I know that CFL's don't just go out they get dim as they get older, but by being dim are they actually using more energy to stay lit or less energy?

Measurements that I have made on a number of CFLs suggest that in practice, that the power consumed does vary much much during life.
At work I use large numbers of 15 watt CFLs, I have measured the power used by new and well used examples and found it to be a little under the nominal wattage for both new and used lamps.
