      They get dimmer over time. And they do it gradually so you don’t notice it until you buy a new one and realize how dim the old one was

        Most LEDs run on DC, and the built-in transformer is the most likely component to fail. If the LED is failing and getting dimmer, it’s most likely due to poor heat dissipation.

        If we had little 12v adapters and separate LED modules, you could reduce waste by only replacing the part that fails, and manufacturers would have greater incentive to improve build quality. Instead, we get cheaply manufactured bulb-shaped disposable units that need to be thrown away when one part fails.

          Yeah. Its about 50/50 for the ones who failed me. Gets too hot and burn out or the power supply fails. More prevalent in the compact formats like spots and g8 or g4.

            I have some dc lighting in my basement. It’s great, but there aren’t as many options out there and electricians don’t want to touch it.

              I was looking at rv lighting as some options over wise just doing custom jobs (LEDs in whatever fixtures I think look nice). It helps like domes, reccesed, and ambiant lighting I think.

              Oh yeah electricians are allergic to DC lol (I used to be one, and yeah that was big knowledge gap in codes, breakers, etc).

      Yeah I’ve only ever had one LED bulb die, and I think that was because it was faulty in some way. I’ve had a much better experience with them compared to CFLs.

        Usually it’s a badly designed heat sink that’s meant to cause an eventual short so that it has to be replaced. Or just shoddy low material builds. LEDs really can last an obscene amount of time and they don’t die another part does.

        I’ve had lots of led bulbs die. I think it’s because I bought them at the dollar store.

          And finding quality ones that will last a long time is more difficult than you might think.

          Many of them are made cheaply.
