This is mentioned in the article: the new streetlights are going to be at 3000K, between the 2200K of the sodium lamps and the 4000K of normal LED streetlights.

This is mentioned in the article: the new streetlights are going to be at 3000K, between the 2200K of the sodium lamps and the 4000K of normal LED streetlights. It looks pretty good to me.
- jacobolus 10y ago3000K is still not great. I would prefer they cut the light from the blue diode entirely. But 3000K is much better than the 4000K version. “Color rendering index” is an absurd standard for nighttime lighting. (Not to mention a hacky ad-hoc metric from a few decades ago which is pretty terrible for any purpose, but that’s another story.) Someone should make a “night vision clobbering index” by which to judge the SPDs of outdoor lighting.
