Our tube guards are made with polycarbonate material to get the cleanest, clearest, streak free tubes in the industry. We maintain a comprehensive inventory in our two company warehouses to include UV, color and matrix tube guards. Our extensive line of fluorescent lamp protectors (tube guards) range from matrix & all colors of the spectrum to clear poly carbonate. We use a copper screw shell socket for better connection and smoother application.
