This flash bulb correctly a bathroom or toilet, and especially the lighting is direct, no more waiting tens of seconds the brightness is maximum as could be the case with other lamps savings energy.
The white heat of the day (6000 K) was a bit cooled before buying (this is the case to say :-)) but that's the effect I was looking with white porcelain and black / brown.
Avoid in other parts of life, including the rooms or any room with paint / wallpaper where a warm color will make your colors more value.
I have not tested the drive.
