isn't everyone’s concern potency, density and mass?

time till maturation is determined by the genetics and photoperiod. not so much light intensity.

there is lots of information on this website about cfl's, HID, light intensity and everything else.

it dosn't matter the source of the light, what matters is the intensity. you will be hard pressed to achieve the same intensity from CFL's
harris7 Reviewed by harris7 on . HID vs CFL in a small one plant situation, given light spectrums being ballanced between each situation and all other factors the same, would you see a difference between ~300 watts of CFL, and ~150 watts of CFL supplimented by say a small 50 or 75 watt HID? my main areas of concern are with potency, density, and mass, as well as time till maturation.
