Compatible with the Hensel 12-inch reflector, the Hensel Honeycomb Grid Set 4 pcs. No. 1-4 is a must-have for getting narrow-angled light without suffering any loss of power. The set includes four honeycomb grids with varying angles of beam spread: 10°, 20°, 30°, and 40°. Each grid narrows the light spread from the reflector on which it may be mounted. You can use these grids for adding dramatic effects to a background or subject, or for accent lighting.
