LM79 test

The main test of IES LM-79 is the photoelectric performance test. Since some test items need to be completed with the help of a distributed photometer, general manufacturers are unable to make a complete report. This test is generally aimed at manufacturers of complete lamps. The main test items are as follows:

total luminous flux

Luminous efficiency

Light intensity distribution

Correlated 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
