Lighting Sciences, Inc. (LSI) Testing Information The following information was taken directly from the LSI Lab Report:

INDEPENDENT TEST LABORATORY REPORT No. 31606A HOWARD INDUSTRIES INC - VAPOR TIGHT LUMINAIRE,CAT# VHL2F67219540USVY10I

WITH WHITE INTERIOR AND FROSTED PLASTIC DROP LENS 672 LEDS. LUMINAIRE OUTPUT = 17039 LM

LUMINAIRE OPERATING AT 120 VAC AND 223 WATTS LUMINOUS OPENING SIDE VIEW.

All testing was conducted in accordance with LM-79-08,

Approved Method: Electrical and Photometric Measurements of Solid-State Lighting Products as published by the

Illuminating Engineering Society of North America (IESNA).

The condition of the item tested was new. Stabilization time before testing meets the stabilization requirements

of LM-79-08.

The test results (luminous distribution and flux) were obtained by using a Lighting Sciences series

6000 Type C Moving Mirror Goniophotometer

The photometric reference standard used is a set of three incandescent luminous intensity standard lamps calibrated

and traceable to the U.S. National Institute of Standards and Technology.

The test results (colorimetric and luminous flux) were obtained by using a Labsphere Model LMS-760 Integrating Sphere.

4π geometry was used. Correction factors were applied for self-absorption.

The colorimetric & photometric reference standard used is an incandescent spectral flux standard lamp calibrated and

traceable to the U.S. National Institute of Standards and Technology.

Power measurements were obtained with a Yokogawa WT210 power analyzer. Ambient temperature during testing was

25⁰ C ± 1⁰ C, measured using an Omega model DP460.

Calibration certificates are on file at the laboratories of Lighting Sciences Inc.

The results in this report apply to the test sample(s) mentioned in this report at the time of the testing period only and are

not to be used to indicate applicability to other similar products.
