The YN900 5600K LED Panel Light from Yongnuo is a daylight-balanced 18 x 16 x 3″ 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 color temperature is 5500K, great for shooting outdoors or in venues with large windows, but 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 has a built-in receiver and comes with a wireless remote that can control dimming and on/off functions at distances up to 49′. There’s also a free, downloadable App that lets you control the fixture with a smartphone. The light can run on AC power via a separately-purchased adapter or on four optional NP-F750 lithium-ion batteries.
