The RPS Studio 200 Watt CooLED Studio Light uses a single 200 watt (energy usage) LED that produces light equal to approximately 1,600 watts of incandescent light when the 8” reflector is attached to it. The light output is adjustable in half stop increments yet the color temperature of the light stays a constant daylight (5200°K). Mounts to any standard 5/8” light stand spigot. The LED is rated for 50.000 hours usage (that’s equal to running at full power for 8 hours a day, 5 days a week for over 25 years). The on/off switch is in the 3 meter power cord. Complete with 8” Bowen’s style mount reflector that will accept a standard umbrella, shower cap style diffuser, and protective cap.
