Most of the LED street lighting and whatnot I've seen has been more directed than what it replaced. Light pollution has improved, generally. For a while the color temperature was terrible, but cheap and reliable warm phosphors have mostly fixed that. As for private outdoor lighting, I'm not sure that less cost really affects that. People that made poor lighting choices (too much, too cool, too much spill) don't do it because it's suddenly cheap. They just paid more before. The answer to this is likely some degree of local regulation.
