Need idea for ceiling light

Hi folks. I'm new to this forum.

I'm trying to build an adjustable, articulating ceiling light that will sit above my desk. Something like this: http://lampegras.fr/_medias/pic_tiixsgwg.jpg

My challenge is finding the swivel hardware that connects the light to the ceiling. I purchased a variety of swivel parts from a lighting parts supplier, but they are made for small lamps and cracked when tightened.

I then bought a shower head and stripped out the ball and socket part. It worked better, but I still can't tighten it enough without the socket cracking. an industrial strength ball and socket like the shower head would be perfect. I just can't find anything like that. McMaster-Carr is my go-to site for unusual items but I couldn't find anything there either.

BTW, I tracked down the French company that manufactures the above light. They sent me to their U.S. distributor who charges over $1,000 per fixture. I really just need the ceiling hardware, which isn't sold separately. I have already constructed several models, one with metal rods, another with walnut arms and electrical parts from a $20 Home Depot desk lamp. I could certainly finish this project with a fixed connector, but I really like the flexibility of the swivel for my particular use.

Thanks for any ideas.

Rich

How far down from the ceiling are you go? Here is a link with a swivel fitting although it is for a wall mount they may have other ceiling mounts,do you already have the fixture? Low voltage track lighting also offers some options.

You can also try searching online for "articulating arm". Articulating arms are used in industry so they are available in different "weights", strengths and prices. Some are complete arm assemblies while others are sold by individual pieces so you can custom build for your application.

Thanks for your responses. To add some perspective, here are pix of my rough models. The version with maple arms is connected at the ceiling to a door bracket from an old garage door opener. I drilled through the bracket and arm, and inserted a bolt, washers and a large wing nut. the idea is to create enough friction that the arm stays at whatever angle it's moved to. The two square pieces of maple are separated by a fender washer so that I get 360 degree rotation. It's not elegant, but it seems to work. If I go with this model, the wires would be buried in grooves and covered with matching wood splines and I would use LockTite to keep the wing nut from coming loose.

This version uses the ball-and-socket part of a shower head. Much cleaner, but I can't crank the socket tight enough to keep the arm from moving without cracking the socket. I'm using 1/4" galvanized pipe, so maybe I should switch to maple.

I don't have wall space in my office for a wall-mounted light, so I'm hoping to make the ceiling mount work. Any new thoughts after seeing what I'm trying to do?

Thanks,
Rich
