The 5.5" Dome customized to Vivid Chameleons & Habitats requirements for heat diverge to the 5.5" diameter of the fixture using a 50W or 75W bulb.
We do not recommend using 100W or 150W bulb as it might be too hot for your chameleon. Ideal basking spot during the day is 85F. Please use a temperature gun to measure the basking spot to avoid overheating the chameleon.
