Master Bath has been in use for about 9 months now and we're really pleased with this lighting selection!  We have 3 of these Kovacs over the 2 sink vanity- we took a lot of time making sure they were the right color, size, brightness, and are dimmable- they are framing 2 mirrored med. cabinets over the sinks.  The light tubes are raised away from the wall (by virtue of the small mounting box) so the light is in front of the mirror a bit.  These could also be mounted on top of a mirror -we looked at this for another bath but I didn't want a repeat so chose another Kovac.  Can't dim too low- or it gets "jittery" -but low enough when you want.
