TRUE MATCH lamp colour is uniquely formulated by Kino Flo to match the spectral sensitivity curves of film & digital imaging equipment. High output tungsten & daylight versions (CRI 95) are available in sizes that range from four inches to eight feet, & yet the quality stays consistent within the True Match line. They are soft, energy efficient & cool to the touch. True Match lamps work side by side on the set with traditional tungsten & HMI fixtures without filtration.
