What type of heat?

I have the T8 and use RHP as my only heat source. It keeps the ambient temps perfect. Ive had it for 2 years now and never had an issue. Once you get the temps dialed in your good to go. Everyone on this forum will have a different opinion. So in my limited opinion the RHP is the way to go.

EDIT. I keep my heat at 67 degrees in the winter without struggling to keep temp up in enclosure using only RHP.

Gotta chime in also. I am another who only use RHPs as the only heat source in my cages. My ambient temps are whatever I need them to be. Whatever temp I set, they stay consistent. Even in florida (northern) it can at times during winter get somewhat chilly. My snake room is last in line as far as house heat. It is by far the coldest room in our house. It has easily gotten in the mid 60s in the room during winter cold snaps and all of my RHPs constantly keep my temps stable at what I want (80+) in all my cages (6).
