In recent years, LED lighting technology has developed significantly and costs have fallen


Illuminating LEDs


Giuliano Digilio, the ECA’s head of Technical Services and Dr Michael Dangoor of Orlight look at the latest developments in LED technology and explain where it all comes from

ver the coming years, in order to reduce CO2 emissions, EU legislation will enforce a gradual


phase-out of the most inefficient lighting products. However, there are huge savings to be made by


making the switch to energy-efficient lighting solutions sooner rather than later. So what lamp types and lighting solutions should electrical contractors be looking at? Well, the buzz in recent years has been all about LED technology. While LEDs are not new in themselves – having been used in emergency lighting, street lighting and retail lighting – big improvements in light output and price reduction are resulting in lighting manufacturers and suppliers all making moves on LED technology for

domestic applications and in general commercial office lighting solutions. LED lighting technology is now able to deliver real energy


savings to your clients from day one, and for some clients will also contribute to their Carbon Reduction Commitment (CRC). Most LED lamps and LED fittings also comply with the requirements of Part L of the Building Regulations (Conservation of Fuel and Power).


Advances Major advances have been made with LED lamps, downlights and, more recently, with modular recessed and industrial fittings. Aside from low energy, there are a number of operational and environmental benefits of using LED technology on your future projects. Their extraordinary long life (50,000 hours plus)


means they need zero maintenance, with no light source replacement, thus reducing whole life cycle costs of projects. In addition, the colour is excellent, they emit neither UV nor IR radiation and contain no mercury. Since the invention of LEDs in the early 1960s, there
