Luminaire Characterization – Understanding LED tests, IES LM-79, LM-80, and TM-21

 

Artificial lighting is being used more and more in the world, however it’s usage is quite heterogenous. Electric lighting consumes about 19% of the world total electricity use. Every change in technologies, in customers’ consumption behaviour, or their lifestyle, influences global energy consumption and, indirectly, environment. People stay in indoor environment most of the day. Characteristics of indoor environment lighting are much different than natural outdoor environment. On the other hand, people do not stop activities after sunset. Therefore artificial lighting has impact on their well-being. The needed artificial light has to be provided in an energy efficient and environmentally conscious way. It is important to search for technological solutions which meet human needs with the lowest impact on the environment during operation.

Nowadays technology is rapidly evolving and General and Horticultural Lighting is obviously keeping up. Economic reports about General and Horticultural Lighting show this evolution more clear than ever. LED lighting and its wide range of applications have never been so popular. Still, like every product, it is very important to know how to distinguish what is good and what is not.

In order for this to be possible, Luminaire Characterization is fundamental: knowing the exact specifications of a luminaire is a process that is commonly misunderstood. Taking this into account, we want to provide you with three useful links about the worldwide standards that are used to build a proper report on the characterization of a LED lighting fixture.
