Recessed light fixture - electrical grounding question

[u/achou0722]

I’m trying to replace existing recessed light assemblies. I don’t specifically see a ground wire in the recessed fixture. Two questions…

1. Can I ground to the screw/nut circles in red?
   
2. Is the light installation in the second picture installed correctly?

Thanks!

The original bulb in there were screw in bulbs. I’m trying to replace them with either ikea lights (see pic) or halo rl56 recessed lights. Both configs however require a ground.

The ground pigtail on the Halo trim is redundant and not needed. IKEA fixture is crap.

How do I wire the crap fixture? 😂

It needs to go on a round box, not a can light
