1.3 Test Methods
1) Photometric and Light Distribution Measurement – Goniophotometer 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 or rated 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) Chromaticity Measurement – Sphere-Spectroradiometer Method:
Chromaticity 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 or rated Volts AC,
60Hz. It was stabilized before measurement was made. Chromaticity coordinates, correlated color
temperature and color rendering index were calculated from the spectral power distribution taken at 5
nm intervals over the range of 380 to 780 nm.
3) Electrical Measurements:
Electrical parameters were measured using power meters incorporated in goniophotometer or
sphere-spectroradiometer system. The ambient temperature surrounding the sample was maintained at
25º C ± 1º C. The sample was operated at 120 or rated Volts AC, 60Hz. It was stabilized before
measurement was made. Voltage, frequency, current, power, power factor and total harmonic distortion
were measured by and read from the power meter.
