I've been through that part of Swansea and it was very nice to see so many Z9564s, although, as you say, some of them are in poor condition and I'm not at all surprised that the capped columns have been replaced, as the maintenance of lighting seems pretty lack down there.
Here are some more photos of Aberystwyth!
Quebec Road still boasts a fine offering of Eleco GR150s with there being EIGHT in this photo (not including an SRS201 replacement at the end of the road). Sadly, this will probably be lost soon to the Luma domination, which seeks to replace columns installed in the early 70s. Many of the lanterns on this road did burn red or were out, however many have been relamped recently, but still face being removed.
Aging 1970s Eleco GR150. This one is set further away from the road for some reason.
2000s Philips SRS201 (150W SOX)
Now for a rare sight, a lantern from the 1970s retrofitted onto a much newer column (late 90s?) I'm surprised the lantern wasn't just replaced when the new column was installed. It is not clear if this will survive the LED lantern replacement works.
1990s WRTL MRL6 (250/400W SON) This must've been one of the first SON lanterns in the town, and was the only one after its neighbour got replaced a couple of years ago. This has now been replaced.
1970s Eleco GR150s, 135W SOX. The lantern in the foreground is being replaced as I type this. Note different bracket lengths.
GEC Z9554 (135W SOX). Examples exist in the town but replacement schemes have taken their toll in the past years - There are no deep bowled examples remaining now. This however, has escaped the replacement works on Llanbadarn Road, most probably as it is not as old as the GR150 installations. SOX and LED lighting contrast at night really is something!
The new order of the day in Aberystwyth! WRTL Luma running LEDs.
Close up.
An Urbis ZX3 (150W SON) awaiting replacement next to a new LED lantern (if anyone can help with identification here). Both are currently lit!
1980s Philips MA50s, gear in shoe.
Close up. Notice long bracket and seagull!
1990s Philips MA60, 180W SOX. A section of these have already been replaced by WRTL Lumas.
This one, however is fitted with a node.
Urbis K-Lux running an induction lamp.
Eleco GR151, 135W SOX. A very rare lantern and now sadly the last lantern remaining in the town. Two more did exist a couple of years ago by a level crossing, but were replaced by Urbis Sapphire 3s, which, themselves have now been replaced by Lumas.
Close up, this is not due for replacement however some columns on this road are becoming heavily corroded and are being cut and capped. This lantern has not long just received a new lamp.
Eleco GR150 on Fabrikat column, in surprisingly good condition.
Three generations of lantern in one photo! Foreground: Eleco GR150 with Philips SRS201 (135W) in the background, and then twin Iridiums. Both of the SOX lanterns were unlit until recently, although wiring for new columns has been completed and therefore replacement is imminent.
Eleco GR150, a close up of an example with a clouded bowl!
