Technology
The two major innovations of the unit were the high-frequency ballast, which gave the lights greater intensity and eliminated flicker commonly found in off-the-shelf fluorescent tubes, and the Kino Flo tubes, which contained a number of special phosphors designed to eliminate the characteristic tints in the magenta-green spectrum which are present in most domestic fluorescent lights. Since the type of tube determines the color temperature, any Kino Flo lamphead can be quickly converted between daylight and tungsten balances by simply changing out the tubes. Mid-range color temperature can also be created by mixing tubes of both color temperatures. Kino Flo have also expanded their tube line in recent years, creating visual effects tubes optimized for bluescreen and greenscreen spectra, as well as a variety of other shades for general color effects.
