Yongnuo YN200 Battery Powered Speedlite

The YN200 Battery Powered Speedlite from Yongnuo is a 5600K flash head with a 2900mAh rechargeable lithium-ion battery that will give you up to 500 full-power flashes per charge. The head has an almost 360-degree beam spread similar to many bare bulb fixtures that can be modified and directed by the included reflector. The 200Ws head recycles in 0.01 seconds at minimum power and 2 seconds at full power, while its output can be regulated from 1/64 to 1/1. It also supports High Speed Sync speeds as short as 1/8000 second. The YN200 has an onboard optical slave for simple triggering from any flash unit but it also has a built-in 16-channel, 6-group radio receiver that accepts signals from Yongnuo YN560-TX II, RF603 and RF605 wireless flash triggers. It can also be triggered in a TTL master/slave configuration with Yongnuo flashes such as the YN862 series.
