If LED bulbs are supposed to last for 10 years, why do I still need to replace them every 9 months? (hexbear.net)

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?

LEDs should not get that hot. That’s literally a part of the technology

The LEDs don't particularly (unless it's a very powerful one), their power supply does though. LEDs run on DC voltage, so they need a converter from the AC line voltage to not die instantly
