At one point, blue LEDs were super expensive because of their difficult production.
So any product that has a blue LED was considered premium. I guess they were also considered futuristic and high-tech.
Somehow, this is still in the mind of some manufacturers.
All I want is a barely-visible-in-soft-daylight diffused/frosted red or amber LED.
But no, it’s always some 5w lensed blue LED at somehow produces a tighter beam of horrendous blue light that’s brighter than most flashlights.

Veritasium did a bit Why it was almost impossible to Make the Blue LED

Yeah, the history of the blue LED is actually really interesting. It basically exists because one Japanese dude refused to take no for an answer, and continued working on developing them even after his company stopped funding his LED project.

And when blue LEDs just started being available prop designers for scifi loved them because LEDs work much better on screen than incandescent bulbs, and as blue lights were something people didn’t have yet in their household objects they looked new and interesting. Look at the Doctor Who and Torchwood props from the mid 2000s, everything from the iconic Sonic Screwdriver to alien zappers and bleepers and greebles of all kinds were full of tiny blue lights because it screamed “scifi” to the viewer.

Very quickly, though, blue LEDs got cheap enough for everyday junk and manufacturers immediately shoved them into every consumer product because they were new and interesting and, thanks in part to the scifi trend, made stuff look like scifi future tech you could have in real life.

Now, a couple decades on, we’re still kind of stuck there.

You even see them in Christmas lights. They’re so retina piercingly stark, like not a chill light at all (though obv on the “cool” end of the spectrum). I’m out here walking my dog looking at the nice twinkly warm lights - no one wants to see your damned pinprick holes into the Tron dimension

They’re the “literally” of LEDs? Wrong in almost every context but people can’t stop using them?
