Inside MR16 12V LED bulbs
🕑 Added 2023-09-03 13:33:07 +0000 UTCI may switch to using the word "bulb" instead of "lamp" as there seems to be a cultural variation.
This video was filmed on the fly while travelling. How does the black background look, and how are the acoustics?
The schematic shown was featured in the weekend live stream.

B is an abbreviation for BigCliveCombobulator
The "B" component could be a ferrite bead for either general noise suppression, for spike protection the protect the diode. I could see this working from 12VAC or 12VDC almost equally well. I've worked on TV sets (CRT based). I remember one time when I tried replacing a fast recovery diode with a general purpose power rectifier, somewhere in the horizontal sweep circuit operating just under 16kHz (US NTSC). It didn't survive the first power on.

For the average American the word "lamp" means a light fixture (wall lamp, ceiling lamp, etc.) or a table lamp or floor lamp and one tends to use the term "lightbulb" for a replaceable component that produces light. Whereas to an electrician, the term "lamp" usually refers to the lightbulb, not the fixture.
