Gecko Heating Help

So I have a UTH, which gets the floor to about 93 degrees on the hot side, but the air temperature is a little cooler than I'd prefer (around 80 degrees). I had a 75W infrared bulb that shouldn't have disrupted their circadian rhythm, but it made the floor too hot (around 105 degrees). I want to raise the air temperature a bit, but I don't know how. I've seen 25W "Moonlight bulbs" or something that are supposed to provide a little heat without giving off much visible light to bother their nocturnal behavior, but I don't know what to use.

I just realized I posted this in the wrong sub-forum... My bad, I'll do better next time

Welcome to GF! I moved the thread for you. I honestly think that 80F air temp is more than adequate for a leopard gecko. They are arid, not tropical, and I would bet that the weather in Afghanistan/Turkey is pretty cold in the winter. In my opinion, high air temps, especially when combined with heat from above and very low humidity, will dehydrate them and can even dry their eyes out (check this out: http://www.geckotime.com/eyelid-dysecdysis-in-leopard-geckos/)
