Test Methods

1. Photometric and Electrical measurements – Light Distribution Method:

Photometric parameters were measured using the goniophotometer and software. The ambient temperature

shall be maintained at 25° C ± 1° C, measured at a point not more than 1 m from the sample and at the same

height as the sample. The sample was operated at 120 Volts AC, 60Hz. It was stabilized before

measurement was made. Luminous flux, luminaire efficacy, zonal lumen were calculated from the software

taken at 1° vertical intervals and 22.5° horizontal intervals.

2. Photometric and Electrical Measurements – Integrating Sphere Method:

Photometric parameters were measured using an integrating sphere, a spectroradiometer and software. The

ambient temperature condition inside the sphere was maintained at 25º C ± 1º C. The sample measurements

were made using a spectroradiometer connected by a fiber optic cable and detector through the detector port

of the integrating sphere. The sample was operated at 120 Volts AC, 60Hz. It was stabilized before

measurement was made. Chromaticity coordinates, correlated color temperature and color rendering index

were calculated from the spectral radiant flux measurements taken at least 5 nm intervals over the range of

380 to 780 nm.
