The YN-600II light is part of a series of LED lights from Yongnuo Digital. This tungsten/daylight adjustable device offers two dimming modes (coarse and fine), an IR remote control, four barn doors, a power/brightness adjustment knob, fan cooling, and two filter plates (one orange, one white). Up to three lights can be grouped together via the IR remote control from a distance of up to 49 feet. A downloadable mobile app is also available to control the light. Designed for DSLR and camcorder shooting, the YN-600II light can be powered by two Sony NP-F series batteries or via an optional power adapter. A numerical LED display at the push of a button shows the remaining battery power. The YN-600II LED 3200-5500K light can be mounted on a tripod (not included) or held in hand with the included handle.
