I spectrum analyzed both CFD and LED lights and neither carry anything resembling a full spectrum. They just appear white because the frequencies they emit trigger all 3 of our color receptors.
Basically they have the same problem - converting either deep blue or ultraviolet light to lower frequencies by fluorescence, but each component in the fluorescent dye only produces light of a single bandwidth - one color. You need a rich mix for a good spread.

That said, normal incandescent bulbs lack in blue and purple. Even a 'warm' colored LED brings out blue details better than the old stuff.

I replaced my last CFD lamps with top tier LEDs - finally some that outperform them in lumen and don't fail within a month or two... and they only get lukewarm, where the CFD's got scorchingly hot.
