The green "neon" lamps are actually argon glow lamps with green phosphor. I saw the spectrum of these green neon lamps and all that i found is the emission of the phosphor. Argon is the best noble gas to produce uv light at normal conditions (Negative glow), and xenon produce enough uv light only in high voltage (Xenon flash lamps) or high pressure (XBO short arc xenon lamps).

That is totally correct that they are argon lamps with the phosphor. they also available in other colors. I also have a bare argon lamp that gives off purplish glow!

Cool

Cool dude...makin' your own neon and CMH lamps.

Cool Lamp!...and where is the Homemade CMH?

Oh I never posted that homemade CMH...I personally showed it to Darren!

I remember this lamp of your own, it sure is really cool, is it bright?

Nice, I also remember this homemade lamp you had, if I recall correctly you reused the glass bulb from your homemade MV lamp.

That is awesome!

Btw, in Israel "Neon" is a common generic term for fluorescent lamps.

Very cool! How many watts is this altogether?
