38 Interesting Facts Because It’s Never Too Late to Learn Something New

I have to admit I have read this fact about six times, and I’m still not sure I understand the science behind it. Why would people invent a blue LED to invent a white one? Is a white LED made of blue LEDs? Do you combine blue with other colors to make white? I am not qualified to wrap my head around this.

Of course, I’m glad about this discovery, as there are many instances where it’s very useful to have a blue or very pure white LED. But I’m one of those people who prefers my lights to be a gentle golden color most of the time. Even if I’m buying LED bulbs, I pick the ones that have a gentle golden tint rather than being blinding white. So this LED invention probably hasn’t benefited me as much as it could have.
