I use a UTH and a CHE. CHE needed to get my ambients high enough ATM since my roommates really love keeping the place cool. UTH at 95F, CHE keeping the air about 90F (H), 80F (C). Big pain for the humidity, though.

Don't use a red since I've never found them to offer anything a CHE doesn't other than the light, and I personally prefer to make sure my BP has a day/night cycle. Some people's snakes do fine with red light, others don't.
