The light has a wide adjustable color temperature range from 2800 to 6500K, backed by high CRI/TLCI ratings of 96/97 to ensure an accurate rendition of color. The light is dimmable too, in fact the Knowled has four dimming curves to make sure your color is accurate regardless of how you set the intensity level. While you can adjust brightness and color locally on the fixture, you can also make changes wirelessly with 2.4 GHz bandwidth, DMX, or Bluetooth. There are 21 lighting effects, including flash, lightning, TV, broken bulb, candle, fire, fireworks, and more. The light runs on universal 100 to 220 VAC current via the included controller, or you can use an optional V-mount battery when AC power is unavailable.
