I have my baby Children's python in a 10 gallon tank. With a small UTH on one side and a light on the other ambient temp stays 82 during the day. I have to really watch it because if the sun in shining and the house warms up more than normal at all it's getting hot in that tank. I'm a beginner, but I know 2 lamps would make a 10 gallon way too hot, as I have to really watch mine with one. JMO
