Samsung (etc) caught with their pants down

It makes you wonder how much longer it would take to commercialize blue LEDs without his contributions.

I didn't watch this, but i bet technology connections video about blue Christmas lights is more entertaining!

All of them! I like Veritasium though, not every video is a banger but this one definitely is

I freaking hate blue LEDs.

I actively avoid buying anything with a blue LED because they are so obnoxious. So bright. Why do I want to read by the light of my HDD? Does this video explain why they have to be like that?

Maybe if you have a separate wing of the mansion to do computing stuff it is not annoying. But if like a lot of people you have electronics in your living space, these lights are extremely disruptive.

It seems that can't really be dimmed.. I had to give up on a couple of blue backlit alarm clocks because there is no way that the time can be visible without illuminating the whole area around them.

For whatever reason, red is the best one. I would prefer another color aesthetically. For whatever reason, red is the only color that does what it has to do and nothing more.
