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. The Daylight HD array produces the coolest (4000 to 6500K), variable-white light that looks just like natural sunlight, and the Tungsten HD array creates warm (2700 to 4500K), adjustable-white light that mimics the performance of tungsten fixtures. Their temperatures and tints can be tweaked to perfectly illuminate individual skin tones, so they look great in person and on camera. Both arrays output an incredible amount of lumens, for the brightest light in their respective color-temperature ranges.
