IS 16105: 2012 standard covers the method of measurement of lumen maintenance of LED packages, arrays and modules only.
This test method is primarily intended to permit reliable comparison of test results among laboratories by establishing uniform test methods. It addresses the measurement of lumen maintenance testing for LED light sources designed and certified to meet lighting
industry standards.
Performance of the light sources covered in this standard in a particular application may be different.
The method described in this standard does not provide guidance or make any recommendation regarding predictive estimations or extrapolation for lumen maintenance beyond the limits of the lumen maintenance determined from actual measurements.
The method described in this standard covers the measurement of lumen maintenance of inorganic LED based packages, arrays and modules. It does not attempt to induce any failure modes other than the maintenance of lumen output.
IS 16105: 2012 standard does not specify any failure modes other than the maintenance of lumen output.
NOTE — For information on the photometry of the LED light source (see IS 16106: 2012 ‘Method of electrical and photometric measurements of solid-state lighting (LED) products’).
