The EOL looks like a pulse-start MH lamp hot restrike.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

the socket shrouding the heatsink probably did not help.
at least it has one.
so they tried to make it last.
time to autopsy it!
bet the cheap caps gave up.

@toomanybulbs: I guess that's what happens when you use one of these outdoors.
And i bet something in the driver failed because all of the LEDs look like they did not fail. [No black dots]

Old lighting is, and will always be, the best lighting.

I'm going to replace the capacitors with ones i have on hand, see if that fixes the problem.

I replaced all of the capacitors in the LED light and nothing changed.

@dor123 I don't see any physical problems with the LEDs but i guess it's worth a try.

All of the LEDs test fine.

Did you check the fuse resistor also? Sometimes these cheap resistors go open from crack in the resistive material.

@ResR: Then why are the LEDs blinking?

Turns out the LEDs in this LED bulb are failing and the driver is still good. (I figured this out by connecting the LEDs to a 12v power supply)

The LEDs seems to work fine at really low current but at higher current they begin to flicker badly.

I have another LED bulb similar to this bulb that the driver in it failed, (i knew it was the driver because it left a big skid mark inside the lamp) so i decide to put the driver that was in this bulb into the other bulb and got the other bulb to work.
