It is intended to give the impression of natural light coming from above, but is in fact a recessed light cove that houses a 4 foot long warm fluorescent T5 bulb in an enclosed damp-proof housing. Hi -output LED strip fixtures are another energy efficient light source for this application.

beautiful effect. i'd love to do something like this in our bathroom. how deep is the cove? and how tall? is the fluorescent housing visible from below? does the fixture house 1 bulb or 2? and how many watts is the bulb? thank you!
