Until you get an alternate heat source and thermostat, you can also try using a lower wattage bulb. In my early years of keeping, the only local choice were heat lamps or ceramic heat emitters. I had to play around with wattage to find what worked best for the style enclosures I had - some glass tanks, some homemade wooden or melamine cages. I switched to under cage heaters for several years when I bought all Vision cages (plastic). I switched to radiant heat panels a few years ago when I upgraded to pvc cages - too thick for exterior heat in my opinion. As everyone else has said, a thermostat is a must, regardless of heat source. Best of luck with your new little one!
