. The MK-1 scores for this light were very good, but not consistent. Any MK-1 score that is under -6/6 is a very good result.

Nanlite FC-3000B CC INDEX & ⊿uv

	CC INDEX	⊿uv
2700K	0	-0.0004
3200K	0.3G	-0.0038
4500K	0.1G	-0.0023
5600K	0.1M	0.0028
6500K	0.2M	0.0053

These were decent results across the board, but the ⊿uv scores could have been better for 3200K and 6500K.

Nanlite FC-500B CC INDEX & ⊿uv

	CC INDEX	⊿uv
2700K	0.0	-0.0004
3200K	0.2G	-0.0028
4500K	0.2G	-0.0024
5600K	0.1M	0.0025
6500K	0.2M	0.0049

Again, these were very good results across the board.

TM-30

TM-30 is a relatively new color rendering standard that was developed to deal with the limitations of CRI. TM-30 looks at 99 individual colors. These 99 colors are categorized into seven groups: nature, skin color, textiles, paints, plastics, printed material, and color systems.

TM-30 scores go from 0 – 100. The higher the score, the more accurate a light is at producing colors. Any TM-30 Rf score in the ’90s is considered to be good. What is interesting and something that you need to be very aware of is that two separate light sources with the exact same CRI scores can render colors very differently. A light with a high CRI rating could have a low TM-30 score. Conversely, a light with a good TM-30 score could have a bad CRI score.

Now, there are two measurements associated with TM-30, Rf and Rg.

Rf (Color Fidelity)
Rg (Color Gamut)

With Rf value, ideally, you want a score in the 90’s.

With Rg value, a score below 100 indicates that the light source renders colors with less saturation than the reference source. So ideally you want this score to be above 100.

Nanlite FC-300B

Above you can see the scores for the FC-300B at various Kelvin color temperatures. Below I have listed the figures as well.

Here are the results:

	Rf	Rg
2700K	96	101
3200K	95	103
4500K	95	103
5600K	95	101
6500K	94	99

The TM-30 scores are very good and it shows me that the light is pretty consistent at replicating accurate colors with full saturation. The consistency of their scores was good.

Nanlite FC-500B

3200K	95	102
4500K	95	102

6500K	93	99

The TM-30 scores are all excellent and it shows me that the light is very consistent at replicating accurate colors with full saturation. The consistency of the scores was very impressive.

SSI

SSI (Spectral Similarity Index) was developed by the Sci-Tech Council of the Academy. SSI gives me the ability to set any light as a standard, or use predefined standards (such as CIE D55), and then give other lights an SSI score based on how well they will match standards such as CIE D55. This way I can measure spectral response and compare it directly against an ideal light source. This is actually a much better test than recording CRI scores.

Nanlite FC-300B 3200K

In this graph, the red bars indicate a perfect Planck 3200K source. The gold bars indicate a perfect 3200K Tungsten source. This lets us compare how close to a perfect 3200K lighting source the FC-300B is. Any SSI score in the high 70’s, low ’80s is very good for a 3200K LED light. The results for the FC-300B were reasonably good when used at 3200K. As you can see, LED lights have a hard time replicating colors below about 450nm.

Nanlite FC-500B 3200K

In this graph, the red bars indicate a perfect Planck 3200K source. The gold bars indicate a perfect 3200K Tungsten source. This lets us compare how close to a perfect 3200K lighting source the FC-500B is. Any SSI score in the high 70’s, low ’80s is very good for a 3200K LED light. The results for the FC-500B were reasonably good when used at 3200K. As you can see, LED lights have a hard time replicating colors below about 450nm.

Nanlite FC-300 5600K

In the graph above the gold bars indicate a perfect CIE D55 source. The red bars indicate a perfect CIE D 5600K source. This lets us compare how close to a perfect 5600K lighting source the FC-300B is. A score in the low 70’s is typical for a 5600K LED source.

Nanlite FC-500B 5600K

In this graph, the red bars indicate a perfect Planck 3200K source. The gold bars indicate a perfect 3200K Tungsten source. This lets us compare how close to a perfect 3200K lighting source the FC-500B is. Any SSI score in the high 70’s, low ’80s is very good for a 3200K LED light.

The main reason we want to record SSI scores is so we can see how well they match with other lights. As an example, I wanted to see how well the FC-300B and FC-500B matched the ARRI Orbiter and Prolycht Orion 675 FS. Below you can see the results.

FC-300B 5600K

As you can see neither lights are a perfect match, but they are a decent enough match. You could easily use all three of these lights together without any issues if you did a bit of tweaking.

FC-500B 5600K

Just like with the FC-300B, the FC-500B isn’t a perfect match with the ARRI Orbiter and Prolycht Orion 675 FS, however, you could easily use all three of these lights together without any big issues.

Ok, so now we have seen how well the FC-300B and FC-500B match other lights, but do they match each other? Well, let’s find out. First, I wanted to see how well the FC-300B matched the FC-500B when both lights were using their reflectors and also how well the FC-300B matched itself when used Open Faced.

FC-300B 3200K

As you can see, the FC-300B was almost an identical match when used with or without its reflector. It was also a very, very close match to the FC-500B. This clearly shows me that both the FC-300B and FC-500B can be used together and they will match.

Next, I wanted to see how well the FC-500B matched the FC-300B when both lights were using their reflectors and also how well the FC-500B matched itself when used Open Faced.

FC-500B 3200K

As you can see, the FC-500B was almost an identical match when used with or without its reflector. It was also a reasonably close match to the FC-300B.

Ok, so now let’s do that exact same test again, but this time at 5600K.

FC-300B 5600K

As you can see, the FC-300B was almost an identical match when used with or without its reflector. It was also almost a perfect match to the FC-500B. This clearly shows me that both the FC-300B and FC-500B can be used together and they will match.

Next, I wanted to see how well the FC-500B matched the FC-300B when both lights were using their reflectors and also how well the FC-500B matched itself when used Open Faced.

FC-500B 5600K

As you can see, the FC-500B was almost an identical match when used with or without its reflector. It was also almost a perfect match to the FC-300B.

SSI tests are a great way of telling you what lights you own or use will work well together.

Spectral Distribution

Nanlite FC-300B 5600K

Above you can see the spectral distribution of the FC-300B when it is set at 5600K. The spectral distribution isn’t overly full, but it is fairly consistent with no spikes where you wouldn’t expect to see them.

Nanlite FC-500B 5600K

Above you can see the spectral distribution of the FC-500B when it is set at 5600K. The spectral distribution isn’t overly full, and it was almost identical to the FC-300B.

As a comparison, above you can see the spectral distribution of the Nanlite Forza 720B. It is considerably fuller than both the FC-300B and FC-500B.

Nanlite FC-300B 3200K

Above you can see the spectral distribution of the FC-300B when it is set at 3200K.

Nanlite FC-500B 3200K

Above you can see the spectral distribution of the FC-500B when it is set at 3200K.

As a comparison, above you can see the spectral distribution for the Nanlite Forza 720B.

All three lights had very similar spectral responses when used at 3200K.

Real-World Performance & Quality of Light

As I always say, photometric scores only tell you part of the story. So let’s how the FC-300B and FC-500B perform in the real world.

The photometric results can only give me scientific data and it is much more important for me to see how the lights look and perform.

The FC-300B and FC-500B are both capable of producing great results and most importantly they are relatively easy to use and quick to set up.

• 

• 

The reflectors do have a slight hot spot, but they don’t produce any color fringing on the edges of the beam.

• 

• 

Above you can see the difference in the type of shadows they create when used open face and with their reflector. When used open face you will get clean shadows. If you use the reflector then the shadows won’t have defined outlines.

• 

• 

As a further test, above you can see what the shadows look like at two different distances from the wall when you are using the reflector.

• 

• 

• 

• 

• 

• 

Above you can see some photos I took when I placed the FC-300B outside and punched it through a sheer curtain into a room using the included reflector, as well as when used open face. I have also included some shots with it pointing down at the table and being punched into the ceiling open face.

• 

• 

I also tried the lights with a DoPChoice Octa 3 softbox. While the light won’t fill the softbox completely, it still does enough to provide good results.

• 

• 

• 

• 

In the above example images I have just used the FC-500B and no other lights. The FC-500B was only set at 14% output. Both the FC-300B and FC-500B are more than capable of producing enough output when coupled with a large softbox for most interview requirements.

• 

• 

• 

• 

• 

Above you can see the light used with the optional Projection Mount. The Projection mount works really well and it allows you to really concentrate light into a tiny area.

The lights also work well when used with bounce boards or the CRLS reflector system when you combine them with the Fresnel or Nanlite Projector.　

Who are these lights aimed at?

I think a lot of people who are in the market for a compact-sized powerful bi-color light will be looking closely at these lights, especially given their reasonably low price and the fact that there are quite a few affordable lighting modifiers that are available for them.

They are certainly priced to appeal to owner-operators who are looking for a powerful and reasonably lightweight jack-of-all-trades lighting solution. The versatility of the FC-300B and 500B allows them to be used as a hard light source, a soft source, a fresnel, a gobo, or just about anything else you want it to be with the correct modifier.

Both fixtures are arguably going to be more suited to indoor use than location work, and if one of your requirements is being able to remotely power a light using camera batteries then there are better options available.

Price & Availability

The Nanlite FC-300B retails for $479 USD and the FC-500B costs $699 USD. This makes them very affordable given their performance and capabilities. Both lights are now available to buy. This price is likely to make them very appealing prospects for those shooters who are looking for a reasonably lightweight and powerful spotlight that offers good performance without emptying your wallet. However, in saying that, competition in this space is very fierce.

Optional Extras

The Nanlite FC-300B and 500B can be used with Nanlite’s own accessories, but because it also comes with a Bowens mount adapter, there are a ton of affordable accessories you could also use.

Conclusion

The Nanlite FS-150B and FS-200B, like most of Nanlite’s fixtures, are solid offerings. They are both color-accurate, and they feature a good amount of output. Spotlights like these offer a lot of versatility and they can be used for so many different applications and that is certainly why so many people are using them these days.

Having the ability to use the FC-3000B and FC-500B with a wide array of lighting modifiers gives the lights even more versatility.

The interface and operating system are basic, but they are easy to use. The app is also pretty basic, and while there is room for improvement, again, it does its intended job. The build quality is ok, but they aren’t as robustly made as some of the other competing lights in this space, however, in saying that, a lot of the competition is also significantly more expensive.

The fan noise is very minimal with the FC-3000B and won’t be a concern for most people. The fan noise is slightly louder with the FC-500B and you need to be aware of that if it’s placed too close to where critical audio is being captured. The small size and lightweight nature of the fixture make it a great option for anyone who is traveling. A couple of these lights with a few of the modifiers and you could have a relatively small and compact lighting kit that could handle a lot of lighting requirements. However, because you can’t power them remotely from a simple battery solution that does somewhat limit their flexibility.

The quality and color consistency of Nanlite fixtures over the last few years have improved a lot. The FC-3000B and 500B offer fantastic value for money. They have tons of output, they are lightweight and compact, and they offer good color rendering. If you are looking for a COB spotlight that won’t empty your wallet and you don’t need to run lights remotely from camera batteries then the FC-300B and FC-500B are certainly worth looking closely at.
