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.
