Looking at the latest study I could find by the US DOE (published in April of 2012), it does appear that many LEDs are finally becoming as efficient as CFLs, in terms of lumens per watt. The DOE study (PDF here) shows a mean of 60 lm/W for LEDs tested, which is comprable to CFLs. There is still a wide variance from one LED lamp to the next, though. The best ones do surpass CFLs in terms of lm/W, but many do not. That study also reviews actual output compared to what retailers claim, which is interesting to read.

I just found this out today: LED bulbs are *not* actually any more energy efficient than compact fluorescent bulbs, according to http://blogs.law.harvard.edu/philg/2012/11/23/things-that-i-didnt-know-about-led-light-bulbs/
