The RPS Studio CooLED 100 Studio Light from Dot Line uses a single LED to produce the equivalent of approximately 1,000W of incandescent light. The light intensity is adjustable in half stop increments while the color temperature of the light stays a constant daylight-balanced 5,200K (+/- 200K). This LED is rated for 50,000 hours of use; that's equal to running at full power for 8 hours a day, 5 days a week for over 25 years. The fixture has an inline switch in its 9.8' power cord and comes with an 8" reflector with a Bowens-type S-Mount. A full line of light modifiers are available, such as umbrellas and "shower cap" diffusers. The CooLED 100 mounts to any standard 5/8" light stand stud.
