I made five ceiling lights for above my kitchen counter. They're built using DN50 PVC pipes. I DIY-ed the mounts in white PLA, keeping them low-key. I 3D printed wire guides to center the tubes perfectly straight. The mounts have threads, making setup and takedown easy. They fit on a regular drywall electrical box, too.
They're set up for GU10 bulbs in these fixtures.
The LED unit, at DN32 diameter, tucks the bulb inside the pipe, so it's not too bright.
On the pictures, we do not see the final. paint job is in progress.
If you like it, give a thumbs up!
