Possibilty 1899-1901 Frosted Universal Brand Carbon Lamp

I found this in a socket on a shelf in an Antique store, and I didn't even look at the base since it was in the socket which came with the lamp when buying it. As I bought it took it to the car....When I unscrewed the lamp, what surprised me was the base design! Those I was told was pretty much pre-1900 lamp! Unfortunately it does not appear to work...

Carbon filaments lamps are obsolete and inefficient but it's one of the top ten most wanted lamps to add to my collection. Absolutely a cool find you got there. Some of these carbon filament have a absolute great life span! Here's one of them but this time it's clear. 109 years burn time! That's almost a MILLIONS hours! Let's see a modern lamp last that long.

I am definitely gonna make a trip to Livermore to see the lamp itself someday. You can be sure that I will have a good pic of the lamp posted here and GL.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

GL?? It's called GoL!

And yeah it is a great find...it has a broken filament but i actually had it power on twice just for a split second!

I call it GL cuz GoL sound like something you say after this happen.

Strange that this antique carbon filament lamp is frosted and don't have an exhaust tip on its top. I thought that all old carbon lamps for general lighting had it and have a clear finish. Only the modern carbon filament lamps for heating purpose don't have an exhaust tip like the tungsten filament lamps.
By the way, how there were carbon filament lamps that saw unlimited life if they have vaccum and the carbon filament evaporate rapidly at its temperature?

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

On incandescents the long life come with underdriving them - ordinary (assume good quality) 1000hour rated bulb would last about 100years, when operated at 50% of rated voltage (assume the filament evaporation as the only wear mechanism).
In the early days the manufacturing process was not able to keep tight tolerances, so quite often lamps were running at way higher (so last very short) or way lower temperature then designed. And some of those running at the lowest temperature, but otherwise well made, are the "century lasting" pieces surviving till today.
Actually such bulbs are defective by the lamp quality metrics (below limit light output) and today are rejected at the product line, but century ago sorting equipment able to do so automatically was out of reach for lamp production lines, so these lamps pass to the sale ans some of them are burning till today. And become very nice examples of the past technology and very valued collection pieces.

No more selfballasted c***

Dor123.....It does have exhaust tip on top...look carefully....its frosted tip...the reason you is because i took a pic of it at an angle...the lamp was kinda standing up.....(note the shadows) I wanted to have a great shot with this....but this lamp does have a tip if you look in enlarged picture by clicking on the pic above.......frosted lamps were rare in olden days but I believe they did exist...I saw the filament inside the lamp...its one of those old two BIG loop filament!

Outside frost, why not try the olive oil trick, a small patch apply the oil sparingly will make the frost clear to see the filament. Then wash it off and the frost comes back.

Interested in the history of electric lighting and incandescent in particular and neon glow lamps.
