Safety is our priority

Emergency lighting is a necessary and important requirement for the safety of and where required, the evacuation of occupants from buildings subject to power failures, or situations relating to causes that may endanger such occupants. General emergency lighting tends to be based on 3 hour battery back-up and is provided either as integral to the main luminaire or as a dedicated remote emergency unit. Morgan Hope offers a range of products to cover most emergency LED lighting needs from general escape route illumination to exit legend signage, all of which are outlined within this section.

With regards to our Integrated Emergency Back-up Systems, integral to the luminaires, we are currently going through a process of upgrading, over the coming months, our existing battery options from NiCd batteries to Lithium technology with LiFePO4. There are various reasons to adopt this newer technology but the three main benefits are:

Lower parasitic load (power consumption) – NiCd batteries require constant trickle charging to maintain their charge. This equates to a power consumption of circa 5W, whereas the self-discharge of the LiFePO4 batteries is minimal at circa 5% per month, resulting in initial charge at commissioning stage and only tops up as and when required, as opposed to constant trickle charge. This reduces power consumption to circa 1.2W, which when extended throughout multiples of luminaires within a building, could make a significant energy cost reduction.

Longer Life – in accelerated testing LiFePO4 batteries still last 3-hours after a 12 year simulated lifespan and as such the envisaged life expectancy should be between 4 to 8 years dependant on application and operational usage, with 8 years not being unrealistic.

Improved environmental impact – Cadmium used in NiCd batteries is highly toxic and the manufacturing process is detrimental to the environment. Globally, governments are attempting to ban NiCd batteries, but historically there have been no suitable alternatives. NiMH batteries were thought to be the next step, but they are simply not reliable enough. The introduction of LiFePO4 batteries provides a solution to overcome the shortcomings of using NiCd batteries.

Addressable Emergency Lighting Systems – The Morgan Hope Addressable Emergency Lighting Systems are designed to operate with various protocols, enabling upgrades of the emergency lighting that will interface with existing addressable systems. Morgan Hope will survey, review and advise on compatibility with existing on-site operations.

Emergency Lighting Integral to Luminaires – The Morgan Hope range of Luminaires are mostly suited to the option of integral emergency battery back-up. The integral emergency systems are all designed to offer 3 hour emergency lighting support based on either standard or self-test.
