Our take

Diurnal reptiles need appropriate UVB, not just a warm glow. Zoo Med ReptiSun 5.0 is the long-running linear tube many keepers start with for tropical/temperate species at moderate distances. Pair with a fixture, measure distance, and replace bulbs yearly-ish even if they still light. Research your species' UVB needs.

Who it's for: Keepers setting up UVB for turtles, dragons, and other diurnal reptiles (species-dependent).

Skip if: Your species is strictly nocturnal with no UVB requirement — confirm care sheet first.

Pros

  • Widely documented UVB option
  • Standard T8 form factor
  • Brand keepers recognize

Cons

  • Needs a compatible hood/ballast
  • UVB decays before visible failure
