Emergency and exit lighting in Australia must comply with the National Construction Code (NCC) and the primary standard AS/NZS 2293. 
Light levels: Escape paths require a minimum of 0.2 lux on the centreline, an average minimum of 0.5 lux across the path, and at least 1 lux on stairwell steps. 
Uniformity: The ratio from the brightest spot to the darkest spot on an escape path cannot exceed 40:1. 
Power activation: Emergency lights must reach 10% output within 1 second of a power failure, 80% within 15 seconds, and full output within 60 seconds. 
Battery duration: Backup batteries must keep emergency lights and exit signs running for at least 90 minutes. 
Sign placement: Exit signs must be clearly visible, illuminated constantly while the building is occupied, and mounted between 2.0 m and 2.7 m above the floor. 
Testing and Maintenance (AS/NZS 2293.2)
Six-monthly tests: Qualified technicians must perform a 90-minute monthly/six-monthly discharge test to verify battery and lamp function.
Annual checks: Comprehensive inspections ensure systems continue to meet operational and regulatory compliance.
