    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.

          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. 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.
