Comment on How come LED Light Bulbs only last for about 2-3 Years?

  How so?

    Just Google “how to increase my fire risk to save $2 on a new LED”. Should be a how to guide or two out there.

      Some people like tinkering. Big Clive for a series of videos on Dubai led bulbs. The government mandates that the bulbs be extra efficient and last extra long, so they are built with more filaments driven at a lower current. They run cooler and last longer. You can do a similar thing with American bulbs if you’re handy with a soldering iron.

      Honestly, with how poor many of these things are mass produced, opening them up yourself is practically a personal form of quality control. Whether you modify it or not I bet it’s less likely to die prematurely or burn your house down than those of a regular person who doesn’t open them 🤷‍♂️

      No, shorting a dead LED in a series chain of 10-20 will NOT burn your house down, it’s barely a difference to the driving circuit. Unless you’re buying knockoffs, there is a fuse in the base that will blow at like 0.5 A, no matter what you do to the circuitry.

      In many bulbs, you can adjust the value of a current-sensing resistor (usually one or two in parallel, about 2-30 Ω) to make your own “Dooby” lamp with lower power and way longer life. Of course, you need to know something about electronics.

    Well I’ve done it just twice, I don’t even remember what I did, I just soldered things that seemed broken.
