Light socket to outlet adapter not working
I find this with cfl lamps quite often and think your adapters have the same issue.
The problem in most cases the center conductor is not touching.
But they worked last year the same fixture and adapter.
The center tab quite often gets folded down sometimes because of a extra tight light bulb sometimes because of heat.
The fix:
With the power off!  pulling the tab away from the fixture or lifting it a little bit has always fixed this issue for me, 150w incandescent lamps were really hard on fixtures and this method worked on them even with the “high current draw / heat”.
Don’t get crazy it usually won’t take much just a 1/10 of an inch or possibly up to 1/4 but that will usually fix this problem, give it a try.
Again with the power off raise the center tab it is usually a brass colored metal tab that is bent, just straighten so it contacts the adapter.
