Still, down at the table surface, the LEDs are brighter than the CFL spot lights.
The more I used these, the more I like them!

The operating principle of a CFL make them best at diffuse lightning. In fact, to replicate the SPOT function of an R20, R30, etc... mirror are use that lower significantly the efficiency of the bulb. However, at 40 to 50 Lumen/Watt, the CFL PAR 20 are still 2 to 2.5 times more efficient then an incandescent light.
The operating principle of LED make them generate concentrated light.... Even LASER concentrated light if so desired. Consequently, for most lightning requirement, the LED generated light need to be diffused in order to be pleasing. This is a relatively easy function compare to "Concentrating" the light.
Consequently, it is only normal that the LED will overtake the SPOT MARKET before any other market.
