Overkill is quite an understatement when it comes to such a lantern arrangement! I wonder why lamp manufacturers in Eastern Europe never developed a proper 1 kW HPS lamp.

Probably technological limitations with specific combination of unique economical system and central steering of resource distribution by the goverment. For example in Warsaw there were light towers with twelve 1kW MV fixtures but as 1kW MV fixtures were a "rare" resource officials in Bydgoszcz city didn't have the possibility to request distribution of such fixtures to them. Therefore in different part (but relatively close) of city than the one where 12x400W towers were later located, there were installed towers with 20 MV fixtures, each one for two 250W MV lamps which resulted in 40 lamps per tower. In many polish cities the use of light towers instead of bigger number of single fixture lampposts was some sort of pride, showing the greatness of each city. Each region of Poland had distinctive style of light towers, for example in Tricity the most popular configuration was the 10 MV fixture configuration, most often with 2x250W fixtures but of course there were some exeptions with different fixtures and the number of fixtures.

Thanks for detailed and very interesting description. I am really amazed that these multi-head light masts were a source of local pride in the East. Here in the West this would have been a clear sign of inefficiency, something remedied with better lighting systems made with fewer luminaires. 40 lamps per mast... I still can't wrap my mind around that... This would really be inconceivable here.

Here, we uses light towers with 8-12 1000W HPS lanterns, either local made (General Engineers or Steinitz), GE or Holophane: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-108511

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.

An example of such tower with 20 fixtures can be seen here:

Years later the number of the arms was reduced to 10 and after many changes in fixtures last time I was in the are there were installed Philips SGS204 fixtures.
