I built UVB luminary in 2008. Pity I didnĀ“t know about this forum so I could share.
I built half body luminary UVB narowband.
I used 3 lamps PL-L 36W/01/4P 1CT

I bought them in Germany
http://www.sglux.de/index.php?id=22&L=1&tx_ttproducts_pi1[cat]=19
It was 221 EUR + bank charges
The luminary I bought in Czech Republic. It is an ordinary ceiling luminary for 3 pieces 2xT16 bulb, cap base 2G11
Like this one

I bought an aluminium polish design so all the rays reflect.

There is no need to buy any balast. Just a cable and a chocolate.
If you build lamp like that, please, keep in mind that the rays are extra strong and first time you are not supposed to spend in front of the lamp
more than 40 SECONDS!
I still have the lamp and it works very well so if you like to see some pictures, let me know.
Yep, and the costs
lamps: 221 EUR
bank charges: about 30 EUR
luminary: about 65 EUR
cable: about 2 EUR
TOTAL: something about 318 EUR
Hope you like it

BTW I wonder if anyone here can actually SEE near-UV light of 300-315 nm wavelength? I am sure that at least some people can see violet light somewhat
shorter than 400 nm. Bees and other insects are supposed to be able to see well into the UV. |
I read some years ago that artificial replacement lenses used in cataract surgery were UV-transparent, and that people who had undergone that surgery
were actually used in some military operations, since they could see UV signals that were otherwise invisible. I don't know whether the story was
true. I'd like to think that materials science has advanced enough to give us UV-blocking replacement lenses, but I don't know that, either.
Even if your retina is sensitive to UV light, though, the resolution would be terrible. Even blue and violet light doesn't get focused very well by
the human eye, and UV would presumably be focused even more poorly. |
I have a UV lamp (MagnaFlux?) used to check metal castings for cracks. it has a big ballast and when it gets 'warmed up' even being in the beam of the
hand held 'spotlight' will make the lens or some part of your eye fluoresce. Even without looking at the bulb, your whole field of vision glows blue.
It appears like the air in front of you is glowing. Needless to say, this is not good for you or your eyes.
