The best fixture that we’ve ever used for our reptiles’ UVB requirements! Now we are offering this great fixture in the 46” length model! This T5HO (high output) fixture gives superior performance because of its high output electronic ballast and its high-efficiency silver reflector. UVB is necessary for your reptile’s synthesis of vitamin D3, which is essential for the effective metabolism of dietary calcium in its bones and blood. The 46” model is perfect for oversized habitats greater than 36” in length. It is also useful for breeders that run their fixtures perpendicular across several plastic tub habitats.
