Thorn/Atlas Alpha 3 Lantern Installations
The Thorn/Atlas Alpha 3 was a common lantern throughout the UK. Mercury-vapour and low-pressure sodium versions were available. Their large size and aluminium alloy reflector made for an excellent light-distribution, utilized by an acrylic bowl. The lantern was side-entry only.

These installations of Thorn Alpha 3s are privately owned. This was the first time I've seen the Alpha 3 in person! There are 4 in total (all wall-mounted) but just next to them are LED floods, so I doubt these are still in service. Still, it is good to see some Alpha 3s in the wild!
This one's bowl is muddied and cracked, but I'll bet these would still work if turned on! The gears are located within the lantern's shoe, though remote geared examples were available.
Below, you can see the LED flood's photocell. It appears to have been taken from one of the Alpha 3s, as the end one is missing it's cell.
Dordon, Warwickshire
Some disused Atlas Alpha 3s exist next to Zaazu in Dordon, on a short stretch of abandoned road. There are four in total, with the first being located in the car park area.
This is probably the one in the best condition, despite the fact that one of the clips has come loose.
Another angle showcases the unique side-profile of the Alpha 3. The short lantern shoe means that these were remote-geared, and likely ran mercury-vapour lamps originally.
A closer view reveals the Atlas logo on the shoe.
The next column to be found is located on the abandoned road itself. This is also the most-apparent of the remaining three columns, having not been encompassed in vegetation.
Due to this, the lantern has suffered at the hands of vandals. Most of the bowl has been smashed away, but this gives us a good view of the distinctive reflector. No lamp is present in this one, as is likely the case for the other three.
Another angle of the same lantern.
The next column along is hidden in some trees, but the Alpha 3 can just-about be seen poking through the leaves.
From here, it looks like it's in great condition!
I moved around to find the best view of the lantern. From beneath, the lantern's bowl appears to have accumulated some dirt over the decades.
The final column took some scouting, can you spot it?
How about now? While the column itself is invisible due to the foliage, the lantern is poking out of the leaves. A crack through the bowl is apparent on this one!
