This is a specific conversation about Reptile setup — getting the environment right — ask about yours and get one honest answer for your exact situation.

Getting your basking spot temperature right is one of the most critical things you'll do for a bearded dragon — they need that spot hitting 40–42°C to properly digest food and regulate their immune system. Reptile welfare is almost entirely determined by environment: temperature gradient, UV lighting, humidity, and substrate all need to match what they'd experience in the Australian outback. Get it wrong and you're looking at chronic stress, appetite loss, and illness that builds slowly and invisibly. So — how old is your beardie, what size enclosure are you working with, and are you starting from scratch or trying to verify an existing setup?
She's about 8 weeks old, just got her yesterday. The enclosure is a 4x2x2 vivarium and I'm setting it up fresh. I have a basking bulb in place but I genuinely don't know if the temperatures are right. The dial thermometer that came with the setup feels pretty vague.

That dial thermometer is almost certainly useless — they're notoriously inaccurate and they measure air temperature, not the actual surface your dragon is sitting on. For a basking spot you need surface temperature, and the only reliable way to get that is an infrared thermometer you can point directly at the basking surface. What thermometer are you currently using, and do you have any idea what temperature it's reading at the moment?
It's just reading about 38°C but I have no idea if that's the surface or the air nearby. I don't have anything else to check it with.

Right, that's almost certainly air temperature close to the bulb, not the slate or rock she'll actually be sitting on — and that difference can easily be 5–8°C. For an 8-week-old beardie you want the basking surface itself at 40–42°C, with the cool end of the enclosure sitting around 25–28°C. Get yourself an infrared thermometer. The one I'd point you to is the Etekcity Lasergrip 774. It's accurate to within 1.5°C, has a laser pointer so you're measuring exactly where you aim, and gives you an instant reading. It's around £15 on Amazon UK and it's what most experienced keepers use for exactly this. Point it at the basking slate, not the air above it, and you'll know immediately whether your setup is safe.
That makes sense. Should I be checking anywhere else in the enclosure too, or is the basking spot the main priority?
inparticular.ai
The basking spot is the priority to get right first, but yes — once you have the Lasergrip you should also check the cool end surface temperature and the floor temperature roughly mid-enclosure. You want a genuine gradient so she can thermoregulate by moving between zones. For an 8-week-old, cool end surface around 25–28°C and you don't want the floor dropping below 22°C at any point, especially overnight. The same infrared thermometer does all of that in seconds. Once those readings are confirmed, your next focus should be verifying your UVB strip is the right output and positioned correctly — but temperatures first.
Perfect, that's really helpful. I'll order the Etekcity today.

Good call — it'll pay for itself in peace of mind alone. Once you've got confirmed temperature readings across the gradient, come back and we can look at your UVB setup and substrate. At 8 weeks she's in a critical growth phase and getting the environment dialled in now makes everything easier long-term. Good luck with her.
