Product Information

You can get a brighter UV output than a T8 lamp with an Arcadia D3 UV Reptile Lamp from Swell Reptiles - far more efficient than older models of fluorescent tube and with a 6% UV output, this model is perfect for rainforest reptiles such as chameleons, water dragons and crested geckos.

T5 tubes are the update from the older T8 fluorescent strip lights, using less energy than older models but giving you're a brighter more intense UV light for your reptile to benefit from. These 6% UV lights simulate the ultraviolet light from the sun, filtered by the rainforest canopy, giving your reptile a dose more accurately resembling what they would receive in the wild.

These Arcadia D3 Reptile lamps help your reptile generate vitamin D3 when they bask under it, allowing them to absorb the calcium in their diet and use it to build strong skeletons. This is an extremely important part of reptile keeping, and without D3 UV and calcium, your reptile can develop problems like Metabolic Bone Disease.


If you are keeping a desert reptile (E.G. bearded dragon, Uromastyx, Etc) we recommend the D3+ which gives 12% UV, but for rainforest reptiles this model is ideal, giving them just the right amount across the entire length of their reptile home.

Under this Arcadia UV strip light, your reptile will even look better! That's not only because they will feel healthier and more comfortable, but because the UV light brings out your reptile's natural colours, making many of them more vibrant than ever!

This reptile lamp should be positioned between 15 and 20cm above your reptile's head, giving them a good dose wherever they roam in their terrarium or vivarium.

The Arcadia D3 T5 6% UV Lamp comes in three different sizes to suit a variety of reptile setups:
