Thorn Alpha 2000 Lantern Installations

The Thorn Alpha 2000 was most-common in France, but examples did spill-over to the UK. They were very heavy due to their aluminium composition, designed for 250W and 400W SON lamps. Post-top and side-entry mounting options were available, along with a choice of flat-glass, curved-tempered glass, or deep-glass bowls.

These examples line the Derby Southern Bypass, running 250W SON respectively.

Another example (column BL151) along the Derby Southern Bypass. The ones here are all on single-arm 12m columns. The 250W SON lamp is just-about visible through the bowl.
