Below diagram shows the spectrum a LED lamp (blue), a CFL (green) and an Incandescent (purple) superimposed the solar spectrum (yellow).
Note that the energy used by each lamp is at least the area underneath its curve. You can see why LED lights are more efficient than incandescent lights and CFL lights.
More importantly, if you compare the spectrum distribution in the visible light range, LED lights are much more evenly distributed than the CFL lights. It is closer to the spectrum distribution pattern of natural light.
