LED Relamping

LED Relamping

Click to view full size image

This nice and old Norvegian street light got already its fourth type of lamp in its long life. It originally held a MV 80W and occasionally plug-in HPS 68W lamps before it got its 80W lamp back. Then in 2016 I shunted the ballast and put a 30W CFL and now after the CFL died the LED 21W took its place. Surprisingly the light is very pleasant under this lamp.

Looks good! With a longer lamp would probably look even better - unfortunately they're rather decorative low wattage lamps, not suitable for this purpose.

Not very happy with the current mess on this site.

A filament LED would probably be better suited optically. They do make 100W equivalents now.

Why not to put 70W internal ignitor HPS lamp? It works OK on the 80W mercury ballast even if it slightly underdriven.

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.

We did make trials with these SON/I lamps years ago and they worked not stable and failed quickly on MV ballasts. Only the 110W and above got better results though.

The LED solution is temporary as this fixture is going to be replaced this year. It passed 40 years of service which is fairly enough.

Really? I thought that these little SONs with embedded ignitor were meant as a retrofit for MV lamps. Actually one of these was in the SiStellar City (https://www.lighting-gallery.net/gallery/displayimage.php?pos=-176254) I rescued together with the Grosse Klassiker. In that place there were also a bunch of Kleine Klassiker, which I didn't rescued because I already have 3 of them and were all in a pitiful state, however I took a couple of ballast trays from them just to have some spares. And also in some of them there were these SON/I 70W lamps, which I took with me too.

Seeing these lamps with embedded ignitor used in fixtures intended for MV bulbs, made me think that they were meant as a retrofit.

Is there a specific utility company job for repairing street lights?

Long live Mercury Vapor and Incandescent street lighting!

Only the 110W and and above are retrofit lamps for MV ballasts. The lower wattage 50W and 70W with starter inside are meant for HPS ballasts only! It was in the late nineties that salesmen here in Switzerland from both, Philips and Osram were recommending to use the smaller wattages on MV ballasts but it went terribly wrong. I remember that they were saying that one could use a SON 70W/I on 70W ballasts and the 50W on 80W ballasts. Some time after wast numbers of complainants they withdrawn their recommendations.

OK, that's interesting to know, actually it sounded me quite strange that a retrofit lamp would have the same wattage of a standard SON lamp. Usually retrofit HPS lamps have different ratings.

Just a side question now, because I'm curious. If these lamps aren't meant for MV retrofit, why the manufacturer put in them a glowbottle starter? Maybe to enable other manufacturers to build HPS fixtures at lower cost as an external ignitor is no longer needed?

You could get an LED filament lamp for this. I'm not sure if you have it in your country but I have heard Diall is a good brand in europe.

Any machine is a smoke machine if you operate it wrong enough.

When HPS technology was becoming mainstream in the 70's the need for a ignitor was seen as a problem for fixture manufacturers. The lamp manufacturers created self starting HPS lamps to simplify fixtures - making them easier to design and lower in cost.

Yes especially for smaller wattages. It was a challenge to integrate a huge ignitor in a small fixture and thats why the first small HPS lamps came with integrated starters.

Not here in Switzerland. In cities and large municipalities the resident utility companies with their line men crews are doing the street lighting maintenance. In smaller municipalities sometimes electricians are doing this job but they do not have the same knowledge about street lighting like a lineman do.

But the bulbs I got, which are Radium RNP/E-I 70W (they're marked as Radium but in fact made by Osram) are of recent manufacture. They're made in Slovakia like their Osram counterparts (https://www.lighting-gallery.net/gallery/displayimage.php?album=2797&pos=70&pid=123877), they look exactely the same and even the etch's style is the same. I have one of the bulbs right in front of me, there's a "T 5 18" code printed on it, I suppose is a date code.

Yes there are still many HPS fixtures in the world without ignitor.

OK, I didn't know that thing about ignitor-less HPS fixtures being still in service since the beginning of the HPS market. I thought that this would be quite a new thing.

Yep. Even we have couple of old early 80s street lights still in service with SON 70W ballast but no ignitor. We could now add ignitors to it because they are small now but the back then when the first low wattage ignitor were introduced they were as big as a ignitor for 400W lamps. At least the BAG Turgi ones.

I remember that when I was a kid a neigbour donated to me a 250W linear metal halide floor lamp of Swiss fabrication (I don't remember the maker), of the type that you usually would see in an office during the 80ies. It had the power switch, the ignitor and of course the bulb in the head and in the base it had two bulky Leuen Berger ballasts wired in parallel if I remember correctly, and a quite big cylindrical BAG Turgi ignitor, I think of the same type you're talking about. Unfortunately it got lost in the years, probably it was thrown away.

This fixture was offered by Alumag Belmag AG from the late 1960s till early 80s. It was made by a Norwegian manufacturer called IFA. Since it was an imported product it was fairly cheap compared to the more complex and bulky own branded fixtures.

I remember these indirect lighting fixtures with HQI-TS lamps. The one you are describing is most likely made by Regent Lighting AG from Basel?

I was meaning the HPS ones without ignitor . Or maybe the one in your photo is one of them?

Yes, now that I remember probably my floor lamp was made by Regent. It was of very simple design, two "shoe boxes" (base and head) held together with a long, metallic rectangular rod. The whole fixture was painted of a creamy-white colour.

As late as around 2015 residential grade HPS fixtures without ignitors where sold in Sweden.
The most common and easiest HID bulb to buy in Sweden without going through a electrical contractor is the internal starter 70W HPS bulb.

Many of these fixtures where earlier offered with mercury gear but as mercury fell out of favor they simply changed the ballast for a 70W HPS one. They could keep the optics and general design but offer a more energy efficient fixture.
