The whole ceiling will be replaced, everything rewired, so i'm not limited at all there.
I like the idea of LED, especially daylight balanced so it's nice and bright in there (daylight balanced help wake you up better than tungsten). I will probably have very low level warm white as well, on a separate switch, for when the GF wants a bath or something. The daylight lights are negotiable, perhaps a dimmer or just switchable levels is a better idea. I might also put some accent lights in, LED strips or something, if it can be done well.
Can anyone make any suggestions about good bathroom lighting?
