Undecided Question

its a baby bearded dragon

also is there any online pet supply sites that allow me to pay with a money order because my mom wont let me use her credit card cuz she doesnt like animals

i have a bearded dragon in a 4ft x 2ft x 2ft vivarium and i only use a 50 watt heat lamp and this is enough, but i have a heat mat at least a half of the vivarium (on the hot side) but i do not plug it in unless the temperature is below 90, you should use uv lighting such as exo terra dessert uv as this is more intense and emits more uva and uvb than the other two versions.
hope this helps

own experience and work at a pet shop and specialise in reptiles

Yep. I have dragons and I use a metal domed shop lights you can get at Walmart in the hardware section. Its like 6 bucks. And I slap a 60 or 100 wat bulb in it and its works fine. Overhead heat is more like basking in the sun. I placed a flat stone on the bottom of the tank and the light on the top of the tank over the rock. It heats up the rock and keeps both sides of the dragons warm.
