Manufactured in Germany, it delivers sustained UVA and UVB output rated for 12 or more months, making it a reliable choice for keepers who don't want to second-guess their UV provision between bulb changes.\u003c\/p\u003e\u003ch3\u003eWhat the Mesophotic Zone means for your setup\u003c\/h3\u003e\u003cp\u003eSpecies adapted to dappled or partial sunlight have evolved precise basking behaviours — moving in and out of UV exposure to regulate both body temperature and D3 synthesis. The UVB200 VHO is calibrated to serve that niche, producing an intense output that varies with distance from the basking site, giving these animals the gradient they need to self-regulate effectively.\u003c\/p\u003e\u003ch3\u003eUVA, UVB, and visible light in balance\u003c\/h3\u003e\u003cp\u003eThis tube produces a well-balanced visible light spectrum alongside its UV output. UVA stimulates natural behaviours including appetite, activity, and reproductive responses. UVB drives Vitamin D3 synthesis, which in turn supports calcium absorption and guards against Metabolic Bone Disease. The phosphor blend is formulated to replicate the solar UVB spectrum rather than simply hitting a percentage figure.\u003c\/p\u003e\u003ch3\u003eVery High Output — built for taller vivariums\u003c\/h3\u003e\u003cp\u003eAs a VHO T5 tube, this lamp produces UVA and UVB levels that exceed those of standard T8 bulbs and energy-efficient compact alternatives. Enhanced UVB penetration means it performs effectively at greater distances from the basking surface, making it suitable for taller terrariums or enclosures fitted with denser mesh screens that can reduce UV transmission.\u003c\/p\u003e\u003ch3\u003eKey features at a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e54W, 46-inch T5 VHO tube — manufactured in Germany\u003c\/li\u003e\n\u003cli\u003eUV output rated for 12+ months of lasting performance\u003c\/li\u003e\n\u003cli\u003eUnique phosphor blend replicates natural solar UVB\u003c\/li\u003e\n\u003cli\u003eBalanced UVA and UVB with a full visible light spectrum\u003c\/li\u003e\n\u003cli\u003eUVA supports appetite, activity, and reproductive behaviour\u003c\/li\u003e\n\u003cli\u003eUVB promotes Vitamin D3 synthesis and calcium absorption\u003c\/li\u003e\n\u003cli\u003eHelps prevent Metabolic Bone Disease\u003c\/li\u003e\n\u003cli\u003eSuperior UVB penetration for tall vivariums or dense-screen setups\u003c\/li\u003e\n\u003cli\u003eRecommended for use with a compatible T5 terrarium hood\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFor keepers housing Mesophotic Zone species who want consistent, long-lasting UV output without compromise, the ET Reptile UVB200 T5 VHO 54W delivers the output and longevity to support genuine animal welfare.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54147930751313,"sku":"LHR124","price":17.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/LHR124_1.jpg?v=1782597694","url":"https:\/\/viperia.co.uk\/products\/et-reptile-uvb200-t5-vho-54w-46-pt2429","provider":"Viperia UK","version":"1.0","type":"link"}
