Eh, I'm with mstevens on the subject of tank lights. IMO, there's already way too much light from the average group of divers. In clear water, Sue Sue's penlight is plenty. It's easier on the marine life and helps one focus on finding stuff rather than just lighting the whole place up.
And IMO, there's absolutely nothing more jarring on a night dive than a tank strobe. If someone wants to disco at night, they should go to Señor Frog's.
