I'm looking for a mounting for garden floodlights, so that I can adjust the height and angle according to the season etc.
I'm thinking of two tubes a couple of feet long, one of which can slide and rotate within the other. At the end of the outer tube is a hand-wheel to lock the inner tube in the desired position. Think of a microphone stand and you've got the right idea, roughly, except that mine would be bolted to a low wall.
This a widely-used type of mounting but does it have a name and where might I buy some, suitable for outdoor use? I'm thinking of possibly a chandlery, but I don't know what to ask for.
I'm ready for a bit of bodging if necessary.
