Jin-Zhi 500w Chinese Medium Pressure Mercury Lamp. February 1965

Jin-Zhi 500w Chinese Medium Pressure Mercury Lamp. February 1965

This is the rarest of the rare because it combines both obsolete technology and unusual fringe geographical location of creation.

This was made about a year before Mao's "Red Guards" marauded around the country smashing the "four Olds"......well they missed this one!

Antique Chinese mercury lamp. Just unbelievable! Maybe they made tipped cage filament bulbs into the 1950s?

May all the great lighting technologies have their place in history.

Wow Andrew, what an incredible piece of lighting history! I never thought I would see this one day! You did a fantastic job saving it, there must not be too many of these around nowadays... even in China. The lamp is indeed very similar to its Soviet counterpart, the IGAR 500W, at the exception of the side ignition probe which is not present here. I wonder how they got the lamp started. Maybe like with the very first British MA lamps, i.e., with a small Tesla transformer inside the luminaire.

No ignition aid is shown in the circuit on the pamphlet from its box Max, so it is a real mystery to me too.

You know what irks me about this lamp! I shoulde'nt tell you this, but there were TEN of them in the shop at 96 Nguyen Thai Binh street in Sai Gon where I found it in 2001 about three months after the New York trade centre collapse....and very probably an IGAR 400 in there somewhere too....STUPIDLY I only took one...in hindsight I SHOULD HAVE GRABBED THE LOT!
I have been back to Sai Gon since and the shop has long gone...I do have some photographs taken inside the shop though, somewhere...but they are on chemical film/print paper, not digital.

The shop was simply AMAZING, every type of H.I.D. you could imagine, from every place you could imagine, I do remember a half phosphored BT-56 hanging from the ceiling amongst 200 odd other H.I.D. I also remember a Narva Wood's Glass 125w merc that slipped my grasp too. I only found the shop after I had been there six weeks and my money was nearly gone....had I found it when I arrived, I would have bought all its stock and got it shipped back here.

The only equivalent place I can think of that might still exist today might be in Pyongyang or Havana. When people are desperately poor, they will buy, sell and trade in anything that will fill their rice bowl at the end of the day....including E.O.L. lamps.....reminds you just how lucky we are in our "nice warm western countries". When you see it, right in front of you, it really brings back to you with a "slap in the face" what an unjust place this planet is and just how cruel some of us in this world can be.


Dave, when I was a little kid, I dreamed up all sorts of "Boogie Globes", ones with axial filaments, two arc tubes, two heat deflector discs stacked one atop another, black ones with no apparent purpose, fluorescent tubes in the shape of a "Y" with three caps......and, guess what! I reckon nearly ALL OF THEM are depicted here somewhere...their images hiding in the disk array of Patrick's server!

There was one former member in this site posted three arc tubes of SON in series in one envelope lit some time ago before you joined here. Due to his behaviour, he left the site with uploaded pictures removed by himself.

Pretty, please no more Chinese failure.

@rjluna2: You means IMJ?

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).

These Medium Pressures are so Iconic I have decided to link as many different examples on this site together so everyone can see which examples everyone else has...


American General Electric A-H1 400w, Hoboken, 1945

Rare German Osram HgH 500, (140w), Berlin, Charlottenberg, 1936

ANOTHER Jin-Zhi (Maoist Chinese) Medium Pressure, 500w, Bei-Jing 1965

Dutch Philips 57102G "MA/V" 400w, Eindhoven, 1955

British G.E.C.-Osram MA/V 400w, Shaw, Manchester, 1958

Very Early British G.E.C. "Osira" MA/V 400w, Shaw, Manchester, 1935

German Osram HgH 5000 "Bare Burner"

British Mazda B.T.H. "Mercra" MA/V-140, Rugby, 1935

German Osram HgH 1000, (265w), Berlin (Charlottenberg?) pre 1945

British Crompton MA/V 400, Guiseley, Yorkshire, 1960

Soviet Russia, State of the Union, Order of Lenin Electric Lamp Works, (M.E.L.Z.) IGAR-2 (500w) Moscow, (Preobrazhenskoye District), 1956

British, G.E.C.-Osram, MAF/V 400w, Manchester, (Shaw), 1955


I think this site now depicts all the major developments and examples from worldwide of Medium Pressure Mercury Lamp technology.

Sorry if every lamp is not represented, but the links above should place one close to many examples not directly linked above. Some very unusual and rare examples, notably the Chinese, Dutch, Soviet and German models may have gotten under the "Radar" due to not being known as MA/V's or A-H's

Manufactured articles should be made to be used, not made to be sold!

Thanks for digging these interesting lamps out from various members' galleries!
This 500w Chinese lamp is another beautiful lamp from before a time that price didn't make quality a race to the bottom.

My main area of interest is vintage fluorescent and mercury lamps. Always interested in doing lamp trades - just let me know! Smiley

This is DEFINITELY built up to a standard rather than down to a price.....unlike China after we got in there with all our "bad ideas" of deceitful marketing and churn.

Consider the socio-political goings-on at the place and time this was created....1965 in Bei-Jing, deep in the Mao Era and one year before the Cultural Re/Devolution where the teenagers under the "Gang of Four" went around smashing things....a vandal's paradise....somehow this lamp above and the one "Men Of God" has, made it through all that madness where China very nearly lobotomized itself.


Max makes the comment, above, that this is similar to an IGAR-2....I can re-iterate that it is nothing like an IGAR-2....the reflective coatings on the ends of the arc tube are different, the number of arc tube seals are different, the electrodes are different and the arc-frame is different also, they are as different from each other as an A-H1 is from a HO 2000!
