本文件提供了一种方法，用于在受控实验室条件下测量高强度放电（HID）灯具（包括汞蒸气、高压钠（HPS）和金属卤化物灯）的光通量和强度，以获得统一的测试结果。还包括使用白炽灯的类似灯具类型，包括卤钨灯。

This document provides a methodology for obtaining uniform test results under controlled laboratory conditions in measuring the luminous flux and intensity of luminaires with high intensity discharge (HID) lamps, including mercury vapor, high pressure sodium (HPS), and metal halide lamps. Also covered are similar luminaire types employing incandescent lamps, including tungsten-halogen lamps.
