Snap-on LED Work Light Malfunction

(1/5) > >>

Smoky:
I'm doing some foundation repairs and the customer let me use two of their work lights to brighten things up in the basement.



One of them worked for about two hours and then started to flash on and off, and after a few cycles of this, the light doesn't want to come back on:



All of the LEDs shined bright when it worked so it must be something on the board that has failed:



The lights appeared to be in brand new condition but after a little research I found out that these were made around 2014 or so.

The construction quality of the light is very good, thick glass, no burns on the board, so probably worth a little time and effort to fix it. Plus, it was free ;D

Why would you draw that conclusion?

Check the output from the board for a start, if there's nothing there, then it probably is something on the board. Otherwise LEDs can and do fail.

Don't Snap-On do lifetime warranty on their products any more?

Xena E:
BTW.

Did you have a premonition that the lamp was going to fail, and thought that you should video it?

Smoky:
There are 46 individual LEDs on the face of the panel so I couldn't imagine all of them failing at the same time so that's why I concluded that something wasn't right on the board.

When I was troweling cement the work light started to go on and off so I picked up my phone to capture how it was acting up. I thought it would be a useful video while explaining the problem on EEVblog, my go-to place to get answers relating to electronics :-+
