At start, once again the Philips destorts the red that the camera sees, the SLI has this soft pink colour, but what I can`t show you here, is the discharge of the SLI `bouncing` in and out of the cross section of its tube.
Other Linear owners will know what I mean by this.

Hey I see you have Neon, Argon and Xenon penning mixture for the linear version similar shown at James Hooker's site: Atlas SLI/H Linear Low Pressure Sodium

Nice

Pretty, please no more Chinese failure.

I don't know why the current SOX type LPS lamps haven't this penning mixture (The argon, neon and xenon).
This penning mixture have higher efficiency for the LPS lamp then the regular 95% neon and 5% argon penning mixture.
This is probably simply that because SOX type LPS lamps are less common today, they are much more expensive even the much more complicated HPS lamp, so manufacturers don't want to continue to improve the SOX lamps by adding a xenon to the penning mixture as Thorn did in their SLI lamps, which would rise their cost even more.
This is a common problem with digital cameras to destorts the red color of the neon and translate it to the original orange color of the sodium (The neon btw, have a spectral line that lies almost in the same wavelength as the sodium D double spectral line. If you would even look at a neon negative glow lamp through a cyan filter of a stereoscopic 3D viewing lenses, you will see the lamp glowing an orange color not different then the LPS lamp), thing that also makes the filming of the running up of SOX lamps even harder when the camera moves sometime.

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.

Just looking at the pics of your LPS lamps running up and lit LinearSLI/H. They are beautiful lamps arnt they. It still seems strange to me and hard to accept that Linear LPS have become so rare and sought after now and so few of them about . I can clearly remember a time (and it doesnt seem that long ago) when they were everywhere here in Derby and Derbyshire. I have many special memories of them . Particularly dark misty winter / December nights in the mid 80s when I was catching the bus home late from school in Etwall in Derbyshire (after rehearsals for the Christmas plays where I did the lighting) . Also memories of an "old" girlfriend from back then who used to see me off at that bus stop xxx !. Next to the old stone bus stop (which is still there) was an old 8m concrete column (also still there , but sleeved now and with an ARC 150 w HPS lantern) . This had a 140 watt linear lamp in a Thorn Alpha 5 (the whole road had these). I clearly remember looking up at that old lamp and lantern , it was like an old friend. VERY special memories.
As I say it is strange to think how these lamps are now rare collectors items , when they used to be so common round here . And , to me anyway , it doesnt seem that long ago at all !!

Ah yes, do you remember that `linear bounce`, where the discharge would jump in and out of the sections of the tube as it warmed , this was my early memorys of them as a kid.
Before I knew what they looked like close up, or how they worked, as an 8 year old, I use to think there was a giant filement in them, that shook about as the column shook in the wind!!!!!

I still find this `bounce` fascinating watching mine running now , I also have fond memorys of the golden linears in the GEC 9517 Clearmain lanterns that were all over Middlewich in the 80s

You lucky buggers. Foggy evenings in Darbyshire with a street lit by SLI-H's, did I dream it or was it actually true!
I'm not a real luminare man, so feel free to correct me if I'm wrong, but is was a couple of SOI-H 140s in Thorn Alpha 9s (I think) which got me hooked onto lamp collecting when I was four years old.

In my neighbouring town there were a lot of the old, top entry `open refractor plate`, GEC Z9425s using the 140watt SO/I during the 50s/60s/and 70s.
There were 2 on the railway bridge next to the bacon factory that remained in service, (on their original concrete columns), right up to 1983!

I agree they are Lovely Lamps, It's such a shame they've become rare!. I have never seen any in use so they must of all been just about completely gone by the time I started Collecting in 1997

Its the monochromatic light which "grabs" you, it is so penetrating, so intense. As a little kid, I called LPS luminares "Orange Longeys", because thy were orange and they were long! I could not understand why they did not look orange during they day though!

I used to think the street light out the front of my Old house had a Yellow Fluorescent tube in it. I remember seeing the capacitor from the floor inside the lantern, I used to think that it was the starter lol. when I held a SOX lamp for the first time in about 2002 I was facinated by it! it was a heavily used one and it was strongly banded.

In 1975 there was a SOI-H 140 in a display at the Museum. I used to go and stare at it for hours. Eventually it disappeared. It re-surfaced 20 years later at the Alanvale college in Lanuceston, 180Km away and it was damaged. To this day I have not managed to acquire it.

I got my first SOX lamp when I was 12, it was a GEC, (from the contractors yard in my albums), and like Dan I was facinated by them.
At this time I knew nothing of the SLI/H linears though, it was only when we went to my grandmothers one Saturday morning I got a first look at one.

Cheshire Highways were out re-lamping the SLIs on Chester road in my town, and our car was in a que to get past their 12 metre bucket truck that had to be parked on our side of the road.

As I looked up at the guy opening the bowl, (it was a bright sunny morning, so I had a good clear view), I saw this tube with a `zig-zag` inner tube!!! my thoughts were "what the hell is that, thats not a SOX"???

It wasn`t until I was 15, and doing a project at school on lighting, I met street lighting engineer Steve, (now a good friend of mine), who showed me a linear, when I described to him what I had seen that Saturday morning, that he had in the back of his bucket truck.

He didn`t have an old one on the truck, but woud have given me one if he had, but he gave me a 1978 Thorn lighting catalogue that had all the SLIs information in, and this was the first time I knew of the sizes and wattages of these lamps.
