The grid set consists of four, black grids: 10°, 20°, 30° and 40°. The grids provide a basic spot light effect and have a sharp fall-off light pattern. Dyna-Lite Grids snap into the Dyna-Lite grid holder. The grid holder is the interface between the grids and your Dyna-Lite 1015 and 2040 flash head. Dyna-Lite 2040 Accessory Output Guide
