Hi:

Sandy King had posted a message that someone is manufacturing a black
light blue (blb) compact flourescent tube - This is a flourescent tube
that screws into an incandescent light fixture.

See http://www.starmgc.com/blcklt.html

Item# F-60U Only $16.95 ea.

At this price it may be more expensive than using a standard straight bl
flourescent tube. It seems to be about the same cost as a four foot
flourescent bl tube.

I think the trick to making a UV printing with these tubes is setting up a
set sockets with the proper spacing to provide even lighting. I doubt
that anyone has tried this yet - This is a fairly new product.

I would look at the cost per unit area illuminated. I don't think these
would illuminate an area as large as a 4 ft flourescent tube.

But - if one was interested in testing a compact flourescent UV printer I
would try bolting four incandescent fixtures to a sheet of pegboard
(carefull with the wiring) The pegboard would allow you to easily change
the spacing of the fixtures - could use regular compact flourescent tubes
and a light meter to see if the illumination is even. Or use the compact
flourescnet blb tubes and do a bunch of test strips.

It might be cheaper to make a small UV printer with these compact
flourescent blb tubes. Smaller flourescent tubes and fixtures are often
more expensive that 4 ft tubes and fixtures.
