Emulate a bright summer’s day, fall’s ruby sunsets, or a soft winter’s glow instead of headache-inducing fluorescence. Fluorescent light is known for its harsh glare and imperceptible flicker that can cause headaches, eyestrain, and anxiety for some people. These light filters can smoothe out the edges of jarring fluorescent light in your classroom to create a more peaceful learning environment for your students. Simply attach the filters’ strong, sewn-in magnets to the perimeter of standard overhead lights and see the colors of your classroom transform into a soothing atmosphere for you and your students! Fire-tested filters are protected by a flame-retardent coating that will keep you and your space safe. Set includes one filter of each seasonal pattern: summer, fall, and winter. Each filter is 4"L x 6"W; 1 lb.
