What are LM 79 Test Outcomes?
LM-79 is approved test method for electrical and photometric measurements of Solid State Lighting Products. It describes the procedure in measuring total luminous flux, electrical power, luminous intensity distribution, chromaticity under standard conditions. It covers LED based SSL products with control electronics and heat sink incorporated with AC or DC power supply. This does not include LED chips, LED package or LED module but luminaries (fixtures incorporating light source) as well as integrated LED lamps.
The equipment used in LM-79 is integrated sphere and goniophotometer.
Integrating Sphere Goniophotometer
The test report shall list all significant data for each SSL product tested together with performance data. The outcomes of the LM-79 test are:
- Correction factor applied ( e.g. spectral mismatch, self absorption , intensity distribution etc.)
- Measured total luminous flux( lumen(lm)), input voltage(v), current(a), power(w), Luminous intensity distribution(cd), efficacy(lm/w)
- Color quantities( chromaticity coordinates, CCT, CRI )
- Spectral power distribution
- Bandwidth of spectoradiometer, if spectral distribution and/or color quantities are reported.
- Statement of uncertainties (if required)
- Deviation from standard operating procedures, if any.

- Efficacy (lm/watt)
- Chromaticity
How To do Photometric Testing?
Check Our Photometric Testing Scope
Absolute Photometry Basis
- LM-79 requires complete luminaire testing
- Traditionally, photometric evaluation of lighting products is based on separate tests for lamps and luminaires
- For SSL products, LED lamps typically cannot be separated from their luminaire because of heat effects
Relative vs. Absolute Photometry
Relative testing – Lamps of interest and luminaire are measured separately. Then the actual light distribution and intensity of the complete luminaire of interest is derived by normalization of the test data
Absolute testing – The actual light distribution and intensity of the luminaire of interest is measured directly from the complete luminaire.
For your better understanding, we are going to show you the Photometric Test report of latest LED in the following:
