There's several options that work. I don't keep BPs but I do keep other terrestrial species. RHPs are probably the most efficient heating method. I use a UTH as my primary heat source but I will add a CHE to boost my ambient temps during the winter. You could use a heat bulb but it'll bring your humidity down so you may have to work around that. I do think your hot side temps are a bit high. I keep mine around 88-90 tops.
