We have a fairly large shower stall with a footprint larger than a standard bath - 4x5 feet. I planned to install two of these but ended up only having enough room for one because there was plumbing along the way. Anyway, I wasn't too worried since most souls can get by with just one light. But the opening on it is only 2" x 2", so even with a 50 watt halogen bulb it puts out very little light (especially with the black bezel). I believe it gives about a quarter of the light you get from a regular 4 inch round incandescent shower light. to get a "normal" amount of light, it took me about 4 for my shower.
