Product Description

Approved American National StandardLearn the procedures to be followed and the precautions to be observed in obtaining uniform and reproducible measurements during life testing of high intensity discharge lamps under standard conditions. This method also applies to other technologies within the metal halide family including ceramic metal halide and pulse start metal halide lamps, and 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.
