How far apart should emergency lights be?

Australian Standard AS/NZS 2293.1:2018 specifies a minimum light level of 0.2 lux with a minimum of 0.5 lux at floor level under emergency lighting conditions. For stairwells, this should be a minimum of 1 lux. This emergency light level should be maintained for 90 minutes upon power supply failure to standard lighting. The level of light on the floor or the tread of a step depends upon the lumen output & light distribution of the fitting and the mounting height of the fitting above floor level.

How are emergency light fittings assigned classifications?

For example, asymmetrical spitfire emergency light can have a single emergency classification of D50, whereas a batten with asymmetric distribution can double C0-180: D80 & C90-270: D40.

The Alphabetical classifications can vary from Class A to Class E & numeric values can range from 1 to 800. Class D Classification is most commonly used while designing spaces for emergency layouts. The higher the numeric value after the alphabet, the higher the luminous intensity of the fitting.

Labs accredited by NATA or equivalent bodies for the AS/NZS 2293.3 standard should only do this testing.
