Re: Coughtrie light
I have a light similar to the pictures. The scew-in glass cover would not unscew to change the bulb so I smashed it. All that is needed is a tube to shield the bulb, it does not need a base to catch spiders and thrips.
To enable scews to be free to undo in the future I use Waxoyl which is sold for undersealing vehicles. It is based on white spirit and is a thin penetrating liquid if warm. It then sets to a soft wax.
