Keeping it Efficient


Lighting is one of the largest consumers of energy, and it is great that the industry is being proactive about sustainability. LED fixtures are highly energy efficient and have provided the industry with a wonderful product to help reduce the environmental impact of projects. However, as with any technology, education is essential to ensure the correct implementation of products to create energy efficient solutions. There are a number of external factors to understand in order to make the most of new technology and ensure its energy efficient use. For use in projects such as offices, for example, lighting is a huge drain on energy use, and efficient use of LEDs can make a real difference to the environmental and financial impact of a lighting scheme. Steve Hemsworth, Head of Sector Lighting at MITIE believes that lighting is a perfect start for offices tackling energy efficiency; “Lighting can be responsible for around 30% to 40% of an office building’s electricity costs, so it’s an obvious starting point for any organisation looking to

The term ‘energy efficiency’ is something that we hear fairly frequently at A1 Lighting, but just how easy is it to create a truly efficient project? We discuss the subject with some of the biggest names in the industry.

implement an energy efficiency programme.” However, LED implementation has to be thoroughly considered to ensure that investment in the technology will pay off.

“Simply switching to LEDs seems obvious, but LEDs aren’t just a fit-and- forget solution, particularly if they are being retro-fitted to an existing workspace,” explains Hemsworth. “The installation needs to be correctly designed by

someone who fully understands the virtues and weaknesses of LEDs and how to deploy them to best effect. In some instances it may be that LEDs don’t actually represent the most appropriate solution

and more conventional solutions may work better.” It is easy to think of LEDs as the be all and end all of efficient lighting, but it is important to thoroughly research the products being used in any one project, as performance can vary. When using LEDs, efficient control is an important aspect of overall performance, and Harvard is dedicated to the

development of high quality LED control solutions. The company showed an interest in LEDs early on, and has been able to develop a range of drivers that are truly suitable for the technology. The award winning CoolLED drivers have a cool operation, and are designed with efficiency in mind. The products have been installed across a number of applications, including retail outlets such as BMW, Nike and Jaegar, and industrial facilities, including their own factory. The CL Standard class II driver is power factor corrected, with fully isolated SELV output. The driver delivers up to 33W of power and has dimming capabilities meaning that lights can be dimmed when not needed at full power. If installers dim the light at night in window displays, for example, this results in a more eco-friendly installation. The use of drivers can also ensure excellent light uniformity is achieved. Peter van der Kolk, Business Development

Director at Helvar, is also extremely passionate about the use of correct drivers for LED applications. Using the incorrect control gear for a particular LED can affect performance, as van der Kolk explains; “When control gear is not taken into account at an early stage, then it could lead to incompatibility, or compromised quality or functionality.” It is important, therefore, to
