I use medium lamps (8.5 domes) with 25 or 40 watt bulbs depending on where in the apartment the enclosure is (i.e. near an outside wall or not). I keep the lamps at least 8" above the top of the lid, be it a tub lid with soldered holes or a tank screen top with foil treatment, and most of my lamps have the built in dimmers.

I have found that blue bulbs work better than red for night, since they are less harsh and give off a bit less heat. Otherwise there is no real 'you must use THIS bulb' since BPs don't really need that added light. You just need to use something that won't suck out TOO much humidity and won't put out a ton of heat that messes up your temps. Personally I use ExoTerra SunGlo bulbs in all my lamps.

Of course, if you are one who can obtain the proper temps with just UTHs or RHPs, then that is the preferred way to go.
