yes on the reptisun, though I prefer the t-5. Seems to be more bang for the buck. Most people seem recommend the 10.0 since many chams spend like 2 hours anyway near it and it looses alot of its UVB in a short period of time.
As for the other bulb, that will heat roughly like 53 watt bulb since that's what it actually uses. Much in the way that a "75 watt" LED bulb throws off very little heat since it is like 20 watts. You can still find regular cheap incandescent at the Dollar Tree and Dollar General. I stocked up at the Dollar Tree at 3/$1. I'm guessing they will only be available as specialty bulbs in a year or two since you can now get LEDs at $1 a piece.
