I use strictly heat lamps. As long as you don't drop them and such, there shouldn't be any problem... i dont know what these people are doing to blow out light bulbs after a week! lol...
I have a 60 watt light on one side of the glass tanks (for those that i keep in glass tanks) on a rheostat. also known as a table lamp dimmer.
Reason why I prefer the light over UTH is it's really the best way to replacate natural heat. All natural heat comes from above, the sun. Then put a few climbing sticks in there and they will be up there climbing higher. My north american rats live in the climbing perches.
Also, get a digital thermo, not a stick on one. Those are only useful for water filled glass enclosures. reason is that it is telling you the temp of the glass, and since water and glass both conduct energy about equally well, the glass stays very close to the temp of the water. Air and glass conduct temperatures VERY differently, so the reccomended method is a thermometer that you put inside the tank, with a probe. A simple indoor/outdoor thermo you can get from walmart for $13 is what I use.
