​Certification IES LM-79


Certification IES LM-79 The main test is the optoelectronic performance test. Because some test items require the use of a distributed photometer to complete, the average manufacturer does not have the ability to do a complete report. This test is generally aimed at the entire lamp manufacturer. The main test items are as follows:

Total luminous flux
Luminous efficiency
Light intensity distribution 
Correlated color temperature (CCT)
Color Rendering Index (CRI) 
Color coordinates (or chromaticity coordinates)
Input AC (or DC) voltage 
Input AC (or DC) current
Input power (DC or AC)
Input voltage frequency
Power factor
