Emergency Lighting

A collection of premium luminaires with quality batteries in the event of an emergency.

Here at ASD Lighting, we are continuously looking for new innovations that will provide you with the best possible luminaire that is fit for purpose and saves on your overall energy usage.

The all new lithium iron emergency lighting collection of luminaires offers a premium fitting with a quality battery in the event of an emergency.

Lithium Emergency Lighting

Lithium Iron Phosphate battery technology offers 4 year warranty. Providing a low parasitic load, huge energy savings per annum and a much longer lifetime when compared to Nickel Cadmium batteries.

Efficient

The following table shows a comparison between the four types of batteries being used for emergency lighting purposes and highlights the benefits of lithium Iron.

Battery Type	VRLA	NiCd	NiMH	Lithium Iron
Parasitic Load	2W	5W	2W	1.2W
Energy Efficiency	60%	75%	70%	95%
Self-Discharge per Month	5%	20%	30%	< 5%

Application

A building with 1,000 emergency light fittings would use the following amount of power each year simply charging each particular type of battery.

VRLA	NiCd	NiMH	Lithium Iron
17,520 kWh	43,800 kWh	17,520 kWh	10,512 kWh

Currently, the average energy price in the UK is 14.71p per kWh, so the cost of simply charging emergency lighting batteries in each case for this example would be as below:

VRLA	NiCd	NiMH	Lithium Iron
£2,577.19 per annum	£6,442.90 per annum	£2,577.19 per annum	£1,546.31 per annum

Over a five-year period, using Lithium Iron batteries rather than NiCd on this example scheme, would save the client £24,482.95 in energy bills alone.

Reliable

The following chart shows a NiCd battery coming to the end of its life after four to five years, whereas the Lithium Iron cells are still going strong.

Low parasitic load (1.2W).
Very low self-discharge (5% per month).
Very long operational life.
No memory effect or thermal runaway.
4 Year guarantee.

Can be recycled.
No toxic materials used in manufacture.
Designed, developed & manufactured in the UK.
BS EN 60598.

Operational Life of Lithium Iron Batteries Against Traditional Nickel Cadmium

One of the tests carried out on emergency lighting batteries in order to register for ICEL1010 certification uses a method of accelerated testing in order to mimic a four year life over a one year period. This is achieved by heating and cooling the battery to certain levels under charge and discharge, taking capacity measurements at set points.
