I can’t figure out that retaining ring on the driver? Is there even one there??? And does it turn? I was looking thru a magnifying glass and couldn’t really see a ring like on other lights.

Below is a very clear picture by TomE of the ‘driver retaining ring’. It is very, very thin saypat & somewhat hard to see… but it should be there.
HERE is some more info.
