The big 200W GEC SLI/H is sown above the small 10W GEC SOX. The SOX is the same diameter and has an old fluorescent cap.

Great image! Now that I see these two lamps side by side for the first time, I wonder if both had the same outer bulbs, just different lengths. GEC was unusual in that whereas its Linear lamps had a constant thickness of the IR coating along the length of the lamp, the single ended SOX had a graded coating thickness, so as to keep the relatively cold U-bend as hot as possible relative to the electrodes end. Since the 10W lamp is so short, maybe they could get away with a constant IR coating thickness along the tube like on SLI and use the same coated tubes. It would be interesting to check the colours of the reflections in the SLI and 10W SOX to see if there is any similarity.

That is interesting, Mark. Using the existing linear fluorescent glass materials to create these wonderful SLI and low power SOX bulbs

Pretty, please no more Chinese failure.

Thanks.
I had a go at comparing the SLI lamps with the 10W SOX, but I can’t say the coating looks identical. The SOX has a green/yellow hue that doesn't appear the same on the SLI lamps. The diameters of the two lamps check out almost identical. So I guess the glass could originate from the same line. Like all SOX the coating on the 10W doesn't continue to the rounded end of the lamp so it wasn't a cut section from preformed SLI/H.

I did also spend a bit of time looking at a GEC 35W SOX from the late 70s and can’t say I can pick out any graduation on the coating over the length of the tube. Perhaps I could spot it with a thermal camera but I am not sure that would be easy to identify in such an experiment. James, did GEC introduce this early on?

Ooh, a baby SOX lamp, with his daddy.

LED lighting has its place in the home or other indoor uses, but outdoors in street lights is in my opinion not one of them.

One day I will get both of these... Well probably not these actual ones, but you know what I mean

I don't disapprove of LED's for domestic and other indoor use, I just don't like them for street lighting.

It will probably be sometime in June or July, depending on finances, we'll let you know.

You guys are "such lucky buggers" to still have these around....getting them here in one piece would be a risky process.

Hey, I've never even seen either of these in the flesh, let alone come close to actually having one

Compare the area of Australia to the area of the U.K. .....What about the populations, c25mil here. what is it there, 65mil or so?

Lets say there is one SOX-10 for every 50,000 people, so that's c440 here and 1300 there. What about their density?

Area of the U.K. is a quarter of a million square kilometeres...that's roughly one lamp per 200 square kilometeres.

Area of Australia, 7.7 millon square klometeres...so one lamp every 17500 square kilometeres...or about 1/100th the density.

Now, admittedly the lamps and people are not sprinkled over the area like salt on a plate of food, but you get my drift.

The chances of there being ANY SOX-10's in Tasmania is minuscule and I would say that it is actually zero. There are many lamps in my collection that are the only examples on the Island and quite a few that would be the only examples on the continent bar a few other collectors' collections on the mainland.



Guaranteed there will be some of these closer to you than me!
