exposed to flickering lights, it resulted in more than a 50 per cent increase in complaints of eye strains and headaches. Furthermore, research by the occupational safety and Health administration (osHa) suggests that when objects move or rotate rapidly, flickering lights can make them look as if they are moving more slowly than their actual speeds causing dangerous hazards. around 80 per cent of our sensory input at work comes through our eyes. therefore, compromising our vision is not an option when considering energy efficiency measures. Quality leDs exhibit very little to no flickering, even when dimmed, because they are typically powered by constant Dc voltage, unlike incandescent and fluorescent lights. buying clean technology, such as
leDs, on a large scale can be perceived as an expensive investment, yet paybacks can be achieved in two to three years. However, there are solutions available such as no caPeX alternatives, monetary loans and energy performance contracts which permit no upfront costs. savings are instant and measureable through smart metering. additionally, retrofit technology now enables modern leD lamps to be compatible with outdated casings, meaning that significant cost savings can be made by retaining the original fittings but updating them with the latest in lighting technology.

application to leD can significantly help in becoming more sustainable. Quality leDs contain innovative cooling systems which are the fundamental drivers behind the system’s performance and life-span. this is turn means that the lamps are thermally managed, and the need for air conditioning is significantly reduced. moreover, the majority of leD systems operate at a lower wattage (i.e. power consumption) than traditional light sources and when used in conjunction with dimming and controls, can result in a
dramatic reduction of energy usage. in particular, businesses should make full use of daylight controls that maximise the use of natural sunlight. the majority of these controls also include motion sensors, meaning that lights will remain off when a building is empty. this combination of both daylight and motion sensors can save approximately 45 per cent of a building’s energy usage, making it a valuable long-term investment. a study by lighting research and
technology found that when workers were
Despite these benefits, organisations need to remain wary when choosing an leD supplier. inflated performance promises, often from overseas suppliers who sometimes provide cheap, badly made leDs with a lack of instructions on how to properly install and use the products, has resulted in negative experiences for those on the receiving end. as a result, it is absolutely vital that when investing in leD products, businesses buy from a reputable supplier to ensure they receive the best value possible. it is clear that there has to be an immediate and improved awareness in reducing energy spend and businesses need to utilise the efficient technology available to them. leDs are one of today’s most energy-efficient and rapidly-developing lighting technologies. Quality leDs last longer, are more durable, and will play an integral role in shaping not only the look and feel of an area but also the efficiency of the building whilst keeping costs down.
