Emergency lighting is required throughout the path of egress and must operate for a minimum of 90 minutes. (See NFPA® 101® Life Safety Code®.)
Stairs, aisles, corridors, ramps, escalators and passageways leading to safety must be continuously illuminated for a minimum of 90 minutes. Illumination times for Bodine fluorescent emergency ballasts, emergency LED drivers and emergency lighting inverters meet or exceed the National Electrical Code®, Life Safety Code® and UL 90-minute requirements. For codes requiring longer illumination times, Bodine offers models with two- and four-hour runtimes.
Emergency lighting transfer must be automatic.
Transfer of emergency lighting must be automatic (within 10 seconds) of loss of the normal lighting supply power. Bodine fluorescent emergency ballasts, emergency LED drivers and emergency lighting inverters provide instant backup lighting when the normal supply of power fails.
Emergency lighting must provide an average of 1 footcandle initial illumination.
Emergency lighting facilities must provide initial illumination that is no less than an average of 1 footcandle (10.8 lux) and a minimum at any point of 0.1 footcandle (1.1 lux) measured along the path of egress at floor level. A maximum-to-minimum illumination uniformity ratio of 40 to 1 shall not be exceeded to minimize dark-to-bright spots. Proper placement of Bodine products will help ensure code compliance with regard to footcandle illumination.
Changes in direction must be clearly marked.
Changes in direction or routes that are not immediately apparent must be clearly marked. Specifying Bodine products in addition to other unit equipment helps ensure an adequate level of safety results.
UL Testing & Code Compliance
Bodine fluorescent emergency ballasts, emergency LED drivers, emergency lighting inverters and other products are tested by Underwriters Laboratories in accordance with the standards set forth in UL924, "Emergency Lighting and Power Equipment."

Special conditions may apply to certain facilities. See National Electrical Code® (NFPA® 70®), Life Safety Code® (NFPA® 101®) and local codes for complete details.
