Full Description

This document describes the procedures to be followed and precautions to be observed in performing reproducible measurements of total flux of lamps and luminaires using integrating sphere measurement systems. Two types of integrating sphere systems are presented, one employing a V(λ)-corrected photometer head, and another employing a spectroradiometer as the detector. In addition to the specifics of the two measurement systems, the common qualities and measurement techniques are discussed along with calibration and uncertainty analysis considerations. See more
