The Hensel Honeycomb Grid Round Black No. 4 is a nifty accessory that helps you control the spread of light from your Hensel flash head in an efficient way. It offers a wide beam-spread angle of 40° with a sharp fall-off light pattern. Apart from subtly softening the light, this grid also prevents stray light from passing through to a certain level. This grid is compatible with Hensel 12-inch reflectors.
