Exo Terra Reptile UVB300 T5 VHO 8W 12" Fluorescent Tube | PT2430

The ET Reptile UVB300 T5 VHO 8W 12" is a Very High Output fluorescent tube designed for reptiles that require intense, full-spectrum UV exposure — specifically those species that bask in open or midday sun, classified within the Euphotic or Heliophotic Zones. Manufactured in Germany to a high quality standard, this 8W T5 tube delivers a 12+ month UVB output lifespan, making it a dependable long-term option for keepers who take UV provision seriously.

Who This Tube Is For

This tube is built for heliophilic species — lizards, tortoises, and other reptiles that in the wild actively seek peak solar intensity to regulate body temperature and maximise UVB intake through basking behaviour. These animals need UV levels that standard T8 or energy-saving alternatives simply cannot deliver. The UVB300 VHO designation indicates an output intensity suited to replicating those high-UV environments within a vivarium or terrarium setup.

UVA and UVB Output

• Very High Output (VHO) UVA and UVB emissions exceed those of conventional T8 tubes and energy-efficient alternatives
• Unique phosphor blend replicates the solar UVB spectrum rather than approximating it
• UVA stimulates natural behaviours including appetite, activity levels, and reproductive behaviour
• UVB supports Vitamin D3 synthesis, which in turn drives calcium absorption and helps protect against Metabolic Bone Disease
• Enhanced UVB penetration makes this tube suitable for taller terrariums or enclosures fitted with denser mesh screens

Spectral Balance

Beyond raw UV output, the tube produces a well-balanced visible light spectrum that complements its UV emissions. The combination of UVA, UVB, and visible light works together to create a more complete and biologically relevant lighting environment, rather than simply ticking a UV box.
