Ceiling-Mounted Diffusers

Ceiling-mounted diffusers provide ambient light, and are meant to distribute light uniformly throughout the room. Diffusers are made of clear or translucent glass or plastic, and are available in many sizes and shapes. They can accommodate a variety of bulbs including CFL, LED, and linear or circline fluorescent. They are easier to install than recessed fixtures because they mount on an electrical junction box in the ceiling, and do not require cutting into the ceiling surface. Supplement ambient light from a ceiling-mounted diffuser with a downlight, table lamp, or other fixture to provide task lighting for reading, cooking, washing dishes and other activities that require more light.
