Over a decade of research is realized in ETC's third generation of the Source Four LED. With two arrays to choose from, you can guarantee better colors from high-quality light with maximum brightness. The Lustr X8 array uses deep red LEDs to create a warmth similar to tungsten. The Daylight HDR array gives you a wide range of tunable white lights from warm to cool. You'll be amazed at how both arrays enhance fabrics, scenery, and most importantly, skin tones.
