As long as it isn't LED that can be used as a basking/grow light combination. I have separate grow lights but all of my basking lights are 65w indoor floodlights.
It’s not LED. A 65 watt flood light bulb is a strong basking bulb for a chameleon unless you raise it up off the screen. If you get it on a dimmer you can easily achieve 80-85 degrees at basking,
