Well, I thought I made sense, but I'm confused by your new post above, so maybe I shouldn't post at 3am. 
I have no idea what your setup is now and I'm confused. So here is, in my humble opinion what a leo setup should be:
Pick a "warm corner", you want it really warm in the day and warm at night.
Put a properly sized UTH under that.
Find a visible spectrum heat bulb, ideally one with UV as well and clip, hang or otherwise attach it over the same "warm spot".
Buy as cheap or expensive timer as you like, in the daytime have the visible heat lamp on and UTH off (see my other post about starting a fire and violation of warranty)... at night, UTH comes on and light goes off.
If you are talking about one of those night light bulbs that supposedly aren't seen by geckos, dump it in my opinion. (We are currently having a discussion about that on the crested board.) People have posted here that leo's irises respond to them so at the very least they are sensing something from them.
So ideal setup: light/heat lamp on during the day, UTH at night.
Again, my humble opinion there are people here that don't use lights or don't use UV lights... but my 9 3/4" female (no giant blood line) seemed to have grown well under these conditions.
Hope this is more clear.
