I have been having a hard time getting my basking temps where they should be. I have a dome light fixture that only handles 100 watts. I currently use the Zoo Med Repti Basking Spot Lamp 100w. It sits on top of the mesh lid to my 40 gal breeder tank. The basking spot is a rock that puts my beardie approx 10 inches (the rock itself is about 11 inches but then if you add my beardie to the rock it's approx 8-10 inches depending on what part of his body you measure from and how he is sitting etc) from the top of the cage where the light fixture sits. I have a temp gun that says the rock surface is usually between 85-90 degrees. What can I do to get the temp up? Is there a bulb that anyone can recommend that will work in my 100 watt max dome fixture? I also use the Reptisun 10 uvb light, and would prefer to stay away from a MVB because it worries me with my small children getting in and out of the enclosure and having to move the lights. Any ideas? Thanks!!!
