Hi Hugh,
Yes, quite true! I'd forgotten about that! and I'm with you on the
Altair's too. I have a pair still stashed in the garage. I've used my
lamp for erasing EPROMS for years, and recently for erasing PIC's.
And for others reading, just operate the lamp in a box, or in a spare
bathroom/photolab (I hang a warning sign on the door!). As has been
noted, it's dangerous to expose your eyes to the light, and no doubt
will also cause severe sunburns.

Actualy the germicidal lamp tube is made of quartz not glass and thats why
the cost so much.
Glass in general is not very transparent to UV.
Had mine since the days of th PROM burner for the Altair 8800.

Hi John,
What you want is called a "germicidal lamp". It is a clear glass
fluorescent lamp. Mine is about 14 inches long. I bought it and a
holder for about $20 (quite some time ago). Ask for one at an
electrical supply house.

I do not have a UV light source. I didn't buy one as I didn't want
to spend the money. Some of you have told me that you made a light
box. What types of lights/lamps work for exposure? I saw somewhere
that a blacklight works. Is this true?
<SNIP>
So please, if you could help me build a UV light source to expose
small PCB's, I would appreciate it.
Thanks
