Argon Bulb
 
Just a neat little curio for nerds like me. These bulbs give off the familiar "purple" argon gas glow.

Not bright, but interesting

GE W1A / AR-1 Lamp. New, Old Stock. Original Box. EXC! | eBay

I am not affiliated with this seller or these auctions

Peace,
dave

These are interesting, I wonder what the original use for these were.

Thanks for sharing, this seller has some other neat things there.

Edit: Link for the bulbs...

The original use, same as for the "neon" orange ones, was as "night-light" illumination points ..... Ar ones was purple, instead orange like the Ne ones .....

Lots of time that i don't see them ..... i have in my collection some of the Ne ones, but no AR ..... they are impossible to find, here.

Here you can see a fun assembly which uses one of these old bulbs.

I discovered a while ago, and yes, is Useless but is fun :D

Here one video.

I love little curios like these as well, but the problem is, you look at the link, then think "wonder what else they have on the site"

Next thing you know an hour has passed and you coffee is cold.

Damn you.

EDIT

just seen piferal's pic/ video

Want one....NAO

Those are neat little bulbs. I don't think I've ever seen one before.

Are you sure? That sounds like a bad idea. As pointed out in a link, the life span is much much shorter than neon. The argon is accelerated by the electric potential and since it is heavier than neon, it sputters the electrodes more quickly.

Could this be used for calibration of my spectrometer?

It's not difficult to find spectral line graphics for Argon, but I haven't had any luck in googling for the actual numeric data (instead of pictorial representations shown on a simulated spectrum).

I used to have one of these as a night light when I was a kid. My grandfather, who was a chemist and also a woodcarver, carved a nightlight and put one of these in it. I never really asked where he got it from.

@ piferal: ROTFL at the "coachella lamp" :p :D

I know, but in the past, that was one of the use of them ..... the main use, in a certain period of time, cause probably it was more "cool" (regardless the high amount of UV emitted :p) than normal neon lamps (at least, til the introduction of the "green neon" :p night lamps :D).....

Also, before this, they was used as UV source for fluorescence, but i think that type of use lasted less (also if, probably, they was originally designed for this reason), cause the visible part interfer too much ..... i mean, for professional use .....

Anyway, i suppose that was an all-American thing ..... or, at least, here in Italy those lamps was (and still are) impossible to find ..... i collect from years all the "strange" lamps i can find, but never found one of them here, in the last 30 years at least :p

Daguin: do you think the Argon spectral lines would be distinct enough to use in calibrating a spectrometer?

Re: Argon Bulb
 
Is anybody in the US planning on buying one? I'd like to get one but I'll be out of the country for a while. I wouldn't want to take a chance on it getting broken while sitting in the post office. I'll send the money if somebody would be willing to hold it for me.

Sorry. This is beyond my knowledge base

I can pick up a couple of them to hold. I should probably hold a spare on-hand anyway

Peace,

Thanks. I'm already missing the beautiful color of my ArIon. I fired it up for about an hour a couple days before leaving. Hopefully that will hold it over for the few months I'll be gone.
