Claude vs Mistral: Blue-tongue skink bioactive UV setup advice. Join the debate.: Arcadia ProT5 UVB Kit

Good setup to be thinking about early — bioactive and UV need to work together from day one or you end up retrofitting awkwardly. For a juvenile blue-tongue, you want a T5 HO UVB tube — the Arcadia Forest 6% is my starting point for a planted bioactive build. It gives you solid UVB without the intensity spike that can stress a young skink, and it plays nicely with live plants because it's not bleaching everything out. Pair it with an Arcadia jungle dawn LED bar for visible spectrum and plant growth — that combination is genuinely hard to beat for this kind of setup. The key question before I confirm that: what size is the enclosure, and is it open-topped or glass with a mesh lid? Both of those change the tube length and mounting position, which changes whether 6% is enough or whether you'd want 12%.

Good question — I was assuming mesh lid with the tube mounted on top, which typically puts the basking zone around 25–30cm from the tube. At that distance in a 4x2x2, the Arcadia Forest 6% gives you a UVI in the 2–3 range across the basking spot, which is right for a blue-tongue skink. If it's glass with a solid lid and the tube is inside the enclosure mounted higher up, that changes things — you'd want to confirm actual distance to the basking surface before settling on 6% vs 12%. For a standard 4x2x2 with mesh top and external mounting, I'd go with a 46-inch Arcadia Forest 6% T5 HO tube with the Arcadia ProT5 Unilamp controller — it's built for that enclosure width and the kit comes with everything needed to mount cleanly above mesh.

The UV tube itself doesn't meaningfully affect basking temperature either way — that's your basking bulb's job, kept separate. Mesh mounting slightly reduces UVB transmission (roughly 30% loss through mesh), but with the Arcadia Forest 6% at 25–30cm that still lands you in the right UVI range for a blue-tongue. It's a known variable Arcadia accounts for in their recommendations. So here's the final call: get the Arcadia ProT5 Kit 46 Inch with Forest 6% Tube. It's sized for a 4x2x2, mounts cleanly above mesh, delivers the right UVI at the right distance for a juvenile blue-tongue, and won't stress your plants or your skink. Pair it with an Arcadia Jungle Dawn LED Bar 36 Inch for plant growth and visible light. That combination is purpose-built for exactly what you're setting up. You won't need to revisit it.
