Cold Weather Testing

Most UK emergency lights are not designed to withstand prolonged periods of extreme cold temperatures. An external emergency light could be installed where no sunlight is ever received. Receiving direct sunlight benefits the emergency light with the suns warmth during the day. The emergency light will generate some of it’s own heat from the control gear and the light itself, but not enough to combat many days and nights of sub zero temperatures.

The component inside that will suffer the most is the battery. Batteries are designed to withstand short periods of freezing temperatures and still provide three hours of emergency light. This is one of the reasons that the batteries need changing every 3 to 4 years. To ensure that the 3 hour duration is achieved. But when it has been exposed to low temperatures over and over again, that degradation is increased and the battery may need to be replaced sooner.

Even though a full duration test may not be scheduled for a few months, it is a good idea to do a test early to see if the batteries can still provide you with 3 hours emergency lighting.

If you do need new batteries please visit the accessories section or call us to discuss your needs.

Central Battery Emergency Lights

What are central battery emergency lights

As the name implies a central battery emergency light is one where it’s power comes from one source somewhere within your building. These central battery emergency lights do not have a battery inside them and rely on the central battery to supply the whole system in the event of a power cut. Inside the light will be a pcb and LED light strip with all the control of when to switch on controlled by the central system.

Test your Emergency Lighting after the hot weather

Inside a self contained emergency light the temperature can rise rapidly with been exposed to full sun all day. The luminaire will generate some of it’s own heat from the control gear and the light itself and if it is in a IP rated housing that heat has no where to go.

The component inside that will suffer the most is the battery, they are designed to withstand short periods of heat and still provide three hours of emergency lighting. This is one of the reasons that the batteries need changing every 3 to 4 years to ensure that the 3 hour duration is achieved. But when it has been exposed to high temperatures over and over again, that degradation is increased and the battery may need to be replaced sooner.City skyline with sun
