Wow Does it connect to Delta or Y phase line?

Pretty, please no more Chinese failure.

Sorry, I don't know. These types of lamps (both 3 and 6 kW version) have very special ballast, with universal input voltage (220V/380V).

Robert, if I remember correctly this lamp is meant to be run from three phases via a delta connection. The two electrodes at each extremity of the burner share one phase and that's why they are smaller and draw less current (4.3 A) than the two middle electrodes (7.5 A).

Max, I have a question -- whether exist analogues (or prototypes?) of these lamps developed in Europe or U.S.?

Thanks, Max. SilverRay just recently post a circuit diagram for such this lamp.

Pretty, please no more Chinese failure.

As Max already said the order of electrode connections in circuit is very important for these lamps.

SilverRay - I am not aware of similar 3-phase HID lamps being developed in Europe or North America. However, I know that in 1990 Johan van Vliet of Philips designed a 3 kW HPS lamp for three phase operation, but it consisted of three 1 kW HPS burners connected in a Y configuration inside an helium-nitrogen-filed bulb. Much later Sylvania made a 1800 W 3-phase HPS lamp also with three burners, but they were connected in a delta configuration. The only discharge lamp with a real 3-phase burner that I know of is a special Tesla RV lamp from Stanislav Slabyhoudek, this is a prototype that was made in Czechoslovakia during the 70s if I recall correctly.

are the two central electrodes connected to the ignitor?

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).

I lives in Israel, which is a 230-240V, 50hz country.

Very cool!

Good quality things are awesome. Cheaply made things are not.

This plant in Moscow (Russia) produced 3 modifications of such lamps - there were no analogues in the world! 1) DM4-3000 as here on a photo, and also: 2) DM4-6000 http://ixbt.photo/?id=photo:1230121 and 3) DM3-3000 http://ixbt.photo/?id=photo:1093247
