I'd go with the Arcadia instead since I'm assuming you're in the UK based off the link.
The bulb you linked to really hasn't been tested that I can find. Plus it doesnt appear that they give any output levels or distance recommendations which is a red flag to me. I'd stick to what we know works, and that's the Arcadia tubes. Or the reptisun tubes if you can get them on that side of the pond.
RED FLAGS
* T8 tubes .
* No distance to basking spot guidance or information on microW UVB / sqcm , mW UVA / sq.cm or UV-Index over distance.
* No indication of the UV spectral output.
I'd not use them at all in any reptile tank for ANY SPECIES reptile.
No - NOT SUITABLE and likely a dodgy brand and dodgy tubes with poor UV spectrum.
Stick with Arcadia Reptile T8 or T5ho, Zoo Med T8 or T5ho , or Exo Terra 26W UVB200 compacts or T8.
Thanks for the information. I'm going to be upgrading my bearded dragons take within a month or two and I have already got a UVB setup for it from Arcadia. I purchased this one because it was the only one the store had at the time, unfortunately the new Arcadia system doesn't fit in his old tank so this will have to do until he gets upgraded. I have contacted the company for more information on the bulb and even linked to this post to see if they had any response about the quality of their product.
That's encouraging. Have you heard back from the manufacturer yet? As mentioned, it would be helpful to have access to their test results regarding UVB output in order to place the bulb at the proper distance. Assuming you have the 10% version, not the 5% version, I would set it at about 15-20cm above the main basking area until you have further information about the bulb. This is usually a good range with the T8s.
