hello all!

I'm having a problem with the heat source in my enclosure. I'm using a hot lamp that has adjustable heat. It's made by Esskay and it's a Delux Arizona Hot Lamp with 5.5" dome for a 10 gallon enclosure. It says "DO NOT use lamp over 75W with dimmer function." So originally I bought a 50W infared heat bulb made by Exo Terra. It made my basking spot for Medusa around 82-89.. sometimes up to 93 depending on the time of day, but more often it was always between 82-89ish. And it tended to be on the lower end of that range so it worried me. So I figured that I needed to buy a stronger heat bulb for my lamp right? So I bought a 75W, thinking that it would be fine. It WAS fine, and it did raise the temps on the basking side to 90-95ish, so I was happy, but then it ended up burning out on me in one day. So I thought maybe 75W was too high since the lamp said to not use 75W with dimmer function. So I bought a 60W, and it made my basking range 88-93ish, so I was happy with that also. But that burnt out on me after one day too!

So I assume there is something wrong with my heat lamp?? So I want to replace it ASAP. What kind do you guys use and where did you buy yours from? I'm getting frustrated with mine and tired of buying light bulbs!! Thanks..
