WOW,just wow! I think it's like the 500w two electrode mercury vapor lamps used in Russia during the Soviet era?

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

My guess it is similar electrical design to SOX with leak ballast

Pretty, please no more Chinese failure.

Thanks for posting these close ups, Andrew. It's a real privilege to take a close look at such a rare artifact!

@ Dave - maybe, although the Soviet lamp had a quartz burner and it its driving circuit was provided with a series ignitor. This Chinese lamps starts in a different way for sure.

unbelievable find! I'd go with a hi ocv ballast, like they used with LPS. Now to track one down and find out.

Very interesting indeed! Most unusual to see a lamp like this with no starting electrodes.

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

CHINESE medium pressure MV?!?!? I didn't know Chinese was in the medium pressure MV club.

How long did these last for? 5 hours? J/K. I know the Chinese know how to make quality stuff. Sylvania MV lamps and so on.

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.

The reason why most stuff from China nowadays is crap is because they are building to a price. People want cheap cheap cheap nowadays, so everything is crap!

Linear fluorescent will never lose to LED!
I am not Anti-LED, as I have some in use at my house.

Interesting to hear all of your reactions. It does not use a high OCV leak-transformer, just a series choke and P.F.C. Capacitor.....look at my post oof the pamphlet that was in the packet with it.

It does not start however...not even on a "neon sign transformer", (where it just arcs in the outer nitrogen fill right at the press. I suspect argon sorbtion or hydrogen poisoning.

One day I might try to "eddy current it up" with R.F. induction but it won't be anytime soon.

UPDATE....Google Street View is RAPIDLY EXPANDING across Saigon where I got this lamp...it is now possible to reveal the shop where I purchased this...196 Nguyen Thai Binh Street...only about 350m southwest of all the Girlie Bars on Bui Vien Street.

What is interesting is that it is STILL a lamp shop...albeit under another name. I was called "Dung Osram" ...said "Yung-Osram"..which is the name of the woman that ran it followed by "Osram". Note the really tatty old awning below the main modern name...well I went there before that was new...on the 5th of November 2001...17.3 years later it is still a lighting shop.

If any of you EVER go to Saigon, this is the area to find lamps.....if there are any left!

Translation of the above text..."Google Maps has positioned me in Vietnam..."

Yes, that is what I said in the post above....read it again ....SLOWLY and CAREFULLY! Use a number of different translators if it makes no sense.

是的,这就是我在上面的帖子中所说的.....再读一遍....更慢,更小心! 如果没有意义,请使用许多不同的翻译器。

Translate it to Mandarin and back again a few times to see if the translation is consistent...

将它翻译成普通话并再次翻译成英文,这样做几次,看看翻译是否一致......
