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.
