Answer
The angular dimension of the cone of light from reflectorized lighting devices encompassing the central part of the beam out to the angle where the intensity is 50% of maximum. The beam angle sometimes called "beam spread" is often an optional item for LED lighting devices. For example: Spectra IV offers narrow and wide beam angles of 26 and 80.
