I went to 3 ReStores yesterday (Santa Ana, Anaheim, and Bellflower) and they were all pretty much like what you described. Modern residential lamps and fixtures from large donations, and mostly LED bulbs. Some incs but modern ones from just before the ban. Bought nothing. Total bust. Last score was a few weeks ago at another ReStore in Oxnard and got a bunch of NOS Luxor incandescent bulbs. Scored a few new fluorescent and HID lamps at others.
This has been my experience with a lot of Restores now too. The two in my city have been like this since ~2019 or so. A lot of the lamps (mostly LED) they're trying to sell aren't any less expensive than they would be to buy new. As of now, I've found that Restores in smaller towns and cities usually tend to have more interesting stuff.
