Osram HgH 500 Medium Pressure Mercury Vapor Lamp

Very rare medium pressure mercury vapor lamp with aluminosilicate glass arc tube that was only produced in 1936 and discontinued in 1937 in favor of the high pressure Osram HgQ 500 with quarz glass arc tube and higher efficiency.

WOW!!! Medium pressure mercury lamp in a GLS shape? And low wattage at 140w? That must be dim, from what I understand medium pressure mercury lamps are only relatively efficient from about 250w and up. Very cool find!

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

It's not too bad. The lamp has a light emitting efficiency of 39Hlm/W (265W HgH 1000 had 42Hlm/W and was produced much longer). But the high pressure replacement HgQ 500 one year later had 46Hlm/W.

I'm looking for:

Osram L20W/39
Philips TL20W/27

Wow unglaublich, ich dachte mitteldruckquecksilblerlampen waren nür bis 150W gefertigd durch die britischen lampenherstellers, aber deutlich auch niedriger. Ein sehr schön ergänzung fur dein sammlung . Interessant das es hast A-vorm glaskolbe, vermütlich besteht er auch ein version mit leuchtstoff. Has du diese lampe in ein alte buch oder katalog gesehen um die lumenwerte zu finden? Die englisch MA 150W hatte nur 4800lm also 5280 deutsche Hlm, und dein mit 5500Hlm ist ziemlich gut für ein noch kleiner 140W model. Aber mit zu alt entladungslamlpen ist es schwierig zu weissen ob es geht uber die initial, 100std oder mittelwerte während lebensdauer.

So to run this lamp with proper specifications one need a special dedicated ballast for it? I guess that the 125W rating was not yet choosed as a standard back then and became standard with the first HPMV lamps?

It is difficult to find the exact specs for this lamp, 125W rating was introduced about the same time. But in the beginning there was far more standardisation between the manufacturers and I have the impression that the operating current may be same as the 125W (originally 120W), so only the lamp voltage is different. For sure it would be safe to run it on a 125W ballast, at worst it may be slightly under-run.

@James: Please write your comment in Englisch, the translation is horrible.
There wasn't a version with phosphor, only this clear version. The replacement HgQ 500 had frosted glass but was also without phosphor.
And there was a HgH 300 (90W, 3300Hlm) that also got replaced one year later with the high pressure quarz glass version HgQ 300 (75W, 3300Hlm).
It's not too difficult to find the specs in German literature:

It is already the 3 time that I see that the German gives problems with the translator. I think the translator has a lot to improve

What an incredible find, especially in such a great shape! I had no idea that Osram made low-wattage medium-pressure mercury vapor lamps.

The thin glass "straw" supporting the upper half of the arc frame from the bulb wall is also a technique one would be more accustomed to seeing in Osmium or Carbon filament lamps from 50 years before this was made...and so very fragile too...this would not travel well across the world....yes, I agree, one of the rarest lamps depicted on this site....on a par with the MAF/V or A-H2!


...and from Charlottenburg too .... "quadruple bonus points!"


Hey, Rigo! Only the rest of your life mate!

There's a greater chance both you and I will lie in a box before we get to touch one of these!

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

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


The above list, I believe now contains examples ALL the major variants of Medium Pressure Mercury Lamp Technology from all the major geographical realms and geopolitical powers of the World.

I apologize to any members who have posted any Medium Pressure, particularly MA/V's or A-H1's that I have not linked to...however the above list of links should allow most members to find most examples, particularly if used in conjunction with the "search" option.

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

Rigo: There was more than ten of them in that shop at 186 Nguyen Thai Binh Street in Saigon in 2001. That shop still sells lighting and is now visible on Google street view....under a different name though. I can't imagine any of the rest of those lamps survived and I still "kick my own bum" as to why I did not grab the lot at the time I saw them for the rest of etermity.

You do realize that Chinese member here, "Men Of God" also has one the same?!!
