"Since LED and CFL lamps both have similar efficiencies you would need roughly the same wattage for both. "

I'm not sure, but I think LED efficiencies are getting better, in this case at least.

The 50Weq CFLs that I removed from the kitchen, each used 11 watts,
These 40Weq LED lamps are brighter and use 7.5 watts achieving 450 lumens @3000 K (using 32% less power?).

50Weq CFLs? Not so good..
Light Output (lumens) : 380 lm (15% less than the 40Weq LEDs?).
Actual Color Temperature (K) : 2700 K
11-Watt (50W) Flood CFL Light Bulb (E)*-BPESL11R20/DM/ESM at The Home Depot

And, LEDs are getting a little cheaper now.. But, with me it's not about price.
For some reason, I'm attracted to efficient gizmos!!
