Interior LED Fixture has Dimmed
Without any preceding symptoms, the under cabinet LED fixture in our galley has suddenly dimmed. Seems to be maybe 2/3 of its original full intensity. I dropped the fixture down from under the cabinet...

I would first check the individual LED chips in the lamp. You may have lost some. Can you swap it with one from elsewhere in the coach?
A .2 volt difference around a coach isn't unusual, probably means a less than perfect connection somewhere, or how you held the VOM probes. I would be more interested in the voltage measured at the battery and compared to elsewhere in the coach.
Interesting that in recent weeks we experienced a failing LED fixture in our home. Went through all the testing and isolating, etc., and it turned out that a two year old interior LED lighting fixture simply had failed. (Its symptoms were dimming and flickering.) Probably due to failing diodes, I suspect.
In this case in our TT, each and all of the LEDs are illuminated and burning steadily albeit at maybe 2/3 intensity. So first step for me is I will re-crimp a solid connection and then ultimately swap the failing fixture for a known good one. Sort of like I've tested and repaired IT stuff over the years.
Sort of reassuring that a variance in voltage readings around the TT isn't unsettling. The way these things are put together I wouldn't be surprised that there is a less than perfect connection somewhere in the wiring harness. Unfortunately, I cannot trace this circuit very far . . . although the "Sherlock Holmes" in me wants to give it a shot! ;)
