I bought the light bulb Ursula uses and found a $36 reptile "brooder light" on sale at a local pet store for $18. I have to pick up the light and I'm having the light bulb shipped to me, so hopefully #1 they fit together and #2, they work together.
It says compatible with their brand of halogen light bulbs (and it says the light bulb is halogen) and some folks say they don't use the brand's light bulbs, so I don't think using their brand is a must. And I figure reptile lights have to be on for hours every day plus they use a higher wattage bulb than I'm using, so I should be good.
But, once I get the stuff, I'm going to see about making a pvc stand like the picture above.
