These injection molded lenses are manufactured using clear acrylic and clear polycarbonate. The polycarbonate version provides protection of the light source against abuse, such as severe impact and vandalism. This new 12×12 version is intended for use with existing die cast housings, such as the QSSI VN41. The prism structure provides excellent lamp hiding power and improves the distribution for better uniformity.
The Series I43 12x12x5.5 Security Lenses are suitable for interior and exterior applications. The NEC requires luminaires listed for use with metal halide lamps to either utilize an open-fixture rated lamp or a lamp containment barrier. Records of this testing are the responsibility of the luminaire manufacturer. The reflector/housing design will impact operating temperatures. Thermal testing is advised.
Before final installation, dissipate static on parts by spraying with de-staticized air or by wiping with a clean, damp rag. This will help minimize dust build up.
