This Bi-Color Round LED Video Light measures 18' and has color variable from 3200 to 5600K while maintaining a CRI of 95 for faithful rendition of colors and even the subtlest hues. It's dimmable from 1-100% and has a back-lit LCD indicator to show light level, color temperature, and battery life status. At only one and a half inches thick, the light fits where other lights just can't go. You can work close-up without fear of causing discomfort to your talent since running the light all day at full power barely makes it warm to the touch. You can make adjustments locally on the fixture, or purchase an optional 2.4 GHz remote to make them wirelessly at a distance. The fixture can be used anywhere in the world thanks to its multi-voltage power adapter but it can also run on optional V-mount or NP-F batteries when AC Power is unavailable.
