A few days ago, Godox unveiled its new KNOWLED TP2R/4R/8R RGBWW Tube Lights that are available in 2′, 4′, and 8′ lengths. They look to be direct competition to the amaran PT2c/PT4c RGB LED Pixel Tube Lights that were also just announced.
The KNOWLED RGBWW Pixel Tube Lights have an adjustable CCT range of 2000 to 10000K. There are also Gel, HSI, and RGBWW modes that you utilize to create a vast array of colors and lighting effects.
As these are pixel tubes, up to seventeen customizable special effects, and three built-in pixel effects can be used to further create unique lighting effects.
Key features
- For Studio, Film & TV Production
- 2000-10,000K CCT; RGB Mode
- Onboard, DMX, CRMX, Bluetooth Control
- CRI 96 | TLCI 96
- 17 Preset Special Effects
- Built-In Battery / AC Power / V-Mount
- 3/8″ Mounting Thread
You can control the lights onboard or via DMX, CRMX, and the Godox Light 3.0 (Bluetooth) app. Depending on your requirements, the lights can be switched between 8 and 16-bit modes.
Like a lot of tube lights these days, they feature a proprietary rechargeable Lithium, 14.4 VDC, 3000 mAh (Built-In) battery. You can also power them via AC or through a V-mount battery or similar with an adapter.
When it comes to output, here is what Godox claims:
Godox TP2R Pixel RGB LED Tube Light (2′)
As a comparison, the amaran PT2c RGB LED Pixel Tube Light (2′) has a claimed output of 18 fc / 194 Lux at 3.3′ / 1 m when set at 5600K. The amaran draws 16 W, while the Godox draws 33 W.
Godox TP4R Pixel RGB LED Tube Light (4′)
As a comparison, the amaran PT4c RGB LED Pixel Tube Light (4′) has a claimed output of 30 fc / 332 Lux at 3.3′ / 1 m when used at 5600K. The amaran draws 32 W, while the Godox draws 64 W.
As far as mounting is concerned, the tubes have a single 3/8″ receiver. Although, Godox also makes a range of optional accessories, including 2, 4, and 8-light brackets, modifiers to control shape and spill, and floor stands.
One of the most interesting accessories is the Godox TP-P600 Power Box for TL and TP Series Tube Lights ($459 USD). The TP-P600 Power Box has power output terminals to simultaneously power up to eight TL and TP series tube lights. When used as a single port power supply, it can support lights up to 105W. It supports up to 600W when multiple ports are engaged.
The tubes can be purchased individually or as multiple-light kits.
