Energy Lighting Tips

There are a few things to think about to achieve a sustainable lighting in retail.

1. Lighting Design

When planning a lighting installation the placement of the light sources is essential.  If you place and aim the luminaries in an optimal way you will not have the need for as many luminaries as if you placed them randomly. Planning your lighting demands specialised knowledge.

At Fagerhult we have expertise within this area and know what is required to create a solution that is not only energy efficient but is also commercial and functional. This knowledge also contributes another dimension – atmosphere.

An investment in a new lighting installation is easy to recover, particularly if you choose to install a control system with motion and daylight sensors. Your new lighting system will usually pay for itself fast because of your reduced energy consumption.

Life Cycle Cost Calculation gives it to you in black and white: how much you will benefit from replacing an outdated installation. Fagerhult's own Life Cycle Cost Calculator (LCC) demonstrates the links between investment cost, choice of lighting solution, energy consumption and environmental impact.

In addition, you can find out how much CO2 emissions the installation will generate throughout its entire life. It also calculates the total installation cost and payback time, taking into account interest rates and inflation.

2. Choice of technology


LED technology has really broken through in recent years, and to a large extent is beginning to replace fluorescent tubes and metal halide. The technology is highly energy-efficient and very durable, provided that the LEDs are used in luminaires specifically developed for LEDs.

LED modules do not either contain any mercury, which simplifies their handling at the point of recycling and reduces the risk of emissions to the environment. Investing in LEDs means that you don't just save money on lower energy consumption over a long period of time – you are also contributing to reducing waste in our throwaway society.

Reflectors and anti-glare protectors

The reflector used in a luminaire has a very important function: it's what maximises efficiency and orients the light in the right direction. The use of anti-glare protectors also helps to steer and screen off the light so that the eye is not dazzled. Often the reflector and anti-glare protector are two separate parts of the luminaire, but in some instances they can be combined into one part.

The choice of materials for reflectors and anti-glare protectors is important for energy efficiency, so we choose them with care. The better the material, the higher the efficiency and the lower the luminaire's environmental impact. 


The quality of electronic drivers and other light source control gear is very important for the energy efficiency of the luminaire. Different types of control gear work best in different types of luminaire – and this is a choice that we make for our customers, of course.

Right at the design and development stage, we ensure that the control gear, light source and luminaire all work together to optimise energy efficiency and length of life.

One of the most important factors is that the control gear's temperature does not get too high when the luminaire is switched on. In the development of our luminaires, we don't just follow the control gear manufacturer’s recommendations: we add an extra safety margin of 5°C. This means in theory that our luminaires have a better service life than specified by the manufacturers of electronic drivers and other light source control gear. And of course we use only electronic high-frequency drivers and control gear from the world's leading suppliers.

3. Controls

The large increase of LED on the lighting market has made it easier to use controls in retail lighting solutions.  There are many ways to control the lighting to save energy, and the right way to do it depends largely on what kind of shop you have. Using sensors that detect movement and daylight are ways to avoid using artificial light when it is not needed. On a sunny day when strong light shines directly on the shop window you have great opportunities to dim down your lighting and take advantage of the natural light while saving energy.

During times when the shop is less busy, you might want to save energy by decreasing some of the lighting. This can be achieved by using sensors that dim the light when there are no customers around, but you can also set different lighting scenes that can be changed easily. The scenes can be controlled by timer or manually. Perhaps you need less lighting before opening or early in the day when the shop does not have many visitors. Another option is to connect the lighting system to a counter at the shop entrance to keep track of how many customers enter and leave the shop. When the number of visitors reaches a peak, the best possible lighting scenes are turned on.

The lighting installation does not need to be on full power all the time if you can control it. If a luminaire is dimmed by 10%, it is hardly detectable to the human eye but will create energy savings of 10 %. An investment in a solution with controls is justified by the large potential for energy savings .

Over 30 % of a shop’s energy cost is for lighting. Lighting control can bring significant energy savings to any application, and iTrack can be controlled in many different ways.

4. Maintenance

Optimised savings on energy consumption is increasingly important to reduce and control future energy demands and directives. It will not be enough buying energy efficient products but also necessary to have a maintenance plan to keep the installation energy efficient over time.

Energy optimised installations with less fixtures demand a solid maintenance plan that contains maintenance of fixtures but also maintaining the commercial impact by aiming the luminaires sufficiently on to the merchandise. A maintenance plan shows that you care about your lighting installation and you get more value out of your investment.
