Hello, and to BP.net.
-Where exactly are you measuring your warm side temps and what are you using to measure them with?

-Do you have any type of controllers (thermostat or dimmer) for the heat rope and lamp?

-What type of substrate are you using and how thick is the layer?

-How many hides do you have in the tank?

If you could post a photo of your tank set-up it would help.
