Witstro H200R Round Flash Head for AD200. The 3" diameter head attaches quickly and easily to the AD200, allowing it to tap into its 200Ws reservoir of power, while the H200R's spiral flash tube outputs a soft, wide beam of light with gentle falloff and a minimized hot spot. The head also has a 4.3W modeling light to allow you to preview your final shot. One of the head's handiest features is a magnetic front accessory port that allows very fast attachment of optional accessories such as barndoors, a honeycomb grid, a snoot, and diffusion and color filters.
