How to Integrate Emergency Lighting with Control Systems
Uniformity must not exceed 40:1. Light levels along the path of egress are permitted to degrade by 40% over 90 minutes, meaning average light level may drop to as low as 0.6 fc; this allows use of batteries in emergency drivers/ballasts whose voltage will typically degrade over 90 minutes. Though consistent power is not required, some ...
