Source Four® LED Series 2 luminaire is the result of that dedication. With the brightest output and the boldest rendering of the colors you use most, the Source Four LED Series 2 introduces a whole new level of LED lighting that can be used anywhere. ETC's x7 Color System™ combines a balanced recipe of up to seven colors to create evocative color mixes. The Source Four LED Series 2 Lustr array takes the idea even further, with the addition of a lime-green LED emitter. The Daylight HD and Tungsten HD arrays were designed for the studio and other applications where high-definition lighting is a must. With flicker-free operation even at high speeds. The Source Four LED series 2 daylight HD and tungsten HD arrays look great on screen.
