GamTube
GamTubes™ are colored filter sleeves that slip over fluorescents to correct or change their color. They're an excellent and economical choice to simulate neon, reduce glare or to color correct for motion picture and television production. GamTubes™ are available for every fluorescent lamp from T-2 to T-12. They're also available for biaxial & compact fluorescents lamps, requiring only trimming of length, which is easily done with scissors.
