LM-79 Test Report (Luminaire Photometric Test Report)
The LM-79 test is conducted to gather data relating to the luminaires:
• Total Luminous Flux
• Luminous Intensity Distribution
• Electrical Power
• Luminous Efficacy (calculation)
• Color Characteristics Chromaticity
• CCT
• CRI
The LM79 test requires the complete luminaire to be tested, this also known as
Absolute Photometry. Unlike traditional ‘Relative’ photometry, solid state lighting
products cannot have their LED’s separated from the luminaire due to heat effects.
