Re: Coughtrie Lamps Question.
I remember those at the Minack Theatre!
They were all replaced during the mid nineties having done sterling service for many years in a tough environment.
I’m pretty sure that there was a 2 - 3mm evacuation hole drilled into the alloy near the threaded cable entry, and from memory there was evidence of water ingress but it has drained away so not causing any problems. I guess these were not designed to be mounted in this way, but they did last for many years.
I think you will be safe doing something similar.
Cheers.
