I prefer wall sconces for vanities. They send the light towards your face, thereby not creating shadows which recessed lighting might cause.

On the mirror is great. We've had quite a few customers do it and love it.

As for picking the fixture, check out some stores and find fixtures you like. Then check to see how visible the guts of the lights are. If you have one where all the insides are covered, you have a winner.

Thanks. I will check that out when ordering the scones.
