Abstract
A variable color filter for fluorescent lamps has a color tube supporting colored filter strips disposed longitudinally along the color tube so that the strips are circumferentially adjacent to each other. A motor rotates the color tube inside a mask so that an aperture in the mask limits emission to light filtered by only a circumferential portion of the color tube. A controller positions the color tube in relation to the aperture to achieve a desired coloring of light emitted by the lamp tube.
