Small but mighty, Godox's Witstro AD200 speedlight offers wireless support with Godox's 2.4G X system and 200Ws / GN 52 output. That's pretty incredible – for comparison, many speedlights struggle to put out just 100Ws.
The unit is powered by a rechargeable lithium-ion battery pack rated for 500 full power flashes, and provides TTL support with Canon, Nikon and Sony systems when used via wireless control. Output can be adjusted in eight steps, and the AD200 can be used with a number of accessories and diffusers.
