...BAD BAD bengal cats (like I do LOL) or something else which could knock the lights off the tank, or are using an incorrect fixture type, I don't know why leaving the lights on the timer should present a problem. But then again, leaving the spotlight off for a couple of days wouldn't be a problem either, unless your guys are thinking about brumating, in which case they would probably decide to right then LOL. BTW, using a "spotlight" is a bit more risky than a "floodlight", since the spot tends to create some really hot... spots. I like the full-spectrum halogen floodlights in various wattages.
