The YN900 II 5500K LED Panel Light from Yongnuo is a daylight-balanced LED light that consumes just 86W of current and outputs many times that in tungsten equivalency while maintaining a high CRI for accurate color rendering. The light measures 17 x 15.7 x 3' and has a color temperature of 5500K, great for shooting outdoors or in venues with large windows. You can change the color balance with the two included color temperature filters when needed.

Dimming is variable, and while you can make adjustments locally on the unit, the YN900 II has a built-in 2.4 GHz receiver and comes with a wireless remote that can control dimming and on/off functions at distances up to 49 feet. There's also a free, downloadable App that lets you control the fixture with a smartphone. The light can run on AC power via its adapter or on four separately-purchased NP-F750 lithium-ion batteries.
