I've been using the Ideal Lume for many years now; there is lots of info about "bias lighting" on the company's site.
their fluorescents give off light at 6500K, which is the color temp at which TV's are calibrated.
this kind of lighting is used in tv studios as reference lighting for quality monitoring.
if one uses lighting of another color, it will bias the colors as perceived on the screen to another color temp and falsify the tv's colors.
(not very easy for me to explain clearly now, hope you understand).
a major benefit of using bias lighting is that one is not blinded by a bright tv screen in a dark room, it's not fatiguing to the eyes.
