Sample The following sample was submitted for evaluation: KMW Inc.: LN130-A30 LED HIGH BAY LN130-A30 LED HIGH BAY www.csagroup.com Page 4 of 15
Test Results The following results were measured after stabilization of the sample in the Integrating Sphere (unless otherwise stated). Stability is reached when the variation of 3 readings of light output and electrical power, taken 15 minutes apart, is less than 0.50% (in accordance with IES LM-79-08).

Test Overview In Situ Temperature Measurement: www.csagroup.com Page 11 of 15
The sample was tested in the CSA Atlanta, GA lighting laboratory at a regulated and controlled ambient temperature of 25 C ± 1 C Data was taken on a Fluke 54II calibrated to ISO 17025 The sample was powered continuously from a conditioned 120.0V AC Source (60 Hertz). Temperature data was recorded after 7 hours of operation (stabilization). T c was monitored using a J-Type thermocouple on the manufacturers designated temperature measurement location as shown in the photographs above: Thermocouple Location Temperature Measured ( C) LED Array Center / Driver 42.0 / 38.2 Ambient 25.0 Equipment List: In Situ Temperature Manufacturer and CSA Instrument Description Calibration Due Date Model Number Reference Number Temperature Indicator Fluke 54II TH109 8/2013 All equipment is calibrated to ISO / IEC 17025-2005 guidelines.

Photometric Testing Information The sample was evaluated for photometric and electrical characteristics using an integrating sphere and a goniophotometer, each located in purpose-built, temperature and humidity-controlled, draft free environments. The integrating sphere is by Labsphere which exhibits a 4π geometry configuration according to IES LM-79-08 and is applicable for all types of LED products (directional and non-directional light projections). Its spectroradiometer is an array-type detector manufactured and calibrated by Labsphere. The integrating sphere uses self-absorption correction to eliminate errors due to mismatches between the standard reference lamp and the test samples being measured. The auxiliary lamp used to perform this task is a halogen type lamp powered by a calibrated Lamp Power Supply manufactured and calibrated by Labsphere. Ambient temperature (for photometric analysis) is measured using a J-Type thermocouple located inside the integrating sphere at the same height as the sample under test and not more than 1 meter in horizontal distance away from the sample. The thermocouple is located behind the baffle of the photo detector in order to eliminate any direct optical radiation from the sample under test. Luminaire Stabilization. The sample was placed inside the integrating sphere and powered by a regulated and conditioned Voltage alternating current supply. The correlated color temperature, color rendering index, chromaticity coordinates and electrical power measurements contained in this report are the numeric averages of the three readings upon which stabilization is verified. The stabilization times shown on the results pages of this report denote the time of the 1 st measurement (of the 3 consecutive readings) since this is the minimum time that the sample is assumed to have taken to reach stabilization. The integrating sphere is calibrated using a quartzline halogen lamp with the following specifications: Manufacturer: Sylvania Model# 75Q/CL-28V Voltage = 28.0 Volt Wattage = 75.0 Watts Calibration Current = 2.679 Amperes Luminous Flux = 1538.8 Lumens Calibration Date = 8-18-2005 (calibrated by Labsphere NIST traceable).
