Technical focus Improving Efficiency


Modern lighting can make a major contribution to energy saving and hence carbon reduction targets. David Jones looks at the trend towards more efficient lighting.


Major technology developments in the last few years have resulted in significant improvements in energy use for lighting. Reductions of over 40% can be regularly achieved when compared to existing lighting. The prime innovation leading to these improvements has been the production of light fittings with very high efficiencies. The drive electronics in modern fittings run fluorescent tubes very much more efficiently than in the past. This produces higher light output per watt of power consumed, resulting in lower energy use, and helping reduce an organisation’s costs and carbon footprint. These more efficient fittings are available across the entire range of fluorescent lights as well as for standard ones such as T5.


Other innovations such as intelligent space controllers, which will dim the lights when nobody is in a room, add to the savings. Some existing light fittings can be upgraded with a retrofit option resulting in an even


40


lower change over cost, resulting in a shorter payback period. LED lighting has progressed enormously and is now well worth considering for many applications such as corridor downlights and emergency applications. They are still not appropriate for many working applications since when using them at high light output the white can be very harsh, resulting in an uncomfortable working environment for the users and even eyestrain. The colour temperature can be adjusted to be “human-friendly” but this results in reduced output, hence the need for more fittings. With their much higher capital costs, this can result in unreasonably long payback periods. These innovations must be used appropriately so that light levels are correct – both brightness and colour temperature, along with maintaining the right levels of safety must be right for the user. Different solutions are appropriate for different


applications. The key to finding the right lighting for the application is to consult with a specialist lighting manufacturer that is keeping at the forefront of technology. Our many years of experience providing lighting solutions for the public sector here at Flourel means we are exceptionally well qualified to provide expert advice on getting the right result for each individual location. We have been a leading supplier of innovative lighting systems for over 50 years, and we are the supplier and adviser of choice for many local authorities, education, health, office and retail organisations.
