Legislation is probably the only way to fix it.
For actually necessary amounts of outdoor lighting at nighttime, LEDs are not any more power efficient than low-pressure sodium lamps, and considering how bright LEDs are often made, total power consumption is significantly higher.
The lighting industry has absolutely zero respect for human ergonomics, and is happy to sell as much new lighting as they can as often as they can with marketing spin built on pseudo-scientific nonsense. Surely there must be some engineers in the industry with basic understanding of human vision, but they aren't calling the shots. Policymakers are happy to channel Federal subsidies and local tax revenue through to the lighting industry, tossing out PR announcements about how "green" and "modern" they are being along the way.
