{"product_id":"rs-zone-1-t8-450mm-15w","title":"Reptile Systems Zone 1 T8 450mm 15W UVB Lamp for Reptiles \u0026 Amphibians","description":"\u003cp\u003eThe RS Zone 1 T8 450mm - 15W is a full-spectrum UVB fluorescent tube designed for crepuscular and low-light species — animals that are active at dusk and dawn, shelter frequently, or do not engage in prolonged basking behaviour. At 450mm and 15W, it fits standard T8 fixtures and delivers a measured 0.5 UVI output, placing it squarely in Ferguson Zone 1 — the appropriate range for species that receive only incidental or indirect UV exposure in the wild.\u003c\/p\u003e\u003ch3\u003eWhat Ferguson Zone 1 means in practice\u003c\/h3\u003e\u003cp\u003eFerguson Zones are a science-based framework for matching UVB output to a species' natural light exposure. Zone 1 covers animals that spend much of their time in shade, under cover, or in twilight conditions. The 0.5 UVI output of this lamp supports vitamin D3 synthesis at a level appropriate for these species without overexposing them. As a T8 lamp, positioning it approximately 12 inches from the most likely resting or basking spot is recommended, and the tube should be replaced every six months to maintain effective UVB output.\u003c\/p\u003e\u003ch3\u003eKeeper and animal benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e0.5 UVI output supports vitamin D3 synthesis in shade-dwelling and crepuscular species\u003c\/li\u003e\n\u003cli\u003eFull-spectrum output renders natural colours and iridescence accurately\u003c\/li\u003e\n\u003cli\u003eShown to support improved feeding and breeding behaviour\u003c\/li\u003e\n\u003cli\u003eSuitable for vivarium setups where shaded retreat areas are always provided\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecies this lamp is suited to\u003c\/h3\u003e\u003cp\u003eThis lamp is appropriate for a broad range of reptiles and amphibians kept in UK collections.
