Exo Terra Reptile UVB100 T5 VHO 8W 12" Tube (PT2380)

The ET Reptile UVB100 T5 VHO is an 8W, 12-inch Very High Output fluorescent tube designed specifically for cryptophotic reptiles, amphibians, and invertebrates — the shade-dwellers, nocturnal species, and crepuscular animals that require measured, lower-intensity UV rather than the intense basking-zone output suited to desert species. Manufactured in Germany, it delivers a rated UV output lifespan of 12 months or more.

Designed for Cryptophotic Species

Animals that inhabit shaded forest floors, rock crevices, and leaf litter have evolved to receive UV indirectly — through dappled canopy light or reflected surfaces. This tube targets that biological niche, providing UVA and UVB at levels appropriate for species that actively avoid direct solar exposure. Nocturnal geckos, many amphibians, and invertebrates kept in bioactive terrariums are all well suited to this output level.

UVB That Works

• Very High Output (VHO) T5 format surpasses the UVA and UVB output of standard T8 tubes and compact energy-saving alternatives
• Enhanced UVB penetration makes it effective in taller terrariums or enclosures fitted with mesh screens that would otherwise block a proportion of UV
• Unique phosphor blend replicates the solar UVB spectrum rather than producing a narrow artificial peak
• Supports healthy Vitamin D3 synthesis, which in turn drives effective calcium absorption and helps guard against Metabolic Bone Disease
• UVA component supports appetite, general activity levels, and reproductive behaviour

Visible Light Spectrum

As well as its UV output, this tube produces a balanced visible light spectrum that complements the natural appearance of vivarium plants, hides, and the animals themselves. It is not a dedicated grow light or a purely functional UV source — the light quality contributes to a well-lit, naturalistic setup.
