Dead LED lamp autopsy.

When I turned on some of my ceiling downlighters there was a slight crackle and one failed.
I don't know if it was the switch that arced or something in the lamp itself, and to be fair I still don't know.
The lamp that failed was one of the Philips 2W LED GU10 lamps that uses a capacitive dropper and a group of four SMD LEDs that each contain about 4 chips.
The only component that had obviously failed was an internal 1A fuse. When bridged with a new fuse (5A because I was hoping for flames) it just worked again.
That leaves me wondering if the switch or a connection arced at power-up and the sustained current transients of the arcing caused the fuse to blow.
Oh well, in goes a new lamp (another Philips 2W LED).
