I went to the TRW swap meet on Saturday, and picked up a 866 mercury vapor
rectifier. The thing has a 2.5V 5 amp filament. Good thing I had this large
transformer in my stash with a 2.1V tap. Needed less than 50V to light it
up, and get the emission up to get more than 50mA thru. Tube is rated
Much UV leak out do you think?

You read my mind - I would have thought that this was a real (not
imaginary) danger. Nearly all UV is absorbed by the front of your eyes,
causing corneal damage, cataracts macular degeneration.
I'd

Ordinary glass (i.e. the tube envelope) is opaque to UV. That's why UV
lamps have to be made out of quartz.
Don't break it, though!

UV covers a large wavelength range - from about 400nm to 10nm. It seems
that anything shorter than 300nm is regarded as not good for human eyes
and that normal soda glass absorbs a lot of that, leaving mostly UVA (long
wavelength UV or NUV/near UV) as radiation external to the envelope -

I wonder if it is the right UV light for a mineral lamp (compared to that laser
pen he carry's)
surround it with rocks and see if there is any greenium inside them
anyway the ticket here is to reflect the light off the rocks and see if there
is any absorbed and then reflected
Any kind of filter I can stick on this thing to block the UV ? Tinted
Acrylic ?

Okay, we'll surround it with the rocks at Gary's house. That way we'll only

The small QI/Halogen downlight globes come/came in a couple of styles one
with the small QI/Halogen lamp at the centre of the reflector and open at the
front; the other had a glass plate across the mouth / front of the reflector.
That glass is for UV reduction. Don't know if it is special

Fo a go-no go test you might look to see if the UV is strong enough to
illuminate anything with UV writing on it. UK currency notes and
European passports carry invisible (to the eye) markings that
Paint some of the white stuff on it from the inside of a fluorescent
tube, and you'll have a complicated white light bulb.
They made us wear safety glasses at my last place, they had a lot of
welding bays, and claimed that clear polycarb safety glasses spread
out the uv from a flash enough to
