2. Scope of testing
‐Photometric and electrical testing in accordance with IESNA LM 79 2008 IES (ApprovedMethod: Electrical and Photometric Measurements of Solid-State Lighting Products).All measurements are made using the goniophotometer / spectroradiometer test method.
The spectral values are measured at a given direction with vertikal angle theta= 0°.
Date of test: 14.10.2015
Report and test prepared by: Kranhold / ILEXA GbR
3. Equipment
‐Testing is performed in accordance with the procedures outlined in IESNA LM79 2008.The sample is evaluated for photometric and electrical characteristics using a goniophotometer,located in an temperature - controlled, draft free photometric laboratory.
