These cozy green shades help filter out annoying hues in classrooms or cafeterias, softening the light for a cozier space. Designed for standard fluorescent fixtures used in schools and office spaces. Includes set of 4 flame-retardant 54 x 24 inch (137.2 x 61cm) panels. Six magnets allow for single or double swags on each fixture. For those with sensory processing disorder, the filters greatly reduce and soften the "strobbing" effect that can be experienced from fluorescent fixtures.
