Wild. I build homes and I’ve seen quite a few things short out. It can happen with age. As long as everything is wired correctly, not usually something that causes a fire. Puts itself out. Some of those older LEDs can produce more heat, overtime it can cause say the solder that holds wiring together to come loose and ground out persey on your ground or neutral. 

I was mid remodel last week, flipped on a light switch in a bathroom, and poof a bulb kinda did something similar. Not too common, but happens


Stay humble, stack sats, upgrade those bulbs 😘
