The X-21 Lensgard™ Component Assembly from RLR Industries, represented to lighting OEMs by Bill Brown Sales, is engineered for performance in high-abuse environments. This rugged composite lens solution combines proven optical control with exceptional impact resistance—helping OEMs design luminaires that withstand demanding applications with reliable performance built-in.
Each assembly integrates a K-12 diamond prismatic acrylic lens with a smooth, clear polycarbonate shield, delivering both light transmission and protection. A specially engineered extruded acrylic channel seals the perimeter, sonically welded to create a single, unitized lens assembly. The result: a vandal- and impact-resistant solution that safeguards fixtures while ensuring long service life.
