The speedlight head
outputs the standard look of an on-camera flash that can be modified
using an optional softbox, beauty dish or umbrella. The bare bulb head
features a removable flash tube and produces 360 degrees of soft,
bright, nearly shadowless light. The head uses optional reflectors that
focus the beam angle and give you directional control. The AD200 has
impressive core features such as 200 Ws of power adjustable in 8 steps
from 1 128 to 1 1, recycling from 0.01 to 2.1 seconds and flash
durations as short as 1 11,300 sec. The flash runs on a removal
rechargeable lithium battery that will give you up to 500 full power
flashes and thousands of lower power flashes.
