What’s Beam Angle for LED Lighting Fixtures?

The beam angle is something that needs to be taken care of in selecting the appropriate LED lighting for space. The definition of beam angle is different for organizations in different regions, which makes it is more confusing. It is because that it is usually not easy to accurately determine the boundary of the light beam, so make a regulation artificially, specifying an edge, the light outside the edge has been weakened to be negligible or useless. There are international standards for this, but different regions are not uniform. The International Commission on illumination (CIE Europe) stipulates that the angle formed by the two sides at the intensity of 50% of the normal intensity is the beam angle. The Illuminating Engineering Society of North America (IES) stipulates that the angle formed by the light intensity at 10% of the normal light intensity and the two sides is the beam angle.

The beam angle indicates the spread of light from the light source. Narrow beams provide centralized lighting and are suitable for accent lighting. Wide beams give a more general and softer light. Knowing how to use beam angles correctly can significantly improve the lighting effects in a room. Choosing the right beam angle of LED lights is very important for any lighting project. It can also be referred to as a beam spread. Choosing the right type of beam angle can give your building the right type of ambience and visibility.

When choosing the beam angle of LED lights, the basic consideration is to make sure that the space you want to lit can be illuminated. In fact, for any lighting purpose there are some factors that we need to consider, that includes the building type, numbers of lighting fixtures, the height of the ceiling, type of lighting fixtures, and the performance you want to get, etc.
