@Gargron@mastodon.social you can’t really complain about leds being bad compared to sodium lamps for CRI reasons, low pressure sodium street lamps have a -44 CRI. Which actually does have benefits since it contributes to efficiency and reduced light pollution, but i didn’t even realize that CRI could go negative until i saw sodium lamp figures

@timmy@goblin.camp @Gargron@mastodon.social I think the point was that high pressure sodium lamps are fine because we don't care about or want high CRI values for nighttime illumination.
