What's inside an LED bulb?
We took apart two LED lightbulbs, a CREE LED bulb from 2014 and a Philips bulb from 2018, and compared their build quality, the electronics, and their overall design. It was fascinating to see the differences in approaches they took and the challenges they faced with rectifying the incoming power and also keeping temperatures reasonable so the electronics don't fry.
