The YN6000 Daylight LED Light Panel from Yongnuo is a daylight-balanced fixture measuring 16 x 16 x 3". It consumes just 50W of current and outputs many times that in tungsten equivalency. A high CRI of 95 ensures accurate color rendering and the 5500K color temperature is great for shooting outdoors or in venues with large windows.
Dimming is variable, and you can make adjustments locally or wirelessly with an optional remote from distances up to 49'. There's also a free, downloadable app that lets you control the fixture with a smartphone. The light runs on AC power via a separately available adapter or on optional NP-F batteries.
