The Source Four LED™ combines the functionality and form of ETC’s Source Four® conventional spotlight with ETC’s Selador® LED x7 Color System and the user-interface of Selador® Desire™ LED luminaires. Performing at 30-40+ lumens per watt, the fixture is an energy-saving, color-changing stage, studio, and architectural light. Using the complete complement of Source Four lens tubes, the unit delivers a sharp, clean beam and crisp imaging. All accessories of classic Source Fours are compatible with Source Four LED. The optical performance and look allows it to blend into existing lighting rigs. The three versions—Lustr+™, Daylight™, and Tungsten™—each offer the same beam. The Lustr+ features the complete x7 color palette. The Tungsten and Daylight models produce maximum brightness at the respective warm (3,000K) and cool white (5,600K) color temperatures.
