The latest C.F.'s have a CRI in the low 80's as opposed to 100 for incandescent. This is very acceptable, but by no means does it meet or exceed incandescent light quality. Much of the improvement comes from the reduction of mercury in the lamp. Less mercury means less of the green spike that is characteristically a part of the color distribution of fluorescent lamps. Mercury has always been a critical part of the proper and efficient operation of the lamp. I am amazed at the amount that they have been able to remove and I would be equally amazed if they can remove all of it, but who knows?

where do you get the info???? it is wrong.
cfl with 6000k and up, have much better color rendering abuility, than incandesants, aquariums, and paint booth, use daylight fluresent bulbs.
but most cfl, are cool white, 3500k.
verilux, is the manufacturer(one of many) of full sprctrum flurecents.
incandesents, aren,t that good, when it comes to color, that is why ge introduced specially coated incd. to have higher kelvin rating, they are called Reveal.
also not all incandesents are the same, there are regular, incd, there are halogen, these two emmit very different light,
there is a bulb for every purpose, general lightning, use cool white, 3500k, for light close to natural , use daytime, aka full spectrum lights. 6000k+
do i use cfl? no, none of my light fixture uses them, all use halogen.(but i do plan on swaping them with leds, my gu10's burn out too often.
