DALI

Maintained emergency lighting remains illuminated during normal operation and during a power failure. Non-maintained lighting only switches on when the normal power supply fails.

Australian commercial emergency-lighting systems are generally inspected and discharge-tested every six months, with records maintained. The exact requirements for the building should be confirmed with the responsible contractor or building manager.

DALI is a digital lighting-control system that allows compatible fittings and drivers to be individually addressed, grouped, dimmed and monitored through a control network.

Panel lights provide broad, even illumination and are commonly used in offices. Battens are linear fittings used in work areas, garages and corridors, while highbays are designed for warehouses and spaces with high ceilings.

The design should consider the required lux level, floor area, mounting height, fitting distribution and surface reflectance. A lighting calculation is recommended for workplaces and larger commercial projects.
