Incandescents have a great CRI, 99+ for standard bulbs, as shown in your own article.

The old style yellow-toned fluorescents exhaust people. They strain the eyes too way much. Replacing them with the newer style pink-toned fluorescents helps with that a lot.

I find that many will buy the cheapest available and then be disappointed... especially when I comes to lighting...

Proper lighting is a science once all factors are considered.

I keep hearing incandescent bulbs are hard to find, but I blew a 60 watt bulb last week, walked to Kroger and picked up another pack of 2 60w bulbs.

Yes its like the difference between digital and analogue.... Analogue is real and beautiful,the other is flat and voidish!! (Offers nothing)

i've been to lots of neighbor homes where they still use incandescent lights. I'm exclusively using cfl and led and my electric bill is much lower than theirs to the point where they wonder how I can have such a low electric bill but then again, these are the same folks that keep their homes at 68 all day long even when the house is empty during the summer.

I've just learned something else about fluorescent and CFL lights. The older versions of them that had magnetic ballasts, produced a 120-Hz flicker that was known to cause difficulties for persons suffering from some types of disorders, such as autism and Lyme disease and others. Perhaps persons without any special problems might also have been affected. But fluorescent lights that used non-magnetic ballasts eliminated almost all the flutter. It's likely that the college lounge where I long ago made the observations I described earlier, was using the type which had magnetic ballasts.
It absolutely does flicker, you just can't see it because as you said it's fluctuating at 60hz a second. Even the CFL will continue to have a glow between sine waves.
