How are emergency light classifications assigned?

Written by: Surya Bedi | Published: 14-Dec-2016

Australian Standard AS2203.1-2005 requires a minimum light level of 0.2 lux at the floor under emergency lighting conditions.

We outline the emergency luminaire testing & classification process, which takes into account maximum spacings between emergency lights for a range of mounting heights.

Emergency Lighting: Classification

Australian Standard AS2203.1-2005 specifies a minimum light level of 0.2 lux at the floor under emergency lighting conditions. The level of light at floor level will be dependent on the light output of the fitting and the mounting height, measured in metres from the floor.

How are emergency light fittings assigned classifications?

Emergency light fittings are tested and based on performance, are assigned classifications to number of classes (A to E). Fittings with more than a single light source are generally classified according to axes: C0, C90, C180, C270 as the light distribution is not symmetrical.

The published standard for emergency lighting, AS2293.1, includes Tables 5.1 to 5.5, which list the maximum spacing between emergency light fittings per classification, for a range of mounting heights.

The following table is a summary of Tables 5.1-5.5, according to the Chamaeleon light range classifications. There is no change in classification according to light output or number of LEDs per model, other than the wall or ceiling mount.
