Description

This Approved Method explains a particular technique for total luminous flux measurement of all types of lamps using integrating spheres.

Total luminous flux is the spatially integrated, photopically weighted, total light output from a lamp. Total luminous flux is an important parameter for non-directional, general lighting products. For directional lamps such as reflector lamps, intensity and beam angle are important parameters. The lamp total luminous flux divided by the lamp electrical power is the luminous efficacy (lm/W) of a lamp. This approved method describes a technique for measuring the total luminous flux of lamps using an integrating-sphere photometer employing V(λ)-corrected photometer head. The approved method is based onthe comparison of the total luminous flux of a test lamp to the total luminous flux of a standard lamp in an integrating sphere photometer.
