Rise and fall lamp pulley set
The pictures attached show the system which I found today- hiding in a box in a corner of the garage underneath my hank of green/yellow sleeving for wiring jobs (I needed a bit of that for another little job I was doing).
It's quite neat with no sticky out pulleys, just the two units, one for fixing to the ceiling and the other weighted unit to thread the wires through. I've threaded them up with some single core flex just to show it in operation- the wire from the upper unit tied onto the hook is the power feed in at the top and the wire hanging down from the lower unit would go to the bulbholder rather than the mug in the picture! To raise the lamp, you grab the bottom unit and pull it down, to lower it grab the lamp itself and pull that down. The lower unit is weighted noticeably and that together with the general mechanical "inefficiency" of the system means that the weight of the lamp doesn't just pull itself down and the weight of the lower unit conversely doesn't just pull the lamp up.

Re: Rise and fall lamp pulley set
The china versions used to have a plugged filler hole to allow you to fill with lead shot or remove some to balance the light and shade. J.
