The
The unit incorporates two clickable, endlessly rotating knobs. Turning one knob controls the flicker-free dimming adjustment from 100 to 0% brightness, while turning the other knob controls the color output of the unit. In addition, the knobs can be clicked to select function on the fixture. For example, clicking on a knob enables quick switching between 3200 and 5600K when the fixture is in CCT or Filter mode. A new feature allows you to toggle Bluetooth on/off by holding down the menu button.
Luxli Conductor app
The Viola 2 can be used in conjunction with the free mobile device app, the Conductor, which allows you to individually control or link together multiple units. With the app, you can adjust the output of the light to match output, CCT, color, saturation, filters, and effects.
The app also allows you to sample the color and brightness from a video image, such as a campfire, on your mobile device and have that sample control the brightness and color output of the light. The fixture powers from 7 to 15 VDC via a 2.1mm power port or by the included battery. Mounting is via the built-in 1/4″-20 threaded mounting hole
Calibration Results
Each Viola 2 fixture comes with a Photometric datasheet that shows that unit’s tested output. This sheet is generated at the factory from testing each light fixture after calibration. The information includes the calibration date, model, and serial number of the fixture being tested as well as graphic depictions of the fixture’s performance in CRI/TLCI versus Kelvin output, deviation from Kelvin across the range, lux across the supported Kelvin range, deviation from Planckian locus (±green shift), color gamut, and beam angle measurement.
Discrete 5-Color LED Emitters
The Viola 2’s LED emitter design consolidates all five colors—RGBAW—into one emitter. The A and W represent amber at 3000K and white at 5600K. Unlike the original RGBA emitters that must add blue to their amber light to approximate daylight, the Viola² provides a wide variable color temperature range that maintains an average CRI of 95 throughout the entire 3000 to 10,000K range.
RGB Mode
RGB mode allows you to maintain total control of hue and saturation. Dial in nearly any color of the visible spectrum in 1°
Filter Mode
Set your white balance and then select between 150 Lee-equivalent digital gels. Whether you’re using technical filters for color correction or creative gels for theatrical effects, the Timpani’s filter mode provides a wide variety of customizable color options. It’s just like putting a gel in front of the actual light, but without the light loss. Also accessible in the filter mode are Chroma Green and Chroma Blue, for a saturated output to create clean keys
