Why should you use asymmetrical lights?

When buying a new floodlight you may stumble upon the type of light beam emitted: symmetrical or asymmetrical. This technical feature plays a key role in creating the optimum lighting effect in application areas such as stadiums, theaters, sport arenas or streets. In this blog you will be able to learn about the advantages of asymmetrical beams in order to maximise the light output and unlock the full potential of light.


What is the difference between asymmetrical and symmetrical light distribution?


Symmetrical light sources distribute light evenly in all directions. This type of light beam is recommended for both general lighting of large spaces and accent lighting for visual tasks. On the other hand, asymmetrical lighting is ideal for concentrating the light beam in one direction. Therefore, it can be an efficient solution for offices, as it does not produce direct glare that can cause eyestrain with protracted exposure.


Where to use asymmetrical light?


These light sources can be used in a wide range of application areas, both indoors and outdoors such as gyms, theaters but also stadiums, parkings and streets. While symmetrical lights produce both direct and indirect glare, asymmetrical fixtures are designed to lower indirect glare and reduce sharp shadows. When installed in workplaces, it facilitates the transition from dark to light spaces, allowing eyes to work under a comfortable light. Therefore, when asymmetrical light is used in stadiums, for instance, the overall lighting will be friendly to not only the players but also to the audience.

What are the advantages of an asymmetrical light beam?


Light fixtures with an asymmetric light beam have integrated advanced optics that allow to direct the light beam to a selected area. The most common fixtures are known as “reflectors” or “parabolic” as they make use of a mirrored surface able to reflect and concentrate the light beam. This means that with asymmetric fixtures it is possible to achieve the same visibility of traditional fixtures with significantly lower energy costs. The light emission is not wasted on areas where it is not needed. By doing so, this light technology has reduced the number of light sources needed for the general lighting of a space.
