An old Thorn Gamma 6 deep base variant that used to be in my street prior to 1990 when they were replaced by Thorn Beta 2s. See photo on the right. 55w SOX. 2 photos showing that different photocells were used during it's lifetime - firstly a thermal Royce Thompson P5, then a Zodion. Some streets in the area are still lit by one or two of these and they must easily be 40 years old - including the columns! How much longer they will last is anyones guess, but LED lanterns are replacing them so their days are numbered - and I hope to add a Gamma 6 lantern to my collection some day!!

The Thorn Beta 2 that replaced the Gamma in my street in 1990. 55w SOX with Zodion photocell.
From July 31st 2010 our street had Urbis ZXU1 lanterns - and since October 2023 we now have Schreder Axia 3 LED lanterns - *SEE FURTHER DOWN*.
Below is another Beta 2 in the area and its bowl has gone walkabout.

A Thorn Beta 5 from the 1990s. 35w SOX with Zodion photocell and a little bit of water in the bowl.

A GEC Z5698U lantern - a few of them can be found dotted around the area. 55w SOX with a Zodion photocell - possibly SS2.

 
A couple more Gamma 6 type llanterns. At one time most of Horfield was lit by these and as of 2023 a small number do remain but LEDs will replace them. Some had faded black paint over the years like the one above right (which was the only remaining one of its type in this particular road - Mar 2004 - now replaced).

And in one or two rare places of the area can be found a Gamma 6 variant complete with a nifty little hat to direct more light down on to road. This one appears to have a SELC photocell.

Here we have a couple of Urbis ZX1s - the bottom one was less than 5 years old but they still replaced it with a new one when there are far more ancient lanterns nearby yet to be replaced! Looks like the photocells are Zodion on the bottom one and SELC on the top one.

Two Urbis ZX2s one with full cut-off and one with deep bowl. SON-T 150w bulbs - possibly both with SELC photocells.

An Urbis ZX1 - these were the lantern of choice for replacing the old SOX lamps in the Horfield area. SOX light is fast disappearing in the district. A Zodion photocell controls it.

31/07/2010 - An Urbis ZXU1 lantern replaced the 20 year old Thorn Beta 2 in my street. The case design is slightly different to ZX1 as it has a universal fitting i.e side entry or post-top. Until mid June 2013 these lanterns had SON-T lamps inside but were replaced with SDW-T white SON lamps. This was more pleasant at night.

An Urbis ZX3 on a main road. At the time of the photo (Mar 2004) this was the only one with the rest being Philips SOX (see below) - all have since been upgraded to SON-T.

A PHILIPS MA60 180w SOX streetlamp. A SELC 841 photocell is on top. If you imagine that the photocell fits nicely in the palm of your hand you can imagine just how long this lantern is!! And to prove it here is an interesting photo!
