Not exactly. I'm looking for single fixtures.

This is kinda what I want, but alas its not dimmable.

At least not by plugging into a dimmer.

When I buy new art it turns into a 30 minute thing of me hanging it, stepping back, and then readjusting. And that's if I already know where I want it to go.

If I don't have a place for it I can spend an hour moving things around to get it just right.

My tip is to hammer small nails, hang it, stand back and observe. Then just keep moving things till it works.

I think accent lights are necessary for wall portraits. Something like this

Along with a spotlight LED from a hardware store is a must. Otherwise overhead lighting is used and it sucks.
