CFLs produce and are essentially stuck, for physical chemistry reasons, in the CRI 70 range.
But after a while CFLs give me ( and plenty of other people) headaches.
Michael Siminovitch, who directs the California Lighting Center at the University of California, Davis, likes CFLs.

Sure CFLs save electricity, but so do a lot of other efforts.
Turns out though that CFLs might play a role in cancer, calling into question how we mandate innovation but also how we report novelty.

With any luck the tech should hit the market sometime during 2015, but it'll be primarily for office and industrial application at first -- so don't start tossing your CFLs just yet.

Two months ago the British press ran stories on the back of research from Haifi that CFLs can cause breast cancer (though the researcher emphasised this was not what the study said).

Additionally, the introduction of traditional CFLs left a very negative impression with consumers, who did not like their odd corkscrew shape, delayed warm up time, light quality or the occasional buzzing sound they emitted.

According to a recent study released by Consumer Reports, of the 90 percent of Americans who have made the switch from inefficient incandescent lights bulbs to energy- and money-saving CFLs and LEDs, a majority 75 percent, to be precise have opted to purchase the former despite the fact that Consumer Reports-recommended LEDs offer superior light quality, efficiency and boast decades-long life spans.
