I really like the Philips Sun Filled LED lights. I have a stockpile of incandescents, and they're the first one that's come pretty close that I've found that's worth replacing them with.

Policy-wise, lighting, post LED transition, is a small part of overall energy consumption. Trying to squeeze efficiency even harder isn't going to accomplish much, and it will only annoy people more and if this article is true, maybe damage their health.
