The main test of ies lm-79 is photoelectric performance test. Because some test items need to be completed with the help of distributed photometer, ordinary manufacturers are not able to make a complete report. This test is generally aimed at manufacturers of the whole lamp. The main test items are as follows:
Total light flux
luminous efficiency
Light intensity distribution
Relevant color temperature (CCT)
Color rendering index (CRI)
Chromaticity coordinates (or chromaticity coordinates)
Input AC (or DC) voltage
Input AC (or DC) current
Input power (DC or AC)
Input voltage frequency power factor
