Factor breakdown

Expert Consensus

35%

Synthesized from veterinary references (Merck Veterinary Manual, VCA Animal Hospitals), peer-reviewed UV studies (Wageningen University & Research, Journal of Zoo and Aquarium Research), and manufacturer-technical documentation (Arcadia Reptile, Zoo Med Laboratories). The PetPal Gear Score is a composite of expert opinion — PetPalHQ does not run a testing lab.

Published UVI Delivery

25%

Whether the manufacturer publishes UVI-vs-distance figures for the lamp, and whether those figures match the species-appropriate target ranges in the LafeberVet UV-Tool reference and the Journal of Zoo and Aquarium Research UV-Tool paper.

Match to Species Need

20%

How well the lamp output class (desert vs. forest vs. all-in-one vs. compact) matches the microhabitat-and-basking-behavior framework in the source set.

Replacement Value

20%

Per-bulb cost across the manufacturer-recommended replacement interval, accounting for fixture compatibility and pack-size economics.
