The most significant changes impacting the emergency lighting market are the introduction of wireless centralised emergency testing and lithium batteries, both of which reduce the ongoing testing and maintenance costs of emergency lighting installations. Despite the benefits both technologies bring, the rapid adoption of lithium batteries in the lighting industry has resulted in a wide range of products on the market of varying quality and design some of which lack safety features which will likely be mandated for in the future. In recent years lithium batteries have made headlines in industries such as aviation and mobile phones where catastrophic battery failures have resulted in substantial risk to life. Despite this the lighting industry has adopted lithium technology very rapidly with very little oversight and with standards that have as yet to adapt. Whilst many companies use only the highest quality emergency components with all safety considerations taken into account, including ourselves, many products on the market do not include the same diligence. At present all lithium chemistries are permitted, from the more volatile Lithium Ion through to the highly stable Lithium Iron Phosphate and thermal protection which can disconnect charging circuits before thermal runway occurs have not as yet been mandated for. The market places the onus on the customer to understand the potential pitfalls and to specify the correct product, this may not always be the case especially where budgetary pressures push them to the lower cost end of the market. It is crucial both that legislation is updated to create a level playing field with safety at the forefront and that customer awareness is raised to move demand towards luminaires with adequate safety features. A catastrophic battery failure in a single mobile phone which can be quickly discarded is dangerous but is far more so when you consider the quantity and inaccessibility of emergency batteries in our workplaces, schools and hospitals.
