Low priced leds, fast shipping
I ordered 10 of these (no longer available from) on June 2cd and received them today. I couldn't wait for the sun to drop to test them out. They are as bright or a bit brighter than the origi...

I question the theory that the LED failures are caused by the boost voltage from the converter.
All of my failures, 3 LEDs going out, occurred in the first week or so of service and at the time I had a Magnetek converter that stayed about 13.4v. I have since, last fall, switched to a PD 9260 converter and no new failures, but I haven't used it that much. This summer should tell.
So, what is causing the failures? Could be poor quality control. Hopefully that has improved in the 2 years since I started switching to LEDs.
It could also be that the series resistors are too small (wattage) and they are failing. I am not aware of anyone having done failure analysis. Could also be cold solder connections.
IMHO, if 3 of the 36 LEDs are out, there is not a big difference in light output and not worth taking them apart. Maybe if I get more failures....
