9 6, Test Method The method according to IESNA LM following chapter 4.0 SENSONING OF SSL PRODUCTS Report Number: BSR For the purpose of rating new SSL products, SSL products shall be tested with no seasoning. 5.0 STABLISIZATION OF SSL PRODUCT Before measurements are taken, the SSL product under test shall be operated long enough to reach stabilization and temperature equilibrium. The time required for stabilization depends on the type of SSL products under test. The stabilization time typically ranges from 30 min. (small integrated LED lamps) to 2 or more hours for (large SSL luminaires). The SSL product during stabilization shall be operated in the ambient temperature as specified in section 2.1. It can be judged that stability is reached when the variation (maximum-minimum) of at least 3 readings of the light output and electrical power over a period of 30 min., taken 15 min. apart, is less than 0.5%. The stabilization time used for each SSL product shall be reported. 9.0 TEST METHODS FOR TOTAL LUNIMOUS FLUX MEASUREMENT The total luminous flux (lumen) of SSL products shall be measured with an integrating sphere system or a goniophotometer. Spectral radiant flux measurements are made using High-precision spectral radiometer attached to the detector port of the integrating sphere. Luminous flux, chromaticity coordinates, correlated color temperature, u, v and color rendering index for each lamp are calculated from the spectral radiant flux measurements taken at 1nm/ 5 nm intervals over the range 380 to 780 nm. Lamp efficacy (lumens per watts) for each lamp model is computed based on this luminous flux result. Sphere size of 1.5m/2 m is used for compact lamps (size of typical incandescent and compact fluorescent lamps) or larger for larger lamps (size of 4-foot linear fluorescent lamps and HID lamps). 2 m sphere is used for measurement of light sources of 500 W or larger. The total uncertainty of the light output measurements is estimated, at the 95% confidence level, k= LUMINOUS INTENSITY DISTRIBUTION Goniophotometers used to measure luminous intensity distribution. For measurement of luminous intensity distribution, a sufficient photometric distance should be used generally, more than five times of the largest dimension of the test SSL product having broad angular distributions. Electronic data of measured luminous intensity distributions shall be prepared in the IES file format for absolute photometry specified in IES LM IES file is an electronic data format that can be used by specifiers and designers to reliably predict illuminance levels in design applications LUMINOUS EFFICACY The luminous efficacy (lm/w) of the SSl product, ην, is given as the quotion of measured total luminous flux φ TEST (lumen) and the measured electrical input power P TEST (watt) of the SSL product under test as ην =φ TEST (lumen) / P TEST (watt) [lm/w] Pages: 9 of 15

10 12.0 TEST METHODS FOR COLOR CHARACTERISTICS OF SSL PRODUCTS The color characteristics of SSL products include chromaticity coordinates, correlated color temperature, and color rendering index. Using High-precision spectral radiometer system to measure luminous flux, chromaticity coordinates, correlated color temperature, u, v and color rendering index. Using Goniophotometer system to measure chromaticity. The SSL product under test in different directions. This can be achieved most efficiently by mounting the color-measuring instrument on a goniometer UNCERTAINTY STATEMENT The uncertainty of the light output measurements is U= 4% (K=2),the uncertainty of correlated color temperature measurements is U=14K(K=2), at the 95% confidence level. This calibration results traceable to the NATIONAL INSTITUTE OF METROLOGY (NIM). Remark: 1. 0 hour season, Pre-heating the lamp for 45 minutes at least; 2. Ambient : 65% RH, 25±1. Pages: 10 of 15
