A light bulb moment

LED lighting increases business energy efficiency

Energy efficient lighting is a quick way for businesses to make energy savings and lower their carbon footprint.

LED (or light-emitting diode) light bulbs are said to last for up to 100,000 hours, compared with the 1,000 hours of traditional incandescent light-bulbs and compact fluorescent lamps’ (CFLs) 15,000 hours.

Using up to 90% less energy than incandescent bulbs, it’s no surprise that Europe is the second fastest growing market after Asia to adopt LED technology.

This means that there is a real opportunity for businesses to make energy savings and reduce costs through smart lighting applications.

Benefits of an LED retrofit

Although there is an initial higher cost in purchasing the new technology, the increasing popularity of LED lamps is boosting the adoption of lighting controls in the UK.

Benefits of LED fixtures include:

• Energy efficient: Turning off or dimming the lights when it’s bright saves electricity, and cuts carbon emissions and costs. This doesn’t affect their lifespan, as LED bulbs are known for longevity – they can last up to 32 years.

• Multi-faceted: Photosensors create a foundation on which you can install more efficient commercial lighting and produce useful data about temperature, occupancy and their surroundings.

• Versatile: Networks can help with security applications, for example by identifying when someone has entered the room. They can also aid simple admin functions, such as monitoring which department uses certain areas and resources.

• Practical: A LED lighting retrofit on a street could support a revenue generating project such as smart parking. Operated remotely, the network could spot free spaces and send the information to a mobile app in real time. Another practical application would be to use LEDs in external areas such as car parks to increase the sense of security for employees and members of the public.

• Environment: Unlike fluorescent tubes, LED lights are recyclable, and provide significant energy savings due to their long life expectancy. LEDs are claimed to last for 25-30 years, dependent on use. Work out how much you could save by clicking here.


LEDs are resilient, flexible and don’t contain toxic chemicals. They use less energy than standard light sources and yet, despite previous criticisms that the light from LED bulbs can be dim and cold looking, they now have a high lumen output.

Of course, any business considering a shift to LEDs has to assess the long-term economics of a retrofit, including the energy saving benefits that will be made. While the price of the LED lighting solution may seem high compared to standard lighting, as the predominant technology in lighting, it does pay for itself many times over during its lifetime.
