Any night bulb, red, black etc will work. This is CORRECT. The laser light is completely different that incandescent. This is one reason humans can stare at a red reptile bulb for some time, but will suffer serious eye damage from only a few seconds of direct laser light. Snake pits can "feel" infrared heat with their pits, but their ability to see this color with their eyes, is minimal if at all. I am of course talking about the night reptile bulbs, and not a red Xmas Tree light. If you want to start messing around with R ratings and insulation, i'm sure you can rig up something, but think about all you must to when you need to wash out the tank. Much to move, and it if the snake is in a living area, as opposed to a snake room, it will be quite the eyesore. In addition, florescent lights give off minimal heat, and are not used to generate heat. Some of the posts above are anecdotal from hobbyists, and not scientific.
