Description / Abstract:
This standard covers dimensional, maintenance, and light distribution features that permit the interchange of enclosed pendant-mounted luminaires whose center mass is directly below the mounting bracket. Luminaires of similar size, shape, and weight meeting the requirements of this standard may be used interchangeably within a system with the assurance that:
a) They will fit the mounting pendant
b) Pole strength requirements will not change
c) Light distribution will be similar
d) Similar maintenance procedures can be used
