I've used 15 watt bulbs in my cages for years. You can put your hand right on the bulb for hours and it won't even get uncomfortable, so I don't see how it would be possible to burn a snake. On my larger cages I use higher watt bulbs and build bulb guards. However, I didn't follow my own rules on this one. I used a 40W "Reveal" bulb and just dialed down the temp with a dimmer. However, after reading the above post I put my hand on the bulb and it WAS too hot, even dimmed down. So I immediately replaced it with a 15W bulb, until I can finish the bulb guard that is pictured below. The finished bulb guard is from another cage, but should be what the new one looks like when I'm finished. Thanks for your concern, you might have averted an injury to my beautiful JCP.
P.S. you might notice the openings in the wire are smaller on the new one, the first one was for a good sized boa, I've used a smaller sized opening with this one and I think I like it better.
