I"m using a 50 watt CHE. The lamp housing is pretty big, they didn't have any smaller ones at the store, so i bought one just cause I needed one.

Yes I am running a thermostat..my room is cold so i have UTh's on both sides...One is running on a rheostat set at 82, and the hot side is regulated by a herbstat set at 92. Herbstat was the best thing I have bought for my enclosure, so easy and efficient


Edit- I have now also tapes down tin foil on top.
