with it being only approximately 1-1/2" in diameter and 3/4" deep, you could sink it in about half way..............shouldn't affect the air flow?
What would be cool, is to find one like that, that uses a watch battery or something, so you didn't have to deal with the cord.
Being a LED, should late a long time

Posted: Tue May 19, 2009 9:35 pmWhat I am now looking for is some florescent string or thread so that when I make that device I put a picture on a couple of days ago I can use the UV LED's and make them glow and be easier to see.
Haven't found any string yet.

Thanks,

I use strong UV (Hg) lamps as a source in order to align echelle spectrometer optics, after optical service. Because the echelle covers 190-800 nm, we use the visible Hg green wavelength at 546.07 nm as well as others. The green 546 line is easiest to see.
These particular lamps are short wavelength and will burn the eyes just like an arc welder. They also generate considerable ozone when running. In order to see the visible spectra, the room must be almost completely darkened -- even with the intense Hg lamp as a source.
I am wondering if the lower power longer wavelength (safe) UV LED will have sufficient energy to fluoresce the string while you still have enough light to see the port?

Posted: Wed May 20, 2009 12:59 pmScott,
as much of a hassle it is turning out to be I think I will just get different colored string and use the regular bright white LEDs -
All I need to do is say "hey see how good it works" and then be blind 5 minutes later

Posted: Wed May 20, 2009 3:09 pmScott, Is there a way to determine wavelength "at home"? Not exact, just ballpark (i.e., blue is 400-600, ...). Thanks, Doug

Posted: Wed May 20, 2009 6:21 pmI want to try black light LEDs inside a clear valve/ valve stem made from acrylic. Light up the bowl and chamber a little more. It may not be strong enough though.
Posted: Wed May 20, 2009 9:47 pmjfholm here is a link to some glow in the dark string
That string might work hold a charge for 8-10 hours
they claim.
