REVO Caerlleon Lantern Installations
Also sold as the REVO C6074, this lantern was designed for 1500W GLS lamps. The Caerlleon could be offered in top-entry or post-top forms, with the design slightly differing between the two. It was also sold as the "Municipality" with a cast-iron stand to fit bridges, memorials, public squares, and similar spaces. With this stand, the installation was 10ft (or just over 3 metres) in height.
Chester
The first time I encountered the Caerlleon was outside of Chester Town Hall. Two ornate cast-iron pillars support post-top C6074 lanterns, with this set up being the aforementioned "Municipality" lights.
The lanterns appear to have replacement panels nowadays - the yellow tinge implies a polycarbonate composition.
I positioned the sun behind the lantern in an attempt to see what exactly the lanterns internal construction was like, but my question was answered twice later on. First, I found this image online of the lanterns running orange lamps, what may be SON.
This is the second lantern on the staircase:
The spigot for mounting is separate from the lantern itself.
Another Caerlleon was spotted much later in the day as a surprise-find on my way back to the train station, along Upper Northgate Street. Unlike the previous two, this one appears disused, and the panels have suffered some damage.
The panel is still in there, and these appear to be glass originals. The post-top spigot is also removed and the lantern fixes directly to the signpost.
There is no lamp in the lantern, and the lamp-holder appears to be wonky.
Chester is perhaps the nicest city I've visited, so it wasn't hard to find an angle that made the lantern fit in to the scenery.
