This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Portugal. Not that hot in my town.
And the bulb was inside the house the entire time. I was using it for my desk.
Baked in it's own heat?
I was gonna say the led bulbs I’ve had exposure to get extremely hot. Might have baked the paint
Traces seem ok, maybe wicking enough heat away?
The traces can probably sustain higher heat than that paint. Besides, the hottest part is generally the LEDs themselves.
