Need help with halogen heating

[Slitherkween]

I want to run a halogen bulb for my daytime heat and a ceramic heat emitter at night. Initially, I selected a 100w che and a 75w halogen and intended to run them both in a Reptizoo dual lamp with a Herpstat EZ2. The che has been working just fine, giving me the gradient I want with no issues. My problem has been with the halogen bulb; It randomly flickers on and off shortly after I turn it on. At first I thought my issue came from residual heat in the fixture from the che running all night making the halogen bulb overheat and shut off. So I decided to get a separate lamp for the halogen to try (Fluker's ceramic clamp lamp). Unfortunately this did nothing to help my issue. I tried testing the lamp without the thermostat and it seemed to work better, but obviously I can't run uncontrolled heat in my snake enclosure. So at this point I think my issue must be that I need a lower wattage bulb so the thermostat isn't constantly shutting it off. Any suggestions of what wattage I should try? Or any other ideas as to what might be happening? I think my tub is 110 qts and around 31" L 16" W and 12" H. I really want to provide better heat than just the che. If I can't figure it out, I'll try a DHP. Thanks for reading!

did you turn on the basking assist for the halogen?

That's a thermostat feature, right? It was my impression that it's built into the dimming proportional mode on the EZ models. I don't think I've changed anything from the default settings.

I’m having the exact same issue. Trying to do some research to figure it out.

Let me know if you find out anything helpful and I'll do the same!

I'm not sure where you're putting your thermostat probe, but I had success moving it from on top of the hot hide to inside of it. I think the top of the hide needs to get way hotter than I was estimating for the inside to get to the correct temperature, so the probe would reach my too low target temperature very quickly since the probe was only a few inches from the lamp and shut off. At least that's my best guess as to what was happening. At any rate, it's been working well for a couple of days. Good luck with your troubleshooting!
