CFL's are inherently technically challenging to dim. Not 
impossible, but have problems.

LEDs are inherently technically easy to dim, either by 
average current limiting (not preferred) or by PWM ing at 
fixed peak current and variable duty cycle. Given the 
attractiveness of dimming capability and the ease of 
implementation, most significant manufacturers will almost 
certainly provide the capability.
