How to generate UVC light?
So I want to generate obscene amounts of UVC(about 260nm) lightwaves, in order to rapidly sterilize areas. Im talking like, when you turn this array on, you want to be wearing a welding hood and a lead shield over your groin(possibly a welding hood over your head too) It seems all these consumer air purifier things are anemic, overpriced, and fucking stupid. I want the light to have direct contact with surfaces, so an enclosed air intake with a UVC bulb isn't really an option.
UVC bulbs are available for fairly cheap, though I don't know what kind of fixture or power supply to use for them.
For example:

You know how a green laser is actually an IR laser with a filter to turn it green? Or how fluorescent bulbs are actually producing UV light that fluoresce another material in producing a visible wavelength? Is it possible to do the opposite to an ordinary bulb? Say for example, a high output halogen, heatlamp, or even an array of high-output CFL bulbs?
Then there is the LED option..But Im not really sure how many would be required, nor how to calculate it.

The stuff on this site is used inside air conditioners. They can easily work out side of them also.
If they are 120 volts you can modify them to work off a wall socket. Just dont look at them too long or you will sunburn your eyes.
Those things seem absurdly overpriced.
The website if linked was just to give you an idea of the product that would work the best for you.
Just wear pants. You don't need lead to block UV light. Gamma rays on the other hand...
Im already wearing pants. And it doesn't help to fulfill my requirement of UVC light.
I was talking about shielding. Anyway you can get fluorescent tubes that are just clear glass tubes without phosphor that produce UV light.
Bulbs are probably the route Im going to take. They are easy to find. Just finding a proper fixture/p-supply is difficult..
So I got my own ballast and a couple 60w 254nm bulbs from this place: http://www.atlantalightbulbs.com. Cost $200, vs $600. The only work to do was to attach a plug to the ballast and plug the bulbs in. Apparently it is a powerful enough unit to sterilize a 1000-4000sq ft building. So my 50sqft clean room should stay very clean indeed.
Well it wouldn't exactly be a clean room if it wasn't sterile, would it?
For undergoing tasks that a normal room is too unsanitary for, of course!
Such as...
Clever play on words.
But yes, he is right. 50sq ft is plenty of space. I've got an idea that will enable easy harvest of spores without fucking around with prints. It requires some very sterile conditions, though. Oyster mushrooms sell for as high as $25/lb fresh..Pretty good profit margin to be had.
