This document describes the procedures to be followed and the precautions to be observed in obtaining uniform and reproducible measurements of the electrical and photometric characteristics of general service incandescent filament lamps under standard conditions. The photometric information usually required is total luminous flux (lumens), luminous intensity (candelas) in one or more directions, and chromaticity. The electrical characteristics usually measured are lamp current, lamp voltage, and lamp power. Incandescent filament lamps are usually measured on direct current (DC), and the power can be calculated from voltage and current.
LISUN following instruments fully meet ANSI/IES LM-45 Electrical and Photometric Measurements of General Service Incandescent Filament Lamps:
