This is a specific conversation about Reptile heating and lighting — the critical factors — ask about yours and get one honest answer for your exact situation.

Getting heating and UV lighting right is genuinely the single most important thing you can do for your reptiles — the majority of common illnesses, from metabolic bone disease to respiratory infections, trace back to incorrect temperatures or inadequate UVB. You've landed here asking about a shared thermostat solution for two very different species, which is worth thinking through carefully before you buy anything. So — what enclosures are they in, what basking and ambient temperatures are you currently targeting for each, and what heating equipment are you running right now?
Sure — the beardie is in a 4x2x2 wooden vivarium with a 150w basking bulb, targeting around 42°C basking and 28°C cool end. The blue-tongue is in a 3x1.5x1.5 wooden viv, 100w basking bulb, targeting about 35°C basking and 24°C cool end. Both are adults. I'd love one thermostat that can handle both, ideally a dimmer type so the bulbs last longer.

That's a sensible instinct — dimmer thermostats are far better for incandescent basking bulbs than on/off pulse stats, which shorten bulb life and create an unnatural flickering effect. The honest answer though is that one thermostat controls one probe, so it can only regulate one basking spot at one temperature. What you actually need is one thermostat per enclosure — there's no safe way around that. What I'd recommend for both setups is the Inkbird ITC-306A dimmer thermostat. It's a proper proportional dimmer, handles up to 2000W, has a clear digital display, and the probe is accurate and robust. Buy two — one set to 42°C for the beardie, one to 35°C for the skink. It's the same unit, so you learn one interface, and they're around £25-30 each on Amazon UK, which is genuinely good value for the reliability you get.
That makes sense actually, I think I was hoping to cut corners but you're right that the temps are too different. Is the Inkbird definitely suitable for the wattages I'm running — 150w and 100w?

Absolutely — both are well within its 2000W capacity, so there's no stress on the unit at all. At 100-150W you're running it at a fraction of its rated load, which actually means it runs cooler and lasts longer. One practical tip: position the probe at the edge of the basking zone rather than directly under the bulb. You want it reading the temperature your reptile actually experiences at basking height, not the hottest point of the beam. That gives you much more accurate regulation and avoids the stat cutting the bulb too early.
Really useful, thank you. One more thing — should I be running the thermostat on the UV lamp as well, or just the basking bulb?
inparticular.ai
Never run a UVB tube or mercury vapour lamp through a dimmer thermostat — it will destroy the ballast and can be a fire hazard. Your UVB lighting should be on a simple plug-in timer, not a thermostat at all. The thermostat controls only the basking heat bulb. If you're using a combined heat and UVB bulb like a mercury vapour, you'd need a purpose-built on/off thermostat rated for those units — but for your current setup with separate basking bulbs and UVB tubes, keep them on separate circuits: dimmer stat for the basking bulb, timer for the UVB. Clean and simple.
Perfect, that's really clear. I'll grab two Inkbird ITC-306A units. Thanks for talking me out of the one-thermostat shortcut!

Good call — two thermostats is the right answer here, and the Inkbird will serve both of them well for years. Your beardie and blue-tongue have genuinely different thermal needs, and getting that dialled in properly makes a bigger difference to their long-term health than almost anything else. Enjoy setting it up.
