IES LM-51 – Approved Method: Electrical and Photometric Measurement of High Intensity Discharge Lamps
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 high intensity discharge (HID) lamps under standard conditions in alternating current (AC) circuits at 60 Hz. The HID lamps covered by this document include the lamp groups commonly known as mercury vapor, metal halide, and high pressure sodium used in general lighting applications. The photometric information usually required is total luminous flux (lumens) and/or luminous intensity (candelas) in one or more directions, and color. The electrical characteristics usually measured are line voltage, lamp voltage, lamp current, and lamp power.
