UVB Fluorescent Lights, Mercury Vapor Bulbs

UVB Fluorescent Lights and Mercury Vapor Bulbs are where you choose the UVB source for your reptile or amphibian. This category points you toward long fluorescent tubes, compact/LED UVB bulbs, and high-output mercury vapor and metal halide lamps so you can match your lighting to enclosure size, fixture type, and how much heat you want from the bulb. It’s especially useful for UVB-dependent species like bearded dragons, uromastyx, tortoises, and other basking reptiles that rely on UVB for healthy calcium use and bone strength.

From here, you can click into fluorescent linear tube UVB bulbs, compact fluorescent UVB bulbs & LED bulbs, or mercury vapor UVB bulbs & metal halide UVB bulbs. Use long tubes when you want an even UVB “curtain” across part of the tank, compacts/LEDs for smaller enclosures or tight spaces, and all-in-one lamps when you want heat, UVA, and UVB from a single bulb. Make sure you pair tubes and compacts with the right light fixtures, and consider appropriate reptile calcium & vitamins to round out your setup.

Choosing UVB Quickly

  • By habitat: Forest/tropical species often use 5.0-style tubes; desert species and other high-UV reptiles are better suited to 10.0 or high-output options.
  • By enclosure size: Short tubes and compact/LED bulbs work for small tanks; longer tubes and high-output lamps are better for larger or taller enclosures.
  • By heat vs. no heat: Choose fluorescent/compact UVB bulbs if you already have a separate heat source; choose mercury vapor or metal halide bulbs if you want combined heat and UVB in one lamp.
  • By hardware: Match T8/T5 tubes to compatible strip fixtures, and use proper dome or specialty fixtures for screw-in and HID lamps.
