HID, LPS, and preheat fluorescents forever!!!!!!
|
| Whenever I look at videos of Eastern European street lanterns, I seem to notice that there are many examples that use 2 lamps rather than one. I wonder why a number of Eastern European countries seem to embrace 2 lamp street lights unlike the US?

| If u want get Technical here we have lantern but u find mostly
Those in parking lots those Stacked cubes then we Have 16
Lamp fuxture called Acre of light containing 4x BT 56 lamps per side. Here most of it had to due with our autotransfomer ballast. It just eaiser to wind it for high wattage lantern as such as Westy OV35, OV50, GE M1000, and the AEL 327 sufice lighting large interchange here. Two lamp mercury ballast is made but made for two remote ballasted street lights, such as two ov 20s on the pole.

This reply does not answer the main question on this thread. The original question is to explain why parts of Eastern Europe adopted 2 bulb street lanterns such as this one where a single lantern uses 2 bulbs in it: https://youtu.be/gWpVLT5JHlU |

| I believe the two lamp fixtures were intended as a way to dim them late at night by switching off one lamp.

| I can think of a few reasons.
One is to allow for operation during the overnight hours (12am - 6am) with only one lamp to save energy and lower light levels when the streets are less busy. This concept was also used in some parts of North America. The triple 700w MV (later 400w MH) Hollywood special luminaires only kept one lamp lit during the overnight hours. Other places used poles with arms that allowed up to 3 cobraheads to be mounted in the same direction instead of multi lamp luminaires.
The other is to allow a common lamp wattage. For example residential streets can be lit with a single 125w MV lamp per luminaire while commercial districts can be lit with two 125w MV lamps instead of having to stock the lamp and gear for 250w MV.
Finally it allows the mixing of light sources in the same luminaire. I believe some places had luminaries that were designed to burn MV and SOX.

I also noticed that in Russia, Poland and other countries they use two fixtures in a single pole.  |

Do you mean 2 bulbs per fixture? In many countries, there are many street lighting columns that use 2 lanterns per pole. |

Long live the HPS and SOX!

| I don’t know a lot about European lighting, so I can’t say that my answer is perfectly correct. I would guess that fixtures either have two lamps to: 1, make them twice as bright, or 2, allow half of the fixture to be controlled independently to conserve electricity.

I’ve always been interested in all kinds of lighting, mainly incandescent and HID, and especially all kinds of sodium lamps (HPS/LPS). I’ll tolerate LED but I’m not a fan of it.
I’m not proud to say that my city has Devolved to LED.

| Why only in eastern Europe?
In Switzerland many roads were lit by two lamp streetlights back in the days. Most of them were MV+SOX format but also fixtures with two MV and bit rare MV+HPS or two HPS lamps in one fixture.
Western Germany also had such installations and there are/were some known in France.
