Default WARNING - FAKE UVB lamps sold on eBay UK

Fake “UVB” compact fluorescent lamps on sale on eBay in the UK

I am writing to warn reptile keepers of the risk of buying fake UVB compact lamps over the internet. Over the last six months, I have been asked to test compact fluorescent lamps bought by three different tortoise owners, who had purchased them from three different English eBay traders advertising them as 5% UVB bulbs for reptiles. Two of them were purchased as part of a tortoise table “kit”.
Suspicions were first aroused because they all have bayonet fittings. All current reptile UVB lamp manufacturers put E27 screw fittings on their lamps.
I have made the “poster” below from my photographs of these lamps, helping you to identify these fake UVB lamps. You are welcome to share this image freely. Below are more details and a summary of my test results. I have written a more detailed report which has been sent to Trading Standards and to REPTA but there seems to be little they can do to stop people doing this kind of thing. There may be other fakes out there, and it is really easy to buy very cheap household bulbs and re-sell them as “UVB lamps” so…caveat emptor!
SO PLEASE BUY ONLY WELL-KNOWN, HIGH QUALITY BRANDS for your animals. UV lamps are health products not décor. (And compact lamps, by the way, are rarely suitable for basking species except in tiny terrariums- but that’s a different story altogether..)


Type 1:
A 20W coiled compact fluorescent bulb with a bayonet fitting. There appeared to have been some sort of scrape over the manufacturer’s imprint erasing what would have been the brand name, and a clumsy overprint stating “5% UVB”. An internet search of the still legible lamp code “YPZ-US-20W” revealed that this lamp appears to be the following product, widely sold as a human “SAD” lamp: ‘Green Lamp 6400k Cool White’ energy-saving bulb. These are certainly not UVB lamps!
Green Lamp YPZ-US-20W B22 20 Watt 6400k Compact Fluorescent Light Energy Saving Bulb also for Treating SAD, Cool White: Amazon.co.uk: Lighting
However, this lamp was sold as an unbranded product with an information sheet stating, among other things:
“UVB output. Effective up to 30cm (12”). Provides necessary UVB rays for optimal calcium metabolism”, “..has a moderate to high UVB output” and “Ideal for desert and other UVB requirement reptiles”. I tested one of these (Lamp 1 in the table below).

Type 2:
These are 9V miniature coiled compact lamps with a bayonet fitting. An area under the imprint stating the lamp specifications had been scraped, erasing what would have been the brand name and making the origin untraceable. On the reverse side, a faint amateur hand-stamped overprint reads: “UVB Specialist UV”. No information leaflet was supplied. I tested two of these, bought by two different people at different times (Lamps 2 and 3 in the table below).

Test Results
Recordings consisted of:
• Total UVB 280-320nm (Solarmeter 6.2 broadband UVB meter)
• UV Index (UVB in the biologically active range of wavelengths) (Solarmeter 6.5 UV Index meter)
• Spectrograms (Ocean Optics Inc. USB2000+ spectral radiometer with a UV-B compatible fibre-optic sensor with cosine adaptor)

Meter readings
The results, after 30 min warm-up time, are shown in Tables 1 and 2. For comparison, test results from a new, miniature 13watt UVB compact lamp of a well-known brand, a ZooMed ReptiSun 5.0 UVB mini compact fluorescent, designed to enable vitamin D synthesis in reptile skin, are also shown. This lamp has a good spectrum for vitamin D synthesis but it is not a powerful UVB emitter, in fact I would say that this miniature bulb is probably suitable only for very small vivaria.


These readings show that lamp 1 is not emitting any UVB at all. Lamps 2 and 3 are emitting very small amounts of UVB at extremely close range. This is not an unusual finding for cheap brands of household compact lamps sold for human lighting, but these amounts are of no practical use.
For vitamin D3 synthesis to be possible, the UVB provided must include shorter wavelength UVB. The UV Index provides an indication of the intensity of the UVB in these shorter wavelengths. The meter gave zero readings at all distances greater than 10cm for all three lamps.

Spectral Analysis.
The full UV spectra of the three lamps, and for comparison, the ZooMed Reptisun 5.0 lamp, are shown below:


This confirms the meter readings.
The ZooMed lamp is emitting UVB and UVA from 295nm to about 380nm, owing to a UV-emitting phosphor. This spectrum is fairly typical of UVB-emitting fluorescent lamps designed for reptiles.
The other lamps show no evidence of a UV-emitting phosphor at all. The characteristic “spikes” are low-level UV generated by the mercury vapour; these are produced by all fluorescent lamps. Coatings to block them are sometimes applied to the glass; lamp 1 appears to have some coatings since there is only one tiny UVA “spike”, at 365nm.
All genuine UVB fluorescent lamps must contain a UVB-emitting phosphor, such as the one in the ZooMed lamp shown here.

Conclusion
It is obvious that these are not UVB lamps.
They appear to be household fluorescent lamps being fraudulently marketed as UVB lamps.
In my opinion, these are totally unsuitable for use as reptile UVB lamps. When used in a vivarium or over a tortoise table, they will not enable adequate vitamin D3 synthesis. If unsuspecting customers use these as the sole source of UVB for tortoises and lizards, I believe their pets are at risk of developing life-threatening vitamin D3 deficiencies including metabolic bone disease (the human equivalent being rickets).

Author's note
I believe this equipment and these methods are producing reliable and repeatable results which have scientific validity, but I would encourage professional laboratory testing of these lamps to confirm my findings.
Comments in this report reflect my personal opinions only.

Seeing these all too often in the £60 ebay specials, When we as a retailer try to explain that the customer has been ripped off and now they need to spend £20 - £30 on a proper UVB bulb..... Its not always met with enthusiasm, Lets hope we can spread awareness and get these stopped once and for all.

Thanks Neil.
That's why I've made this post.
Please feel free to share it. I've also made the "poster" as an A4 printable version, but it is 2.5MB so I'd have to email it to anyone who wants a copy. PM me with your email address if you'd like one.

These should be viewed as medical devices and regulated accordingly.

Presently anyone with a bit if money and a quarter of a brain can import UV lamps not to mention the fraudsters. These are life support systems and we have a duty as brands to ensure that we do the best that we can to cause life to flourish.

Ebay will delist the seller if reported with proof.

Default More fake lamps: screw thread as well

I just heard from two different sources that there are also fake UVB compact lamps being sold by the same eBay traders (household lamps being passed off as UV lamps) which have SCREW THREADS like our proper UVB lamps.
These, like the other fakes, also have scratched-out original labels overprinted with a rubber stamp. They may also be the typical "human" lamp wattages, rather than the ones used by reptile lamp manufacturers - almost all reptile compact lamps are either 13watt, 23watt or 26watt.
I'm waiting to receive more information about these. If I can test some, I'll post the results here.
