Incandescent light bulbs are officially banned in the U.S.::America’s ban on incandescent light bulbs, 16 years in the making, is finally a reality. Well, mostly.

      This… Doesn’t seem right? Dimmable LEDs are switched hundreds of times a second as would the resistors and other components in series with them. Computers turn on and off transistors (mosfets) millions of times per second. Dude flipping a switch a few times isn’t close to that.

      Heat is the worst enemy of most electronics. Many LEDs are put in places where heat is not dissipated well which can shorten life span.

        Excessive heat perhaps, and yeah, bulbs with bad thermal design, or bulbs installed in tight enclosures do die a lot faster.

        It’s also temperature changes that cause problems. A current that flickers 50-60 times a second is not going to fluctuate it’s temperature. Turn it on or off every 10 minutes and the components will shrink or expand each time, and the components will eventually start to fail.

      Yeah that occurred to me like in the middle of the thought process and I just rolled with it. 😅 That apartment kitchen was so dark I turned the lights on a lot.
