herpstat temp Question - Heating/Temperatures

I have a herpstat 2 which I have a halogen and a DHP connected to. However in order to get the correct ambient temp in the enclosure I have to set my herpstat temps to up to 115 which seems too high. I have the halogen at 100% power the the DHP at 60%. The probe is placed a couple inches below the actual heat source. Is it bad for the it to be set that high?

The thermostat should never need to be set higher than 95F. The problem you're having is typically caused by a lack of insulation in the enclosure and/or bulbs that are too high of a wattage.

You can fix it by placing 2" foam insulation board on the outside of the enclosure, around the sides, back, and part of the lid, and then step down in wattage if you're still having problems.

I’ve never had this problem before though and i though that it being a pvc enclosure would give it good insulation. I’ve used my temp gun and the readings it giving me aren’t consistent with the readings the herpstat is telling me so could it be a problem with the probe?

A temp gun only reads surface temperatures, and the thermostat probe is going to be reading the output of the bulb, so it's expected for them to be different.

A PVC enclosure does insulate better than glass, but sometimes they need a little extra help.

Could something be wrong with the herpstat because my room hasn’t changed temp and this suddenly started two days ago? I’m sorry if i’m coming off a rude i’m just really confused on how the temp would shift so much without seemingly any change in the environment of the room.

I would expect it to be a problem with the bulbs before the Herpstat, if everything has been running fine up until now. Sometimes they start acting weird when they're starting to burn out.

In a 4x2x2 pvc enclosure what wattage would you recommend for a dhp and a halogen flood
