50s Polish Incandescent fixture named OB, made by A-23 Mazurskie Zakłady Near Giżycko in Wilkasy.

It is on a not-named road at the start of Brzeźniak village in Wielkopolska area. It is a public road take that intact.

@Emersyn - That’s a possibility. I wonder if they accidentally made a bunch of non-Alto F32T8/TL741s one day in 2010 and just decided to sell them off cheaper because they were incorrect. Maybe they went to some type of a surplus store and were sold off there.

You’re probably right about foreign lamps—they may not have the same order code. There are also just few countries that use F32T8s in general, besides North and Central America.

That’s alright about the photo.

It's probably Netherlands or Germany, though I guess Germany not...

I know that Trafficvisions were likely French due to the old version which was made by Mazda in 1992, named Modula.


Though Philips Originally was found in the Netherlands

The SGS203 and SGS204 originated from the Netherlands i believe...

Thats interesting how they have different date codes though

Today I found some 36w and 40w lamps branded as "Ecolink" with green sleeves. It turns out, they are just rebranded philips lamps.
Firstly, on the sleeve it says "made by Signify (formerly philips lighting)".
Secondly, the tubes are very similar to philips tubes, down to the etch layout, endcaps, and date code.

Unfortunately not, I went through my photos and found nothing. Maybe there's a possible the school district wanted a discount so Philips sold off some old stock to them? Or just low quality stock? But I think its definitely from 2010 because the lights were relamped in 2021 with authentic Alto F32T8/TL-741s and GEs.

If it were foreign, I'm not sure if would have an order code. I'm not really familiar with foreign lamps but they don't usually have order codes on them. Plus essentially all new Philips lamps have dark solid etches.

Purplish xenon color, and than LPS orange color.

What color do regular HPS lamps start up with?

Mercury free HPS lamps can cycle, but rarely. Have much yellower color than standard HPS lamp.
High xenon pressure HPS lamps can cycle, but rarely. Runs up much faster than regular HPS lamp.
Unsaturated HPS lamps are the non-cycling HPS lamp. Runs up bluish mercury. have stable voltage over life.
Regular HPS lamps can cycle.
I think that European HPS lamps aren't compatible with CWA ballast for HPS lamps as well.
