I think you are going in the right direction. If the only thing that enables the angle of the light try another bolt assy. See if you could find a wing nut set up.
The bulb weight 2 lbs but no matter how much I tighten the screw the light slowly shifts down. I have thought about grinding the surfaces with a dremel but maybe there is something better I never thought of.
That first photo shows what looks like a capnut on the hinge. If the bolt that threads into this capnut is too long and bottoms out, then no amount of extra tightening will help. Try a regular nut.

Or just use a thicker washer under the current nut, so it doesn’t bottom out inside the cap. The outer washer is not part of the friction system.
Not a major engineering issue. Go to the hardware store and buy a longer machine screw, a couple of star-washers and a wing nut. The ridges on the star washers will grab the smooth surface and give you more traction. The wing nut will be easier to tighten sufficiently. If there is insufficient space to accommodate the star washers, use your Dremel tool or a flat-file to expand the available space. These are not expensive parts.

Looks like plastic, and to smooth. You won't get it tight enough without possibly breaking it. Most adjustable things have two sides that have ridges that interlock. This has none.

Bolt bottoming out in the cap nut before tightness is achieved will definitely do it.

Originally had a finger turn nut same problem cap nut not bottoming changed to that so I can tighten with spin tigh wrench.
I'm gonna try grinding down one side and try a lock washer
First I'd replace the cap nut with a wing nut or regular nut. Once the cap nut bottoms out, no amount of additional tightening will do anything, except maybe push the bolt through the cap nut (seen that happen with a cheap cap nut). If that happens, then you'll be able to tighten it more.
You might try cutting a small ring of 50 or 80 grit sand-paper and sandwiching it between the two opposing surfaces and that should slow or stop the migration most definitely and wouldn't cost much and is totally reversible. Good luck.
