What are diffusers?
Normally, sconces are mounted above eye level so that the bulb and socket are not visible; however, in the instance that you may see down into your fixture, you may want to order a sconce with a diffuser. Diffusers are frosted lenses attached to the top of the fixture to conceal the view of the bulb. Diffusers are for cosmetic purposes; they do not protect the fixture from water. Diffusers are not sold separately.
