Built around the Ferguson Zone 3 classification, this lamp is suited to keepers housing high-UV species that require strong UVB exposure to thrive. At 38W and 1050mm, it covers larger vivarium setups effectively, and should be positioned approximately 12 inches above the primary basking area for best results.\u003c\/p\u003e\u003ch3\u003eUVB Output and Vitamin D3 Synthesis\u003c\/h3\u003e\u003cp\u003eThis tube produces a UVI of 3.6, placing it firmly in the Ferguson Zone 3 range — the level of UV intensity experienced by heliothermic species that bask openly for extended periods. That output supports natural vitamin D3 synthesis, reducing dependency on dietary supplementation and contributing to long-term metabolic health. Replace the tube every six months to maintain effective UVB output, as UV production declines before visible light does.\u003c\/p\u003e\u003ch3\u003eFull Spectrum Performance\u003c\/h3\u003e\u003cp\u003eBeyond UVB, this is a full-spectrum lamp that renders natural colours and iridescence accurately within the vivarium. Correct light spectrum has a measurable influence on feeding response and breeding behaviour, making this relevant not just for physiology but for day-to-day animal activity and display.\u003c\/p\u003e\u003ch3\u003eSpecies Suited to Ferguson Zone 3\u003c\/h3\u003e\u003cp\u003eThis tube is appropriate for a wide range of popular and specialist species that occupy open, sun-exposed habitats.

Animals self-regulate UV exposure given the opportunity — denying that choice creates stress and risks overexposure. A well-designed UV gradient, with this tube at one end and a shaded retreat at the other, is the correct approach.\u003c\/p\u003e\u003cp\u003eFor keepers housing Ferguson Zone 3 species who want a reliable, correctly spec'd T8 tube in a size that suits larger enclosures, the RS Zone 3 T8 1050mm (42\") 38W is a straightforward, well-defined choice backed by sound UVB science.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54148079485265,"sku":"LRE142","price":17.32,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/LRE142_1.jpg?v=1782598602","url":"https:\/\/viperia.co.uk\/products\/rs-zone-3-t8-1050mm-42-38w","provider":"Viperia UK","version":"1.0","type":"link"}
