Wouldn't it be better for the LEDs to not burn out in the first place? Because this was and is achievable.

- stavros 3y agoThat is an orthogonal concern, the two aren't really comparable. It would be good if the LEDs didn't burn out, and it would also be good if we didn't have to throw away both parts when one failed.
- lstodd 3y agoI can't agree with this. If we're redesigning the power supply it's actually much cheaper to make it not cause burnout on the LEDs than to make it replaceable.
- stavros 3y agoIs it less half the cost? If not, I'm in the red as soon as one power supply (or its LED) dies.
- lstodd 3y agoDepends on how hard you are prepared to cut the cost. If you're designing for cheap LEDs, then it might be up to 80% of the cost. But it's worth it because even cheap trash LEDs will last tens of years. If you go for good nice LEDs then maybe 50%. This would be indestructible, but it will cost you.
