Term:
Radiaton Angle
The radiation angle is the vertex angle of the cone of light emitted at the exit face of a lamp or reflector lamp. It is defined through the way the reflector light is designed.
For uniform light distribution (general lighting, spot lighting), a wide angle light is used with radiation angles up to 80 degrees (= flood). For accent lighting, a narrow beam light with small radiation angles up to 24 degrees (= spot) is first choice.
