Review on Powerful UV-C Light Lamp Bulb with Ozone - Harnessing Germ-Killing Technology by Jerry Crist

Assemble a decontamination box from an old fridge. Use a timer and a little light seems to work well. I don't see any dead bacteria, but research online shows the process works. Of course I can smell ozone, so that's a good sign. The seller convinced me the most. My lightbulb burned out after a few weeks. (That's why I use a timer now). Anyway, I contacted them and they contacted me within a few hours. They said they would send me a full refund but I told them I would have preferred a new bulb to a refund. They jumped right into it and within 2 days I had a brand new complete block! Impressive service.
