A Jackson’s Cham should never be in temps more than 80 degrees. If the air temp is already 80 degrees he doesn’t need a basking bulb, he can digest just fine at 80 degrees. You have to remember that Jackson’s are a montane species so they require lower temps th,an other chameleons.You don't? Where would the cham go for concentrated heat to help with digestion?
The basking bulb
A basking bulb is any light bulb that generates heat to create a warm spot at the top of the cage. Reptiles are ectotherms (cold-blooded), meaning they need to absorb heat from their environment to regulate their own body heat since they cannot produce it. Therefore a temperature gradient in their cage is essential to good health. They need a warm place to bask in order to digest food properly but they also need cooler places to cool down so they do not overheat since they can’t sweat or pant. A basking bulb provides warmer temperatures at the top of the cage but should not be so hot that it heats the entire cage. Your chameleon will utilize different temperature zones throughout the day depending on its metabolism and needs.
