Hermann tortoise heating & lighting starter kit

Getting heating and UV lighting right is genuinely the single most important thing you'll do for your Hermann tortoise — the vast majority of tortoise health problems, including metabolic bone disease and respiratory infections, trace back directly to incorrect temperatures or inadequate UVB. Before I point you toward a setup, I need to know: what size enclosure are you working with, and do you have anything at all already, or are you starting completely from scratch?

Perfect setup for a juvenile Hermann, and a 90x45cm tortoise table is a solid start. For that size enclosure you need two things working together: a basking spot hitting around 30–32°C directly under the lamp, with a cool end around 20–22°C, and a UVB output strong enough to synthesise vitamin D3. Hermanns are Mediterranean tortoises and need high UVB — you're looking at a UVI of 2.9 to 7 in the basking zone. What's your budget ceiling — are we talking under £50 total, or do you have a bit more flexibility, say up to £80?

Exactly the right mindset — buying cheap twice always costs more. For a 90cm tortoise table, the single best value combination is the Arcadia T5 UVB Kit in 6% (the 'Forest' strength is right for Hermann tortoises) in a 24-inch size, paired with a separate halogen basking bulb. The Arcadia T5 6% 24W kit comes with the lamp, reflective hood, and cable — it runs around £45–£50 on Amazon UK. For basking, a simple 50W halogen flood bulb (Arcadia or even a standard halogen from any hardware shop) sits in a basic ceramic lamp holder and costs under £10. That's your complete, properly specified setup for well under £80, and both components are replaceable cheaply when they eventually need swapping out.

Yes, and it's worth the small extra spend. A digital thermometer with a probe costs around £8–£10 on Amazon — place the probe directly on the substrate under the basking lamp to check the surface temperature. Point a cheap infrared thermometer (also around £10) at the basking spot for a quick surface reading. You want the basking surface at 30–32°C and the cool end no lower than 18°C overnight. Don't rely on the stick-on dial thermometers that come bundled with starter kits — they're consistently inaccurate and have caused real harm. A probe thermometer is non-negotiable.

That's the one. Search for 'Arcadia T5 UVB Kit 6% 24 inch' on Amazon UK — it typically comes up as the Arcadia ProT5 Kit. Make sure you're selecting 6%, not 12% (that's for desert species like leopard tortoises and would be too intense for a Hermann). Add a 50W halogen bulb and a digital probe thermometer and you've got everything you need, done properly, within your budget. The T5 tube will need replacing every 12 months even if it's still producing visible light, because UVB output drops before the light itself fails — just add it to your calendar now.
