led lamp, interesting construction.

You were testing some of the leds backwards, look at the printing on the circuit board. Short the burned led and the rest will probably work. It looks like they snake from left to right then left again as you move down rows 👍🏻

Nice teardown. I was wondering if you worked out if all those LEDs were in series, or groups of LEDs in series, the groups being in parallel

[@mathewlawrenceml]

They're all in series.

Buy a tripod !

[@mathewlawrenceml]

I have one. It's broken.
