LEDs less efficient than fluoro?? Are we being lied to by TPTB

typical LED 806 lumen lamp under 7 watts

I'd say that's a "no"
Actually if you look carefully fluoros are in the 60-70l/With LEDS in the
50-60l/W range so the fluoros have a slight edge, but its not worth
getting excited about - lighting perception is logarithmic and you wont
notice the difference.

I'm surprised that it's that way round. I thought the whole advantage of
LEDs was that they had higher l/W that fluorescent (and *much* higher than
tungsten!). I've learned something!
