What is your ambient temperature? (Room temperature) I like to keep my basking temp for my 4 month old ambilobe at 80. In fact, I use a 15w bulb so it doesn't get any hotter. My ambient temps are 75. In the afternoon the temps rise because the cages are in front of my sliders, so I turn off the basking lights or they all sit on their branch under the bulb with their mouths open. I always make sure I mist well in the afternoon to cool them down. When it gets too hit I have a sheer curtain I drop over the window. Most of the time they don't have enough sense to go into the leaves.
