They way I understand it this report in another ignorant media
grandstand based on ancient information.

Colour spectrum of light can be an affecting part for SADS and other
mood disorders. Fluorescents are usually the lights that people sit in
front of to alleviate these symptoms. The daylight and high K ratings
are much better than incandescents, typically.
Hell, I and many other lay in front of huge wattage fluorescents to
get tanned and rid ourselves of skin eruption due to excema and
psoriasis. This is a recognized medical practice that has now erupted
as a cancer preventative, also.

The 60 Hz flicker was another problem with fluorescents that has been
alleviated over the last few decades by longer persistence phosphors
and with the high frequency electronic ballasts the flicker
disappears.

My understanding is that epileptics have problems with strobing lamps
interfering with their alpha rhythms, putting them into a beta wave
state. Beta states are from (guessing from memory) 10-12 Hz and up.
Electronic inverters certainly are not in this range. Possible 25 Hz
incandescents and entertainment strobe lights are for sure, as well as
some film sequences.
