Thorn Alpha 5

A lovely condition example of an increasingly rare lantern. This lantern had been adapted to run a 135w SOX lamp during its lifetime, but thanks to fellow collector J.T. it was returned back to original condition running a 140w SLI/H Linear Sodium lamp. This type of lamp basically uses the envelope of a 3' fluorescent tube complete with bi-pin end caps.

Photocell is a 1970s Royce Thompson blanking cell.

 

Thanks to Steve R for saving this lantern from Easton-in-Gordano.
