PetPal Gear Score

Synthesized from veterinary references (Merck Veterinary Manual, ARAV, LafeberVet), peer-reviewed lighting research (Journal of Zoo and Aquarium Research UV-Tool, Frances Baines / UV Guide UK), and manufacturer-technical documentation (Arcadia Reptile, Zoo Med Laboratories, Exo Terra). The PetPal Gear Score is a composite of expert opinion, not a measurement - PetPalHQ does not run a testing lab.

Heat quality and burn safety together. Halogen lamps score higher for their larger IR-A fraction, which penetrates deeper into tissue and more closely mimics sunlight than a standard incandescent. Safety credit goes to wide, even basking zones over scorching pinpoints, to bulbs that pair with a deep-dome recess, and to setups that demand a dimming thermostat rather than an on/off controller.

Whether the fixture uses a ceramic socket rated above the bulb's wattage, whether a deep-dome reflector fully recesses the bulb to prevent climbing burns, and how cleanly the product pairs with a dimming thermostat. Bulbs are judged on socket fit and the fixtures they require; fixtures are judged on socket rating, recess depth, and built-in controls.

Cost across realistic service life, not just sticker price. A cheaper incandescent that burns out faster can cost more over a year than a halogen replaced once, and a fixture's value includes whether it saves a separate thermostat purchase. The best value puts money into heat quality and safe control, the parts that protect the animal.
