Exo Terra Repti Glo 2.0 T8
Exo Terra Repti Glo 2.0 T8 is the most conservative UVB option in the list, intentionally very low-output to suit delicate amphibians and crepuscular reptiles that require minimal UVB. Its technical advantage is a gentler emission profile than the 5.0 and 6% products, which reduces risk of overexposure, but that lower output means closer placement and more careful husbandry compared with the higher-performing T5 options.

Arcadia's D3+ 12% T5 is positioned as a premium high-output fluorescent tube with a spectrum tuned to more closely mimic natural sunlight and enhance vitamin D3 synthesis, making it a top pick for species with higher UVB needs. It sits between Zoo Med's 10.0 and Arcadia's Dragon 14% in output, offering a strong technical advantage in spectral fidelity and consistency at a slightly higher price, and is preferred when spectrum quality and biological accuracy are prioritized over cost.

Zoo Med ReptiSun 10.0 Compact Fluorescent
The Zoo Med ReptiSun 10.0 Compact Fluorescent is a market staple for high-UVB requirements (desert-dwelling reptiles), notable for wide availability and competitive pricing that makes outfitting multiple enclosures economical. Relative to the Exo Terra and Arcadia offerings, its chief advantage is cost and ubiquity—while some keepers prefer Arcadia for spectral fidelity or Exo Terra UVB150 for greater penetration, ReptiSun 10.0 remains a go-to for budget-conscious high-UVB setups.

The ReptiSun T5 HO Terrarium Hood is a go-to choice for reptile and amphibian keepers who need high-output, even UVB coverage across larger enclosures; its reliable T5 high-output tubes deliver strong, consistent UVB at a lower upfront cost than some premium kits.
