Captive Reptile UV Light Requirements

Many captive reptiles suffer metabolic bone disease from inadequate UV-B lighting, a preventable welfare problem.

Key Facts

UV-B light enables reptiles to synthesize vitamin D3
Deficiency causes metabolic bone disease and deformities
Many reptile keepers underestimate UV-B requirements
High-quality UV-B bulbs must be replaced every 6-12 months

Welfare Considerations

Metabolic bone disease is painful and debilitating, causing bone fractures and muscle weakness. Proper UV lighting is a basic welfare requirement that is frequently overlooked due to cost or inadequate keeper education.

What You Can Do

Research species-specific UV-B needs before acquiring reptiles
Invest in high-quality UV-B bulbs from reputable brands
Use UV meters to verify lamp output
Consult reptile-specialist vets for lighting advice
