The 4′ and 8′ models are each 3-wattage and 3-CCT  selectable, replacing up to 9 dedicated wattage and CCT models. The sealed fixtures  are moisture, corrosion, and rust-proof, with IP65 rating. The fixtures have an extruded opal prismatic lens with UV protection and a 110-degree beam angle. The end  caps are constructed of white polycarbonate. These luminaires are ceiling-mounted with a quick-mount back plate for easy installation. They are both cETLus and DLC Premium listed.
