Soviet 1Kw lamps

Soviet 1Kw lamps

Click to view full size image

Got both from my grandpa. The darkened, heavily used one on the left is used by my grandpa, when he was working with photos. It is actually 750 watts. The NOS one on the right is 1000 watts. I have 4 more of these 1000 watt lamps. All NOS. I really like how large the envelope is, compared to regular mogul e40 base. The filament design looks funny too. I actually use these 1kw lamps two in series as a ballast for my 700 watt soviet MV lamp, when I'm in a mood for experiments. I don't have 700 watt MV ballast and two of these 1kw lamps in parallel and in series of a 700 watt lamp creates a perfect ballast for it. What was the intended use for these lamps in USSR I don't know, would be nice to know.

Possibly for floodlighting, they are still used for that purpose in some places I think. I do love big incandescent lamps, there is something special about them

Interesting to learn that you use them to ballast a 700W MV lamp, I will have to try that..!

yep. I was thinking to myself 4 years ago: "How to turn on the 700 watt mv lamp? Wait a minute. If self ballasted mercury vapor lamp uses 110 watt filament and 50 watt mercury vapor tube, then 2 kw incandescent lamp would be good for 700 watt mv lamp!" I made my setup, checked it 10 times to see if there is no shorts, and I remember that I was very hesitant to plug it into a socket, because I was afraid of a loud bang and glass all over me and the room. But I plugged in the socket, immediately crawled into a ball and prayed for a few seconds. Nothing exploded and to this day I use various wattage incandescent lamps to power up for testing 125, 250, 400 etc mv lamps, because I don't have ballasts for them.

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
We shall reinforce ourselves with good old full mercury t12s and HIDs made to surpass one's life, and give them all the middle finger ;

They remind me of the RAZNO brand. Its construction is similar. They were used for industry also in theaters

That's interesting, thanks. I think that the only lamps I have that I don't have ballasts for are some HPS lamps, 100W, 250W and 400W. Of course the difference is they need an ignitor, so not sure if ballasting with incandescent lamps would work in the same way.

I have tried to turn on a 400 watt sodium lamp with igniter, using a kettle as a ballast. Sounds ridiculous, I know, but it worker fine, actually, when the lamp reached full brightness the kettle became look warm, because arc resistance wasn't enough to make water boil. With incandescent lamp I haven't tried igniter, will try some day soon.

I really do not understand much about discharge lamps. But better would be a ballast. It does not pay to spend a nice copy and risk melting the discharge lamp. That yes, for example, a bomb of 1000w of those Chinese. if it is spent, nothing happens.

Of course, dedicated ballast is always the way to go, but for just experiments you need a variac and a weak breaker. You'll be safe from explosions that way.

I have a Variac but it is only a small one, 2.5A maximum. I need a bigger one..!

I am thinking of buying a variak of 5kw I think it will be the next purchase. It is the best

Perhaps i can tell you something.
Today in Russia exactly such lamps has not been produced for a long time. After joining to the World Trade Organization, a series of formal rules required a ban on the turnover of incandescent lamps over 100 watts as inefficient and energy-intensive. Of course, they continued to produce them officially, but under the name "heat radiator". In addition, it should be borne in mind that incandescent lamps of similar power had already been considered an atavism and they were unprofitable when using them still before this event, so the quality requirements for their manufacture by the end of the first decade of the 00's become not so high. The bases and the size of the flask were subjected to simplification or reduction, the burning time did not correspond to the declared, their assembly was made in haste, etc.
But still in the 90's sometimes they could be seen in the mirror spotlights. Like the spotlights themselves. For example such:
http://www.electro.tomsk.ru/upload/iblock/407/4075d84c5bbeca838c393c2ebe1c9173.jpg
But in earlier years, these lamps were the main source of street lighting in many cities of USSR. For example, in similiar lanterns:
https://street-lighting.webnode.ru/ulichnye-svetilniki-v-sssr-1950-1990/podvesnye/szp-500-v-3/
or
https://street-lighting.webnode.ru/ulichnye-svetilniki-v-sssr-1950-1990/podvesnye/spo-1000-tip-2-/
Further, i would like to remind that RAZNO is not a brand. This is just a Soviet TradeMark of products intended for export. But firstly, under this brand were produced lamps of completely different factoryes, not connected with each other, and secondly, produced exactly the same lamps as for the domestic market. Just with the inscription RAZNO instead of the factory mark.
Also in early years USSR has been other TM. For example OREOL
https://street-lighting.webnode.ru/lampy/oreol/drl125/

And of course, not nothing surprising that incandescent lamps with active resistance can be used to start and work mercury lamps. Although according to some studies it is not as good for a mercury lamp as inductive resistance. Many manufacturers produce a line of lamps of mixed lighting and there is no difference where the filament will be - inside the overall flask or as a separate lamp. In any case, they are connected in series. The main thing is to right choose the power of filament.
But Daniel f is right - lamp, kettle, M.O.T. and other can be used, but is always better would has a ballast.
1000w is Ufa factory. I quarter 1975. Only this link, now is dead https://vk.com/club34241850
750w is Zaprudnevsk factory. I not see date. Prepares next links with el. translator has been interesting

Wow Gospodin! So much information thank you so much for it!!
