Three Key Specifications Of An LED Lamp

267 0

The LED technology is developing in recent years at a dizzying pace in lighting. The direct consequence is the simultaneous commercialization in the market of products of very diverse quality.

How can we distinguish each other? The answer is found in the labeling and the specifications sheet for each product. It contains technical data that refer to the following aspects.

Luminous Flux Or Emitted Lumens (Lm)

This feature is a good indicator of the quality of an LED as it refers to the amount of light it can produce regardless of its beam opening. Offering a large flow of light with low power (lm / W) has a direct relationship with the quality. However, it should not be confused with luxes (lux), which are the amount of light that affects a particular point. It depends on the flow in lumens and the opening of the light beam. We must bear in mind that a high “lux” value can also be achieved with an emitter of few lm if the beam opening is small. In those cases, despite having a high lux value, the lamp will illuminate a reduced surface. Visit to get wonderful designs.

IRC (CRI, Ra)

It is the Chromatic Performance Index and refers to the ability of a light source to faithfully reproduce the colors we would see under the midday sunlight on a clear day. It generates visual comfort and real and pleasant environments. An IRC must be greater than 80 to obtain quality lighting.

Energy Classification Of The Luminaire

At the European Economic Community level, an energy efficiency label was developed that classifies LED luminaires according to their real energy efficiency. Thus, depending on the lumens generated and the actual power consumed (that is, the actual efficiency), as well as the opening of the light beam (directional or non-directional), different classifications are obtained. In LED, this classification can be:

  • A ++ (very efficient)
  • A +
  • A (efficient)

While for non-LED luminaires, the energy rating that can be obtained is B, C, D, or E, the latter being the least efficient of all.
