Sample

The following sample was submitted for evaluation:

KMW Inc.: LN160-A30 LED HIGH BAY

LN160-A30 LED HIGH BAY

Report: 2594747

Project: 2594747





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

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).

Tc was monitored using a J-Type thermocouple on the manufacturers designated temperature

measurement location as shown in the photographs above:

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 1st 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).
