yes but when i talked to a vet here is what he told me:
-geckos need UVB to metabolize vitamin D
-they need vitamin D to metabolize calcium.
so i need a UVB light, which i have; but glass and acrylic block out most of the UV light.
i guess ill just save up and buy a exo-terra (the third size), or maybe just maybe i can convince my dad to help me custum build a tank.
Take a look at the book "Day Geckos in Captivity" by Leann and Greg Christenson (published by LIVINGART publishing) where they make the case that when properly supplemented with D3 and the correct vitamins day geckos can do well without UV light. I have had a gold dust day gecko for 3 years and a klemmeri for nearly 2 years without UV light and they are thriving.

You could always go with the "daylight" type of bulbs on top and just make sure to supplement them with 2 parts of calicum w/D3 to 1 part herptivite when dusting crickets/flies/etc.
A ratio of 3:1 works better. Its hard to explain but it does. You dont NEED UV but you still need lighting and you MUST dust every other to ever feeding.
I believe all creatures need some form uva/uvb in some degree especialy if you plan on breeding.
