The beam angle of a light fixture is the angle between the two rays of light that are emitted at the outer edges of the beam. It is essentially the width of the beam of light emitted by the fixture, measured in degrees. A narrow beam angle would be around 15-20 degrees, while a wide beam angle would be about 60 degrees or more. The beam angle is an important consideration when selecting a light fixture as it impacts the distribution and concentration of light in a particular area.
