The light should be a secondary source of heat, not a primary.
The UTH should be plugged into a thermostat, this is not an option, it's a must.
With a thermostat you will be able to set your "ground temp" to 90-92 and then add your secondary heat source for getting your ambient temperature correct.
A CHE is way better for this purpose, and last a lot longer too
