T8 vs. T12 VS. Twhatever

I'm thinking about getting some T5's soon. Do they really burn that hot? I felt one in the store as it was on and it didn't seem all that warm.

If I am using two 4 foot T5 bulbs with a 4 foot terrarium, would the humidity and heat still be an issue?

havent noticed to much extra heat on my normal T5's......the HO-T5's for my lil reef tank do put out noticibly more heat.....
