This approved method is intended to promote uniform test results as obtained under controlled laboratory conditions in measuring the luminous flux and intensity of high-intensity discharge and incandescent indoor-type luminaires. All mercury, high-pressure sodium (HPS), and metal halide lamps are classified as High-Intensity Discharge (HID) lamps, and their photometry, when installed in indoor-type luminaires, is covered by this method. Also covered are similar luminaire types employing incandescent lamps, including tungsten-halogen lamps.
