Yeah I really don't like the proliferation of blue-pumped LEDs, they're environmentally friendly from the narrow perspective of energy use but they make the lived environment much worse in other ways, particularly the horrid clinical high-K ones people who want to make a 'modern' ambiance love so much.
In my view we should simply have improved on what already existed, instead of blue-pumped LEDs we should have used monochromatic amber ones like the SOX streetlights which were once ubiquitous in the UK. Night actually looked like night back then, rather than a cheap and nasty approximation of daytime.
It's so interesting that people assume the color of sodium lamps is the color of night just because that's the color technology made it at one brief moment in time. Just goes to show that illumination is culture, just like everything else
it might also have something to do with the orange glow of the sodium lamps resembling the orange glow of fire and torches, which were the primary medium of lighting in the dark for humanity for thousands of years

They are friendly in the same way the feeding a baby petrol is. Sure it's more energy efficient, but humans aren't machines where input = output. It's going to take decades to get rid of all of them, and then even longer for all the cancers that blue light causes to work themselves out. It's amazing that we invented a new asbestos and put a green wash on it.
In people for what cancers have been investigates there is also evidence of a link, but not enough studies have been done to say that it's the case for all cancers. This is absense of evidence rather than evidence of absence.
Interesting, thanks for the links. To be honest I'm not scientifically or statistically literate enough to know what to make of that beyond that there might be possibly something there, maybe.
From what I've seen, most of this energy-per-lumen efficiency has just been funneled into outputting more and more lumens, not actually saving energy. It's only going to get worse with the new 2027 regulations coming in.
