Non-parabolic plastic louvers are a very economical solution to many lighting and luminous ceiling applications. These louvers are molded in polystyrene or acrylic materials. The white panels are translucent and provide uniform illumination throughout the entire surface. Open cell design allows the light to be transmitted to the working area while reducing glare; in addition, this louver allows nearly unobstructed air movement which will increase the bulb and ballast longevity through more efficient heat dissipation. The eggcrate louver is approved by UL for use under sprinkler systems and can be used in lighting fixture or luminous ceiling applications. The eggcrate product is an efficient and economical light control device which will reduce glare and provide effective lighting.
