ORZ-1 retrofitted with a HPS lamp

ORZ-1 retrofitted with a HPS lamp

Old fixture from the 60s which I saw long ago with a working MV lamp was retrofitted with a HPS lamp two years ago. This is how it looks after the retrofit.

This lamp looks like a regular HPS lamp that requires an ignitor, and not like a HPS retrofit lamp for MV lamps.

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.

That what I'm thinking too, probably ignitor was added though no other means of renovation were applied to this fixture despite the fact that some care would do good as years can be seen on it.

I've seen photos of 400W lamps with starters made also by other manufacturers though the fixture above was made for use with 250W MV. Maybe it is some unusual HPS but I would be suprised if the person that had done the retrofit had the knowledge and knew that such lamp exists and that it will work here. Many electricians often choose the simplest option, sometimes even too simple (like SBMV in a MV fixture with a working ballast). Then again in the scenario of installing the ignitor that person must had the knowledge that it was needed so it must have been someone with qualifications, not some random.

Never heard about tubular HPS retrofits for MV lamps. Only elliptical and BT.

The tubulars with starters I've seen weren't retrofit lamps sensu stricte but should work anyway even if little bit underdriven relative to MV of corresponding wattage. This however doesn't seem to be underdriven ( https://www.lighting-gallery.net/gallery/displayimage.php?album=2822&pos=2&pid=172357 ) so it strengthens the notion that this is a very normal HPS with external ignitor.

The "optics" on this luminaire are terrible. It's a wonder any light makes it down to the surface.

Life is like a roll of toilet paper...the closer you get to the end, the faster it goes!  LOL

That's what happens after more than 50 years when optics are made of steel and are exposed to air. Still ORZ-1 fixtures were atleast made from good quality steel (and given proper care can be succesfully renovated), some other models like ORZ-3kł or OUR400 had the tendency to significantly disintigrate after so many years. Sometimes the leftovers fall to the ground when the back part rusts.

The same design seems to have been popular worldwide: https://www.lighting-gallery.net/gallery/displayimage.php?album=lastup&cat=0&pos=0&pid=172637
