I'm putting together a 32"x18"x12" wood-and-glass enclosure for my BP. For daytime lighting, I have a 13-watt fluorescent light. I'm thinking of putting a red LED light for nighttime lighting and I'm wondering how much is acceptable and how much is too much?? I'm planning to use 1-watt bare LED bulbs (no reflector). One bulb should be enough to illuminate shapes but that's about it. Two, of course, would be better from a viewing standpoint but I'm wondering if it'll be too much for the BP's welfare.

Any opinions??
