ok thanks. and the 75w spot is ok for basking as long as the temperature is monitored and the distance from the perch is set accordingly? I originally had a standard 40w bulb but didn't like how it had to sit right on the cage, so I went with a more powerful bulb and raised it up. Also the added brightness looks nice.Thats perfect. The 10.0 is for the "pet tree" setups where you cant even find the cham, and you have a meter just incase.
