What is a beam angle?
Definition
Lighting products sometimes talk about beam angle, but what is it? A beam angle, also called the degree beam, indicates the angle of the beam that a light emits. This beam angle is expressed in degrees (°); the smaller the number of degrees, the narrower the beam is. The larger the number of degrees, the wider the degree beam will be.
Different types of beam angles
The most common beam angles can be divided into categories, namely: 10°, 24° to 36° and 60° or more. The 10° beam angles are very suitable for illuminating a certain object. This allows you to lighten a particular object precisely. The 24° to 36° angle are the medium radiation angles. This category already lightens a larger area than the 10°. As the beam angle is larger, fewer spots are needed to light a total space. This light is more often used, for example, in receptions and domestic rooms to create a cosy atmosphere. Finally, there is the 60° angle. This is a large beam angle that is more often used within offices, warehouses and general areas. This is because the angle is so large that it can illuminate as large an area as possible evenly.
