The big dome is my 150W basking bulb (I know Tom mentioned downgrading it, but when I did that it wasn't getting warm enough)
the little due dome has a 100W CHE in the right side. The left side is empty/unplugged.
110 is a little too warm. It will contribute to pyramiding. The idea is to use any bulb you want and adjust the height of the bulb to get the correct temperature under it. Lower wattage bulbs are less desiccating, and more energy efficient too. You just have to lower it down a little bit to get the correct basking temp.
