NEPTONION T5 HO UVB 5.0 Reptile Replacement Tube, 8W 12 in Linear Fluorescent Lamp, for Rainforest Reptiles

【UVA + UVB Output】 Available in 5.0 and 10.0 UVB options. Helps reptiles synthesize vitamin D3 and support calcium metabolism when used with proper husbandry (distance, fixture, and species needs).

【Linear Coverage】 The linear T5 design helps provide more even coverage than point-source bulbs, improving usable basking-area coverage when matched to the right enclosure size.

【Daylight-Like Spectrum】 Supports natural behaviors like basking, feeding, and activity with a bright, clear light output.

【5.0 / 10.0 Options】 Choose 5.0 for many tropical/rainforest species needing lower UVB, or 10.0 for many arid species that require higher UVB. Always match output to species and distance guidelines.

【Optimized Fixture Match】 Use a NEPTONION T5 fixture/hood matched to your tube’s length + wattage. Each Tube is operation-tested and built for long life and high luminous efficacy. Other brands may cause fit issues and weaker performance.

【Quick Fixes】 If the tube flickers after turning on, make sure the two pins are fully inserted and twisted into the locked position. If it still flickers, the tube may be damaged—contact us and we’ll make it right fast.

【Maximize Performance】Built with premium ballast to ensure consistent output and extend the effective UVB lifespan to its true maximum, it also helps reduce tube flicker. PS : A light rattle may be heard when the lamp is gently shaken. It comes from a tiny metal parts that activates the phosphor to produce UVB light. This is normal and completely safe.
