The YN300IV LED RGB Panel is one of a series of on-camera LED lights from Yongnuo. Small enough to be used on or off camera, the compact tungsten/daylight-adjustable unit measures 10.2 x 9.2 x 3.9' and has 316 CCT LEDs. It also has 60 SMD RGB LEDs to offer literally millions of custom colors. The light can be controlled by an optional remote that adjusts CCT and RGB functions as well as brightness control. The YN300IV runs on AC current but it will also run on optional NP-F batteries when AC power is unavailable.
