While I believe I'm not overconcerned about the current "plague", these days I find quite useful disinfecting our entrance hall (dirty hand touched handles + wrapped things brought from a supermarket) a bit.
As discussed with another LG member via PMs, we came to the same conclusion - to prepare a "germicidal" lamp from a spare 125W MV lamp. (I've got several of them.)
That lamp made last week and already used several times looks
exactly the same like this one - made 6 years ago(!) - it's been extracted from the same uninteresting Polish Helios branded Chinese MV lamp.
It definitely produces ozone but I'm not sure if the UV-C range radiated is really the same as that by true germicidal lamps?
Wikipedia suggests it should be so.What I'm more concerned about is the bare arc tube (burner) exposed to dust, possibly to some insects etc. - while I avoid touching it (the trick known from handling halogen lamps) - shouldn't it be cleaned by pure alcohol from time to time? Or better not?
Thanks for sharing your tips and experience.
