I'm in a nasty frame of mind right now, and this is what my 'tism brain decided to laser focus on for several hours. I'm mad that my light bulbs cost 10x more than they used to, and don't last any longer, and my power bill is higher than ever.

Yeah yeah, I know, it's probably just capitalism shitting it up on purpose for profit. And bulb science is probably solid, I guess. I'm just pissed off that I just barely managed to scrape through this pay period with $2.78 left in the bank before I default on my mortgage.

Anyway, any lightbulb science comrades got any info?

They get too hot and the 0.07$ capacitor they put in it dries out and dies. You want the 0.09$ capacitor which lasts 1000 times longer, but usually they only put those in the 45$ led bulbs.

You can do like me, when they die, take them apart and replace the capacitor with a super deluxe 0.11$ one !

Holy shit I never thought about what's inside an LED bulb past the LEDs themselves.

It's an AC to DC step down voltage regulator and then a multi channel constant current regulator to drive the led and the current setting is changed by a microcontroller which usually has a Bluetooth or ZigBee or ism/315/433/915 MHz or infrared transceiver for communication with your phone / remote

Occasionally, for bigger lamps, they do need actual cooling fins though.

Yes, anything above 15watt needs heatsinks for sure
