it turns out that the Litake brand which I bought first doesn’t quite reach long enough into the socket to get the threads to meet, and so I had to return them to get the LOHAS brand.
I came across a problem like this before, and it was kind of a manufacturing/assembly defect. The contact at the bottom of the socket is meant to be bent up to give a bit of spring tension to connect to the bulb, but mine were basically flat. You can take a tool (what worked best for me was a multitool’s can opener) and bend the tab up more so it can contact bulbs that don’t screw in far enough. UNPLUG IT FIRST though

Sounds scary, but thank you for the model of what’s actually going on!
