The new RPS Studio CooLED 50 Light is the latest in lighting technology. Using just 50 watts of energy, it produces as much light as a 500 watt incandescent photoflood without the heat and at a daylight 5200°K making it perfect for either still or video work. Featuring a single 50 watt LED that has an average life of 50,000 hours (thats burning 8 hours a day, 5 days a week for over 25 years), and a built dimmer, this light will prove to be an economical, environmentally friendly workhorse. When coupled with the optional battery pack, this unit can be used when there is no AC outlet available. Comes complete with a removable 90° reflector, barn door set, diffuser, and AC power supply with cables. Other optional light modifiers are also available. An optional DC power pack (RS-5560) is available.
