I think, generally, top entry SOX lanterns ended their reign in the 70s for new installations, however Thorn's 'Beta 5' was still available in Top Entry until the late 80s, as was Philips' MI50. So I'd say 80s for casuals. Your examples look as if they are from the mid-late 70s to the early 80s when the GRP canopy version became a lot more popular within the Z9530 range. It possible that the council had a stock of top entry SOX lanterns available at the time, but they are probably over 30 years old now. I've seen on UKASTLE that Enfield has installed some WRTL 2601s top entry and running SOX for casuals until fairly recently as well, but this doesn't tend to be common across the spectrum.

Yes, I'd second the date of 1970s for those. The first one with aluminium column is a spitting image of installations around the Fenland area which were put in during the 1970's. Likewise with the concrete column, up in York we also had Z9539's with metal canopies on concrete columns - the columns were 1950/60's Stanton 7s but the lanterns were newer, and were newer because the older roads then got developed during the housing boom of the 1970s when more houses popped up at the far end of such roads, and so at the same time the lighting was upgraded to SOX

Randomly stumbled across a brick-tastic installation near Worcester Shrub Hill station. There are loads of them in the industrial park.

Yesterday I did a bit more lantern hunting, this is what I have found in York: http://goo.gl/maps/8uzTU

Yes, I'm keeping an eye on that one. I thought it'd get replaced with an LED bulkhead when the rest of the road got LED windsors, but it didn't. It doesn't work and is just a ledge for two feral pigeons currently. There's another one under the overhang of the theatre nearby.

The one on the theatre nearby has a connection box with the number 6 stuck to it, so this could indicate there were once more of these lanterns nearby.

It's probably that it was counted in with the lighting of the road itself... the column by the bus stop in Exhibition Square for the Reliance 30/40 buses is marked as number 7, whilst the column by the De Grey rooms is 11. When looking at the front of the theatre, there is a wall mount on the next building to the right, that is number 2, with number 1 being the next one along - so presumably this means the two Z8600s on the theatre frontage itself are 3 and 4. There could have been another top entry under the overhang or a column on the side of the crescent building which would have been 5, then the redundant Prefect is 6, 7 already mentioned, 8 would be the Albany near the CCTV camera on the corner of Gillygate, 9 and 10 would be the double column by the bit of historic wall and Bootham Tower.

Fantastic find Bob! I bet they haven't been maintained for a while, mind.

There are only a couple of HW932s that managed to slip the the Enfield PFI core investment period and can be seen here. They are both day burning due to the fact they're time switched (they escaped the photocell fitting scheme of the 1980s too!) and the lack of attention implies that this access road has been off the radar for some time. In fact the lack of signage and the ability to view it fully on GSV implies that this is now a private road; the fairly recent Beta 5 casual replacement - installed on a 6 m column, normally used for Arcs - must have been a request put in for the council to replace on the school's behalf.

It seems odd that a road would just suddenly go off the adopted map like that... makes me wonder who will be replacing the lamps when they fail.

Please note that due to GSV having now been around for quite some time, we are deciding to wind down this thread over the next few days. Any GSV finds can still be posted about, but we are now devolving it into the various regional threads... for example, a GSV find for York can now go into the Yorkshire regional thread; a find at a London Overground station can go into the London and SE regional thread or in to the railway station lighting thread....

This thread will remain extant for a while during a transition period, but will eventually be archived. For further information, please contact Alex or put a post into the 'announcements and enquiries' section.
