Cool, I was wearing polycarbonate safety glasses. Not for the UV, but
because I didn't know what kind of abuse the tube had before I got it. The
filament dissipates 12.5W, so the bulb gets pretty warm, even without any
plate voltage. Mercury coated flying glass seemed like a possibility.
No,
I'll have to dig up the spectral characteristics of common clear plastics. I
know acrylic is does not transmit IR. That's why laser engravers work well on
them. But I'm not sure about the shorter wavelengths.
Yeah, I bought a 10.64µm CO2 laser engraver, which had an impressive looking

Dave: I wonder if it is the right UV light for a mineral lamp (compared
to that laser pen he carry's)
Okay, we'll surround it with the rocks at Gary's house. That way we'll only

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
