The beam angle of a bulb is measured because the angle between the 2 instructions opposed to one another the place the luminous depth is 50% of the utmost luminous depth. In easier phrases, the beam angle provides one a way of how huge the beam spreads out when emitted from the bulb and might vary from a slender highlight to a really huge floodlight.
