MELZ 1000w mercury vapor lamp

MELZ 1000w mercury vapor lamp

Click to view full size image

Here's an NOS Soviet mercury lamp. Electrically I believe it is equivalent to our less common H-34 lamps which operate at 130v and 8A. Made in 1985 but looks 1950s. Has two starting resistors, they are square rather than round.

Yup, it was an eBay find. Came here perfect!

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

It appears to be shaped sort of like an egg, LOL. Neat find!

Pride and quality workmanship should lie behind manufacturing, not greed.

This looks a cool and unique Lamp, being 130 volt 8 amps it would be ideal for use on the European Mercury/Metal Halide Ballasts,

Is there Roman numerals on the etch at the cap besides the year etch?

Pretty, please no more Chinese failure.

@ace100w120v, the phosphor looks slightly grainy. Kinda like the older Tungsram mercury lamps made in Hungary, 1980s and earlier.

They still use mercs in some parts of Russia, I see large swathes of them when I sit down and watch the monthly Russian road rage and car crash vids on YouTube. Entire highways lit by mercs in some parts.

@ace, I have not lit it yet, but I know it is the common modern yttrium vanadate phosphor, also known as /DX.

Very cool lamp. The Soviets were indeed rather technologically stunted in the latter half of the 20th century, continuing to use technologies and manufacturing processes from the 1950s and 60s well into the 1990s. For example, in the 1990s they were still making calculators that used LED and VFD displays, and building electronics which used vacuum tubes. Although I once read that they continued to use vacuum tubes because they discovered they were less susceptible to interference from radiation (from ie. a nuclear explosion) than transistors.

It was all in the 90 years of the twentieth. Now Russia uses the most advanced technology and it has greatly transformed over the last 15-20 years!

Cool lamp, I want to get one, too! And yes they are same specs as H-34, designed to run on a simple choke ballast off 240 volts, while simple choke ballasts for 250 volt H-36 must be 480 volt, and yes they exist---I have an OV-50 and 4 L-M/McGraw Edison Unistyle 1000 units with 480 volt simple choke ballasts. They use H-36 obviously. The H-34 are also less efficient than the high voltage H-36 and have shorter, fatter arc tubes, so the lower current density reduces efficiency. I also have and use Russian made vacuum tubes, mostly 12AX7 pre amp tubes, in my amplifiers sometimes. They are excellent tubes!

No. MELZ writed roman numerals in date only before end of 70's.

Naturally. This lamp is also produced in the 80's. In high power lamps MELZ was used only the phosphor with a red ratio of 10.

You probably don't know the story well.
Firstly, in the 90's the Soviet Union no longer existed. It broke up in 1991.
For this reason, we could not produce anything ourselves in the 90s, as there was a great economic decline. The factories were ravaged.
Secondly, sorry for the comparison, if Canada was economically devastated by the Second World War from the attack on her of Hitler's Germany, just as it was with Russia, it would also have lagged behind in the development of technology for ~ 20 years.

These lamps are designed to operate throгgh choke at 220 volts. I do not know how much their service life will deteriorate when working from increased voltage.

The devastation brought about by the second world war cannot be the only factor resulting in the USSR lagging in technology development for over 50 years! You also have to add the ruling of a brutal dictator (and of other less brutal dictators after 1953), and a political/social system that stifled technological innovation, personal development/initiatives and competition (beside causing way more deaths and population damages/distress than WW2 alone). Look at Germany for instance, this smaller country was also devastated by WW2, especially since it lost the war... This did not stop the Germans from picking themselves up very quickly during the 60s and 70s and eventually take the lead in lighting technology developments (the Western part of the country, that is... because the Soviet-controlled Eastern part did not really shine).
So please, don't try to feed us with some "Pravda" propaganda that WW2 was the single and only problem causing all of USSR's ills and backwardness. As much as I respect Russia and its people, the idea that WW2 was the main problem in the country's modern history is just an insult to anyone's intelligence.

This is an interesting political question. And I do not think that it is appropriate to describe it here. But if you want ...
"Tyrant" or "Dictator", about which you write, in just 30 years take Russia in sandals and poverty, and transferred the country with an atomic bomb and a raised economy.
What tyrants do you write about after 1953?
Were they tyrants in fact? These were political puppets.
The suppression of technical innovations that you are writing about was applicable in private, but technical innovations were not at all suppressed and, moreover, were welcomed when it came to benefits for the whole country and for all people of the USSR.
With this, industrial cooperatives existed constantly in the country as well.
Now, as for your words about repression and persecution...
For all the years of the "tyrant" rule, about 4 million people fell victim to them, while the losses of the USSR population from the Second World War only among military personnel are estimated at 19 million people not to mention the civilians. And this is only by the most modest estimates.
You also mentioned the rapid growth of the economy in West Germany...
Let us just remember the famous "Marshall Plan" without further ado. Let us remember who helped to West Germany and who made a big bet on its market based solely on their own selfish motives. Without this helper of West Germany, even her wise Chancellor would not have helped. However, we must pay tribute - this important player did not lose, and even won.
It is also not clear to me your mention of the modern period in the history of the my country, whereas my talk was about the post-war period. Why do you jump now, I do not understand? Today, Russia has quite comfortable living conditions and a developed level of scientific technical progress.
In conclusion, I want to note that with the obvious backwardness of the USSR in the sphere of scientific technical progress after the war, with which I rightly agree, I consider it completely incorrect to mention this with superiority tone, as a member did the "themaritimegirl". And, as a true patriot of my country, I will defend its achievements. I'm not trying to feed you propaganda from "Pravda". I have no benefit from this. I have been living without the USSR for almost thirty years and can look at things soberly.
Moreover, in your opinion, do you think it is correct to conduct such a conversation, if you were not a citizen of the country, did not know the full depth of its nuances in the past, and all the more do not know now?
Excuse me, but with all due respect, I will use your formula. Is just an insult for my intellect.
