A little confused!
1) Yes, mercury is a problem and the measures to be taken in case of breakage of these too little known bulbs (do not scattered the vapors by a vacuum cleaner!).
2) Yes, recycling does not always seem right ...
3) No, the incandescent bulbs do not restore a natural light!
4) UV, I don't know. But could easily, if true, be combated by putting the bulb in a "glass bubble" (halogens also emit UV en masse, hence the necessary anti-UV screen (a kind of tube in glass over the "pencil" - for those who have had those old 150W halogen lamps on a stand; often broken by the way, the tube!) ...
5) Headache, etc ... ??? I do not know. I just remember seeing light screens to treat the winter depression (very common in the Nordic countries) with neon tubes (well, tubes wrongly called neon, low energy light bulbs I should say) ...
6) Electric fields: yes. Like a bunch of electrical appliances: transformer [how many transformers in a modern house? GSM, such as wireless, PDA, laptops, low voltage lighting ...], microwave, LED lamps also having a "ballast", TV ...
In short, it is not an "ideal" and "perfect" thing. There are surely flaws. People who find out about this always leave me puzzled.
