Im confused as to why your going back to the Heat Bulb idea? The CHE for 75+ ambient temps and the UTH for Hot side is best route for what you have now. Balls love UTH's. The CHE (as far as the way i explained to use it) was always for the cool side temps as you wont get 90 out of it with a tall aquarium style tank. That would be good for a lizard up on a branch not a snake on the substrate, heat rises and your starting out high to begin with using Lamos or CHE's not to mention glass is a bad insulator and you have a darn screen ontop hahahha. You also will never get Humidity over 50% steadily trying to run 2 lamp type heaters. They would dry out a puddle in a rain storm lol.
UTH Hot Side, CHE cool ambiant..
Run dimmer on UTH for 91 on glass.
Dont ever use tape inside a enclosure. Thats like pouring acid on your skin. Use silicone if you want to tack things down. I tack my Probe in hide under the substrate paper with silicone its safe for the snake.
Cant think of anything else right now. Your almost there just use the info to tweek things.
