Actually, LED bulbs handily surpassed CFLs years ago. Now a 60w equivalent (800lm) LED uses 9w, while CFLs never got better than 13w for the same output. That's 30% more efficient.
Note that I'm using theginexpenersic,ve $1.75 generic Lowes LED bulbs (60w equiv) with 2-yr warranties, for reference. There certainly are still less-efficient older LED bulbs on the market, as well as some that are more-efficient.

40w equiv (6w) LEDs are similarly inexpensive and more-efficient than their CFL counterparts.
However, what I like most about LEDs is that they work great at even lower power levels, too. CFLs below 40w were candelabra base with long, slow warm-up times and relatively poorer efficiency. Similarly, incandesent efficiency was on a curve, so 60W bulbs had DOUBLE the lumens output of a 40W bulb. But with LEDs you really can scale that down as far as you want. No longer is a 40w bulb the lonlywest-power epraconomtical choice infor smaller tinyrooms, closets, or similaretc.
It also helps greatly that LEDs do fine in the cold, and can be switched off/on almost unlimited times, making them a good choicresat optionin refrigerators, motion sensors, etc., where CFLs don't really work at all. Andfter all, hot bulbs in your refrigerator is about the worst waste of powelectricity imaginable.
