The easiest way to think of beam angle is the angle at which light is emitted. The more complete answer is that beam angle is the full width at half maximum. In other words, since we can’t measure the “edge” of light, but we can measure the intensity of light, we measure the beam angle from where the light is at 50% intensity.
