For desert reptiles such as Bearded Dragons and Tortoises that are kept in vivariums, the Reptile Systems D3+ UV T5 Reptile Lamp is perfect for giving them the UVB light they need to generate the all-important Vitamin D3 they need to absorb calcium.

These have higher UV light output than most reptile strip lights – a healthy 12% UV, better simulating the natural light your reptile would have received in desert conditions, where foliage and cloud cover are limited and your reptile would bask in the full heat and UV light of the sun.
