I like both of the leds that ci-lantro posted. We have one horizontal one over a 24" vanity in the standard 5' x 7' guest bathroom, with 10' ceilings, and it lights up the room more than adequately. Yes, there are additional high hats over the tub/shower, but unless someone is using the tub/shower, those lights are never turned on.

Edit: PS - I love that tile and yes, fixtures should have square edges, not round.
