Anyone else collect unusual lights?

[photonaholic]

please do!

Some metal halide lamps with a 60W incandescent for scale. wattages are 50, 100, 175, 400, and 1000. The 100W and 400W have seen many thousands of hours of operation, so the arc tube is darkening. They still work fine, but with decreased light output.

And here are some high pressure sodium lamps. Wattages are 50, 70, and 1000.

And here is a 175W aquarium bulb running in a floor lamp. Color temp is 20,000K. What can I say? Sometimes I feel blue.

I still own my very first lava lamp. This thing is older than most of the people on the forum :bday:

Black Lights? How about 30 WATTS of SWUV?

i have a bunch of older vacuum tubes from radios somewhere.
got to find them.

To Dave or any of the other rock-hounds- anybody heard of a Mineralight?? made in South Pasadena Cal. like 50+yrs ago- UV 4 watt sylvania bulb----------- from Ultra-Violet Products Co.(no longer in biz) the housing for the bulb is either bakelite or old plastic-110vac ====says on the side DO NOT LOOK AT THE ULTRVIOLET LIGHT as rays will sunburn unprotected eyes' my best guess is that it is for looking at certain rock specimins-belongs in a rock-hound museum.----HZ

I have an old light bulb I found in Blue stone mine (yerington NV) It is THICK and looks like it would still work. But I wont clean it up to use, as It looks SWEET as it is.

IIRC it is a Short-Wave UV (~250nm) light.
It will show different fluorescence than Long-Wave UV (~350nm)

Most "entertainment" type black lights are Long Wave. Blu-ray lasers are NEAR UV. Short Wave UV is more damaging to eyes and skin. Your light is NOT dangerous unless you shine the light onto/into your eyes for a significant time. Even then the damage is more like "welder's flash" in that it causes a mild "sunburn" to the surface of the eye.

I have one of these as well. They come up on eBay every once in a while.

Peace,

I knew you'd know about it and prob have one too...any guess about its value--do you need a back-up one? LOL................. also what is it used for?? ..................................BTW I will send it to you free if you will finish my green module/Jasper host build. the module was removed from true 5mW from DX and needs a jump wire soldered over the push button and pot modded up a tad.

As with most vintage items, it depends on so many things: condition, model, rarity, etc. It could be anywhere from $0.00 to $100.

It is used in identifying minerals. Fluorescence and the color of that fluorescence is one of the indicators used in identifying an unknown specimen.

If you have no use for it, I would love to have it. I also collect old gemology and mineralogy tools.

I am willing to look at your laser for you as a service. If we need more than a solder jump for it to work, we will talk before I do anything.

I'll send you a PM with my address.

Have you snagged one of these? 400W mercury vapor lamp in woods glass. I don't think they make 'em any bigger than this.

Isn't that the bulb rock bands use in the cans??

I wondered how long before someone mentioned Geissler tubes.

First saw them in science class (physics) and wanted one or the whole set then. (1982) The school set was in a wooden box lined in plush felt.

The teacher hooked them up to a HV coil and demonstrated them, I was in awe.

A set would be worth every penny, and it would look awesome to have them all side by side in a plexiglass display box, all lit up at once.

Those are stunning!! Some very nice light sources here - I'm rather impressed!

I know they are used as "UV cannons," The DJ stores want $200-500 for a fixture when a $30 used ballast and a new $50 bulb will suffice.

Here's 1,500 watts of tungsten, 250V

Realy sweet pics.

Wow you guys have some awesome bulbs... I 've always been fascinated by incandescent lamps, ever since I was a young kid! Here are a few bulbs I have, nothing fancy or impressive as previously posted, but some unusual ones:

On top, a candelabra lamp that I've never seen before, right below, a small hard wire lamp (I have a bunch of these). Next, not a lamp per say but a magnesium flashbulb from the early 60's (I found a box of those at a flea market).

The lamp with the red block is a typical "telephone terminal" flange type... the one after is a bit mysterious, it's a highly reflective 12V car-type bulb... it lighs up a room I can tell you!!!

And then I have a dozen of these brand new never used mini UV neon tubes. I'll eventually figure out a project with these. Finally, I have a bunch of these brand new panel neon lamps in their original boxes (I just can't resist buying vintage new components).
