This standard is intended to provide a simple, uniform method for identifying the type and wattage rating of a high-intensity-discharge or low-pressure-sodium lamp installed in a luminaire.
This standard covers dimensional, maintenance, and light distribution features that will permit interchange of post top-mounted luminaires whose center of mass is approximately over the mounting tenon.
