Jessiepa, it looks like you are using round gauge (dial) thermometers. If those readings are what you are basing the temps on, unfortunately you're not getting accurate readings and they can be off 20 degrees or more. So, I wouldn't recommend getting any higher wattage basking bulb OR heat emitter until you use a temperature gun or digital thermometer with a long wire & probe end to check them. Surely wouldn't want him overheating, that would be very dangerous.
