CHE should ideally be on a pulse state,
A che can easy right 150 degrees c at the bulb and Generate hot spots 60 degrees c and higher if unregulated, I had a heat mat thermostat fail yesterday and the heat mat when checked with a hand held ir gun was at 70 degrees c, unregulated heating elements can cause serious injury and death.
Use a good mat stat for the heat mat and a proper thermostat with a che.
