Details: American Permalight UL924 ETL-listed EXIT Sign, Outdoor-use, 100-foot Viewing Distance LED ACTIVATION

UL924-listed by Underwriters Laboratories Inc for activation by LED (Light Emitting Diode) lighting at 100-foot Viewing Distance. Surface, flag or ceiling mounting (hardware included). Each sign comes with two snap-in chevrons < >. Your advantage: just order the total number of signs needed and snap-in (and thereby cover if needed) the left / right pointing directional indicators when it comes time to install the sign on-site. There is no need to specify the < > direction beforehand. Before installation it must be determined that there is a minimum of 5 fc (54 lux) of LED, fluorescent, mercury vapor or metal halide light on the sign face(s) at all times of building occupancy.
