3 Report No.: EASZE Page 3 of 14 3 TEST METHODS 3.1 Requirements of Ambient Condition The ambient temperature in which measurements are being taken shall be maintained at 25 ± 1, measured at a point not more than 1 m from the SSL product and at the same height as the SSL product. Air flow around the SSL product being tested should be such that normal convective air flow induced by device under test is not affected. 3.2 Seasoning of SSL Product For the purpose of rating new SSL products, SSL products shall be tested with no seasoning. Therefore, no seasoning was performed. 3.3 Stabilization 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 minutes for small integrated LED lamps to 2 or more hours for large SSL luminaires. 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 minutes, taken 15 minutes apart, is less than 0.5%. Therefore, the stabilization time of the sample was 1 hour, and the total operating time including stabilization was 3 hours. 3.4 Operating Orientation The SSL product under test shall be evaluated in the operating orientation recommended by the manufacturer for an intended use of the SSL product. Stabilization and photometric measurements of SSL products shall be done in such operating orientation. Therefore, the orientation of the sample as mounted for measurement was shown in Section 4.2 figure. 3.5 Photometric and Electrical Measurements - Goniophotometer Method An EVERFINE Type C Model GO-R5000 Goniophotometer was used to measure the intensity at each angle of distribution for each sample. The photometric distance is 2.1m for near-field measurement or 26m for far-field measurement. Ambient temperature was measured at the same height of the sample mounted on the Goniophotometer equipment. Electrical measurements including voltage, current, and power were measured using the Digital Power Meter. Some graphics were created with Photometric Plus software.

4 Report No.: EASZE Page 4 of Color Characteristics Measurements The color characteristics of SSL products include chromaticity coordinates, correlated color temperature, and color rendering index. These characteristics of SSL products may be spatially non-uniform, and thus, in order that they can be specified accurately, the color quantities shall be measured as values that are spatially average, weighted to intensity, over the angular range where light is intentionally emitted from the SSL product. The color characteristics measurements are using gonio-spectroradiometer. 3.7 Color Spatial Uniformity The characteristics of SSL products may be spatially non-uniform, the chromaticity coordinate shall be measured at two vertical planes (C=0 /180 and C=90 /270 ) and at 10 or less intervals for vertical angle until the light output dropped to below 10% of the peak intensity. The averaged weighted chromaticity coordinate was calculated from these points. The data was then analyzed to check for delta color differences of the u', v' chromaticity coordinates. The spatial non-uniformity of chromaticity, u'v', is determined as the maximum deviation (distance on the CIE (u', v') diagram) among all measured points from the spatially averaged chromaticity coordinate. The geometry for the chromaticity measurement using gonio-spectroradiometer is shown as following.
