Philips claim their Calculite LED light generates 1200 lumens for 18 watts and that CFLs require 33 watts to do the same.
This is untrue: according to the dotlight.de catalog, CFLs can generate 1200 lumens from 20 watts.
Therefore the Calculite is only about 10% better than readily available CFLs, not 40% as they claim. It will probably cost 10-20x as much - why would you bother ?
Stick a directional luminaire on a CFL and you will be in business.
Leds are great, but they are not yet ready for "bulk" lighting.
