With lighting accounting for 20 per cent of all the energy consumption in the UK, you should know that along with that comes a big chunk of energy bills. Lighting can take up to around 40% of a building’s electricity, meaning that if you were to switch to a more efficient lighting it could dramatically cut the costs.
LED’s (Light-emitting-diode) lights are valued for their strong white glow and won their inventors the 2014 Nobel Prize for physics³. Being ‘instant on’ lights, they don’t need time to warm up before they are on at full strength and consuming a considerably less amount of electricity.
LED’s work differently to ordinary incandescent bulbs, which emit light as a current is passed through the metal within them. LED’s on the other hand pass electrons through a semiconductor and because of this, they have no filament to wear out meaning they don’t get as hot.
LED’s are very versatile and can be used in a range of different ways, from clothing, digital signage to mood lighting in planes and homes and they can be integrated easily. LEDs have been widely adopted and used in medical applications (thanks to their reliable, bright white light) and have already started to replace the tubes that light up LCD HDTVs to make the televisions dramatically thinner.
The benefits of LED lighting are becoming more known and appreciated by customers as they replace their standard filament, halogen and fluorescent strip lights. LED lighting can be more attractive, energy efficient, cost-effective and durable than the pre-existing methods. It isn’t difficult for a new lighting solution to make a big difference in the bottom line relatively quickly. In terms of energy efficiency, a standard 50W halogen lamp uses only 10% of the electricity it consumes for producing its light. In a commercial building filled with halogen bulbs, swapping out these bright but very inefficient lights could see business reduce their lighting bills by a huge 90%.
Although LED prices are falling rapidly, they can be quite expensive initially compared to fluorescent tubes. However, they do have an operating lifespan of around 70,000 hours which is 10 times longer than a standard lamp, according to Philips LUMEC.
