Third thing need to Consider When Choosing an Intelligent Emergency Luminaire

- Mar 17, 2020-


Even if testing does occur randomly, having even one luminaire on-site which is completely discharged could present a safety risk. Allowing a battery to discharge completely presents a risk of total light loss if an emergency scenario occurs at the end of a discharge cycle; with no charge in the battery, there is no power to the luminaire in emergency mode.


Crucially, if some reserve capacity is retained, and the batteries are only discharged to around a third of their capacity, at worst the luminaire will still be able to provide around one hour of light in emergency mode (depending on the power / % output). Opting for a luminaire which retains reserve capacity during testing is therefore an important consideration.
