ANSI/IES LM-47 Life Testing of High Intensity Discharge (HID) Lamps

This document describes the procedures by which HID lamps can be operated under controlled conditions to obtain optimally comparable data on individual lamp life, changes in light output, and other parameters that vary during the life of the lamp. It describes the procedures to be followed and the precautions to be observed in obtaining uniform and reproducible measurements during life testing of HID lamps under standard conditions. It also covers other technologies within the metal halide family, including ceramic metal halide and pulse-start metal halide lamps. It addresses life testing of high intensity discharge lamps operated on auxiliary devices, either external or integrated, designed and certified to meet lamp industry standards and tolerance.
