The legal requirements for emergency lighting include exit signs no further than 100 feet from any point on a path of egress. Additionally, they must be placed over every door and turn in the path of egress. The MINIMUM illumination requirement has three criteria: 1 footcandle average, .1 footcandle minimum, cannot exceed a 40:1 max/min ratio.

Emergency Lighting is required for every building type except single family dwellings. In these buildings it is required for the path of egress that will typically include stairs, aisles, corridors, ramps, walkways, parking lots, escalators, exit passages, and outdoor pathways.

Exit signs have been LED for many years and are typically monochromatic red or green, but in some cases a white LED source is used. For emergency lighting units, most of the portfolio is now available with an LED source.

Emergency lighting products are made for commercial indoor, industrial, and outdoor environments. Commercial indoor products are typically damp location standard with a temperature range of 10-40°C. Industrial products are typically damp, wet, NEMA4X, and hazardous rated with standard temperature ranges of 0-50°C with some covering -30°C to +50°C with a cold weather option. Outdoor products are wet rated with standard temperature ranges of 0-50°C with some covering -30°C to +50°C with a cold weather option.
