Underpass lighting

Underpass lighting

Click to view full size image

Every two years we replace about 70 circling lamps in one of our underpasses. The fixtures are hexagonal shaped and accommodate two circling lamps, one 32w and one 40w. The cover is made of heavy walled PMMA plastic hence it is vandal proof.
Since a couple of years we only replace the 40W tubes and disconnect the 32w lamps for saving energy. they run 24h/365days since 1976 and all of them have still their original ballasts. The biggest problem in these lights are the very brittle lamp sockets and the new Chinese Circling lamps with their inward bended pins. I think we redo the entire lighting in the underpass in the next 3 years.

Interesting fixture. It reminds me of those chemistry molecule diagrams. Also, cool that it's circline. I hope you can save one when you upgrade them.

Collect vintage incandescent and fluorescent fixtures. Also like HID lighting and streetlights.

Ciao!
Belle lampade; perché non cambi i soli portalampade? se metti luci attuali finirà che ogni due anni dovrai cambiare tutto l'apparecchio e non solo le lampadine...
Tu sei svizzero italiano, francese o tedesco?

Hello!
Beautiful lamps; why don't you just change the lamp holders? if you put current lights on you will end up changing the whole appliance every two years and not just the bulbs ...
Are you Swiss Italian, French or German?

Hi SPQR

I think that the Circling lamps are going to be discontinued soon and the lamp cover are very expensive to reproduce if they break.

I'm Polish but live in Switzerland

Convert them all to PL-L 2x18W, using the existing 40W ballast and two starter holders. Just install new sockets on the spine with self tapping screws and rewire

(I would also stick adhesive Aluminum foil as reflectors behind the tubes, to improve the light output)

Yeah but the cover is still a problem. I have no spare and they are very costly to make.

Haven't broken in 42 years, why would this become a problem now ?

Save all the good fixtures with good covers, and any bad fixtures with good covers, keep for spare parts. These are cool and would look nice all cleaned up and restored.

Because there are always such stupid blokes which are destroying everything thus if they destroy the covers with such a force the fixture is no longer usable.

As for replacement covers making : Polygonal shape gotta be fairly easy to make as there is no bending required. Order a single big sheet cut on laser to a tile set for multiple covers, and glue it yourself with PMMA adhesive in a template holder (build it with plywood boards around a sample good cover)

I can remember these fixtures! In holland we had on some locations same ones. Gone for many years now. So, in these years quality was made! Will be transferred to LED of course...

This underpass was constructed in the sci-fi era of the 1970s. Like everything of that time till the mid 80s had to be designed with octogonal or hexagonal shape like those space ships and buildings in many popular cinema movies of that time.

We are facing the problem in that underpass that the ceiling has adapted spacings for these lights so the new fixtures need to have somehow the same shape to fit into the ceiling. Let’s see...

Will you preserve some of these when you'll replace them?

Beautiful fixtures anyway. Are them Swiss made?

Yes I gonna save some.

They were made in Basel by Gysin AG. I think the factory closed down some time ago because the owner retired and the company transformed to a trading company which is now known as ” Wieland Trade GmbH”.

So there's some good old swissness going on there. That's a shame that probably the new fixtures that'll replace these beautiful ones will be crappy China LED products like is happening in the rest of our country. I found that Lugano is quite an exception in this regard, as a lot of the good old Siemens Kleine/Grosse Klassiker that used to be everywhere here are being replaced with new Siteco HPS fixtures instead of some LED crap, which for sure is better. But in the rest of Ticino and Switzerland LEDs are now the main way to go when replacing old streetlights.

Don’t worry mima. We do not buy Chinese fixtures!
Modern LED streetlights are made by Philips Poland and Philips (Indal) Spain. Post- top streetlights are made in Switzerland (Huber) and Germany (Zumtobel - Hess). Modern linear LED underpass fixtures are from Italy (Designplan). For the old town the lights are from Germany (CIGS) and some were made in-house by one of our metalworker.

I thought Lugano changed to Schréder didn’t they? Ten years ago I had to make light calculations for their larger roads around the lake with Schréder Furyo range streetlighs but I don’t know if they finally did choose them?

The fact is that I don't like LED fixtures at all, I much prefere the classic HID stuff. Often the LED fixtures put out a very sharp, glaring and annoying ice-cold light, not confortable at all for night vision. Not to mention that, given the fact that they consume less energy, usually municipalities increment the number of the light posts, increasing light pollution to a big extent and in fact nullifying the energy savings. What the utilities are doing here to me seems really stupid.

And, being an HID enthusiast, I just find LEDs plain boring but this it's just me.

Especially for HID they're mainly focused on Siteco products. In particular these are the HPS fixtures now you find quite everywhere here in place of the old Siemens Klassiker:

https://images-na.ssl-images-amazon.com/images/I/41eK9Y5QABL._SX425_.jpg

But there are also some of these Schréder Furyo already in service, especially around the new Lugano's cultural center (LAC, probably the road for which you did the calculation is the one which passes in front of it). But apart the section near the LAC, the Lugano's long lake for now for most of its length still have the old Siemens Grosse Klassiker lanterns, the pendant version. But I bet that sooner or later (more sooner than later) they'll be replaced, they're there for a good 30 years now.

I hope that at some point I'll manage to put my hands on a couple of these Grosse Klassiker, both the post top and pendant version, before they'll be totally disappeared. I already have 3x of the Kleine Klassiker in my collection.

But LED is reality if you like it or not. I also like the HID and even more the fluorescent and incandescent “world” but we have the LED now and and there is no way to escape.

Some of our roads in the city are lit by warmwhite LEDs and we rather choose lanterns which are having more LED dies with lower wattage installed in a fixture so we can omit glare as much as possible compared to streetlights with less number but much brighter LEDs.

So yes it’s possible that they probably carried out the project I did take care party back then when working for Schréder. Some day I have to visit Lugano and see how they are looking like now.

Good luck to get more of the Klassiker luminaries!

Maybe some adapter plates can be made instead of old fixtures?? Yep,old lamps were good, now we have LED, good or or not... Some companies will see that the LED lamp posts installed in the beginning now will fade slowly and/or broken ballasts. Nothing can be replaced, so new fixture again. And this is more expensive than changing the lamp itself!! ( Fixture, labour and short lifetime)

Almost one year has passed since I replaced all the circlines and sad to say that one third of them barely gives some light and the other ones do start to flicker in cold weather.
Consequently we will replace them all again... one year earlier than supposed!
Since Signify is not able anymore to deliver quality circline lamps we now tend to put LED substitutes preferably warm white lamps.

Yes exactly we are looking for LED circlines which work on these chokes. Our town is celebrating some jubilee of 2000 years existents so we have to clean the bowls anyway and remove any dirt of them.

Most LED lamps that are lower power than the FL's they replace (like 18W LED for replacing 36W T8 ) don't care about the choke, they work the same with straight 230V or choke in series. Some of the higher power lamps do care and either require the choke or 230V without choke

Or you can place some enclosed module inside that connects to the 230V terminals, and leave the FL gear disconnected
