IMO, the switch from sodium lamps to LED lamps (one of the article's gripes) was for a good reason: lower use of electricity. I also happen to think that the light from sodium lamps looked ugly--much worse than a properly working LED lamp--but maybe that's a personal opinion. (I would also question the study that "showed" white light reduced melatonin production, but that's a different issue.)

(Re "properly working LED": apparently many street lamps in the US were built by a single company, and that company's bulbs are prone to turning purple over time. But that wasn't a reason not to make the switch back when, because at the time no one knew this would happen. It's being fixed now by replacing the purple bulbs with better quality LED bulbs.)
