Okay, I'm waiting for some money to come in but I'll getting geared up to put in an order for a T8 with LEDs put in. But before I do I have a number of questions as to the best direction to go with this.

Will the UTH I'm using with my current setup (30 gallon tank) still work?

Instead of having a screen circle cut in for the CHE, I'm thinking up upgrading to RHP. How do those work? Do they just screw into the ceiling of the enclosure? And do they zap humidity like CHEs do? The humidity situation will be improved by default do to being a better enclosure instead of glass with a screen top, but I'm curious. And what wattage? Looking at one with 28 watts.

There's an option for locks on the doors. Is this something you can just add yourself or do they do modifications to make room for them (i.e. probably something you'd want to not mess with)?

There's a quicker ship option. Anyone have experience with that?
