I'm stunned that a 1,000uf cap fails and a 470uf cap works, that makes no sense! I've actually tested that circuit with a 2,200uf cap to see how long it would hold the LED's up, and it didn't change the operation, and it never even occurred to me to think it might!

FWIW, my previous production run of the lighting boards had a 680uf cap, that worked just fine. That was going to be my standard going forward, but I couldn't get them for the latest production. The electronic parts shortage is biting everywhere. I had to settle for a 470uf cap again, the largest value I could get in the form factor for the production board.
