Want to know which UVB bulbs our reptiles use?

We often get asked which bulbs we would recommend.

Without fail we give the same reply.

There is a really good reason for that, but it’s occurred to me that i’ve never explained why. So in an effort to help you make an informed decision when replacing your UVB bulb, i’m going to explain how we came to favour one particular bulbs over all the others. Then i’m going to tell you what that bulb is.

panther_chameleon.jpgYou’ve no doubt noticed that each UV bulb we sell has a different rating. Most commonly 5 or 10%. Different animals require different UVB levels depending on their natural environment. Most commonly, people keep desert animals such as Bearded Dragons which are heavily dependant on UVB. What a lot of people don’t realise is that even though the rating on 2 different makes of bulb would be 10% the actual UVB output can be very different.

Now, a good amount of UVB output is vital to keep your pet healthy. Since we breed our own animals we knew we needed to be getting maximum UVB from our bulbs. So a few years ago we invested in a Radiometer which would allows us to test the output of a few different bulbs (it also tells us if the bulb is tired and needs replacing way before our pets start to suffer).


So we set up a few vivs with the leading brands of bulbs and ran the test. The absolute winner, producing more UVB that all of the other bulbs was the Zoo Med Reptisun.

The truth is, this test isn’t exactly new. The guys over at UV Guide UK ran that same test a few years ago. If you have a spare 20 minutes it’s well worth having a read of their reuslts.

What do you think? Are there any other bulbs you guys trust?

Please remember that some animals may only require low exposure to UVB so always do your research first or consult a trusted expert.

    Hi Gary

    How do these compare to the Exo-Terra Repti Glo? I’ve been using them for less than a year and they seem OK.

    Should i swap?

      Hi Rob, the Exo Terra Repti Glo are a very popular bulb as they are a good price. From the tests I’ve done I would recommend paying the extra for the Zoo Med Repti Sun tubes. If your bulb is nearly a year old it will need renewing now anyway.
