REPORT 3933 US ROUTE 11 CORTLAND, NEW YORK 13045 Project No. G100225920 Date: October 29, 2010 REPORT NO. 100225920CRT-001 TEST OF ONE LED DESK LAMP FIXTURE MODEL NO. ADAPTER MODEL NO. JY15-240-050-UD RENDERED TO KONCEPT TECHNOLOGIES 2570 CORPORATE PLACE SUITE E101 MONTEREY PARK, CA 91754-7634 TEST: Electrical and Photometric tests as required to the IESNA test standard. LABORATORY NOTE: The laboratory that conducted the testing detailed in this report has been Qualified, Verified, and Recognized for LM-79 Testing for ENERGY STAR for SSL by US DOE's CALiPER program. AUTHORIZATION: The testing performed was authorized by signed quote number 500258806. STANDARDS USED: The following American National Standards or Illuminating Engineering Society of North America Test Guides were used in part or totally to test each specimen: IESNA LM-79: 2008 Approved Method for Electrical and Photometric Measurements of Solid-State Lighting Products ANSI NEMA ANSLG C78.377: 2008 Specifications of the Chromaticity of Solid State Lighting DESCRIPTION OF SAMPLE: The client submitted one sample of model number. The sample was received by Intertek on September 21, 2010, in undamaged condition, and one sample was tested as received. The sample designation was K7398L. DATES OF TESTS: October 20, 2010 through October 29, 2010. This report is for the exclusive use of Intertek's Client and is provided pursuant to the agreement between Intertek and its Client. Intertek's responsibility and liability are limited to the terms and conditions of the agreement. Intertek assumes no liability to any party, other than to the Client in accordance with the agreement, for any loss, expense or damage occasioned by the use of this report. Only the Client is authorized to copy or distribute this report and then only in its entirety. Any use of the Intertek name or one of its marks for the sale or advertisement of the tested material, product or service must first be approved in writing by Intertek. The observations and test results in this report are relevant only to the sample tested. This report by itself does not imply that the material, product, or service is or has ever been under an Intertek certification program. Measurement uncertainty budgets have been determined for applicable test methods and are available upon request.

Photometric and Electrical measurements Distribution Method A LSI Type C High Speed Model 6440 Mirror Goniometer was used to measure the intensity (candelas) at each angle of distribution for each sample. Ambient temperature was measured equal to the height of the sample mounted on the Goniometer equipment. Each sample was operated at input rated voltage in its designated orientation. Each sample was allowed to stabilize for at least thirty minutes before measurements were made. Electrical measurements including voltage, current, and power were measured using the Xitron or Yokogawa Power Analyzer. Some graphics were created with Photometrics Plus software.
