How do I choose the right beam angle?


What is a beam angle?


The beam angle of a lamp is the angle at which the light is distributed or emitted. The light beam creates a surface where the light of a light sources actually shines. A beam angle is created by a reflector. The smaller the angles in degree (D), the narrower the beam. This can be seen in the image below.

The beam angle is expressed in degrees, indicated by the sign '°' or 'D'. The most common beam angles are 24°, 36° and 40°. The right choice in the beam angle depends on the purpose you have with the light.


Beam angle 10°

The small beam angle. Commonly used when you want to ‘highlight’ something, putting it right in the ‘spotlight’ like art.

Beam angle 24° - 40°

The medium beam angle gives you a wide light. This one is the most commonly used and most of the time placed in places like retail, restaurants and in houses.

Beam angle >60°
