Shocked Scary things them! Apparently people have been buying them because they're dirt cheap and sticking them in normal fittings thinking they're normal lights.

LOL. I have grown to like PL-S lamps as of late

Might have to try one inside of a pint glass or something.

Try get lit pics if possible. Good opportunity to see the arc

I like these as you get a perfect view of their construction which is good for explaining to others how a fluorescent tube works. This reminds me that I need to get a new 36w PL-L UVC lamp ready for Spring to keep the pond algae free.

How is the lamp gettered from impurities without the help of the phosphor ?

very cool to see some osram ones, most of the ones I see are Philips ones, or Cheap china clones which use Quartz glass rather then Low ion content soda lime glass like these osram (and other name brand) ones do Smile

Surely quartz is best as that is completely transparent to UV...
Lightbulbfun   [21 Dec, 2018 at 07:28 PM]
apparently it can go a bit opaque over time when used in these applications, so the best is actually soda lime glass with most of the iron content removed (its the iron content that blocks short wave UV in normal glass) im sure James could fill in all the details I have missed Smile

Any chance of a close up of the electrodes Mark? Smile
