TEST OBJECTIVES This report aims to provide the comparative energy performance of Incandescent, CFL and LED lights. III. TEST METHOD Samples were tested using energy consumption monitoring. IV. GENERAL TEST CONDITIONS a. Test Environment No specific environmental condition for the test. Ambient conditions are not controlled and are just noted for record purposes. b. Power Supply Power supplied on the measuring instrument and test units was regulated and maintained at 230 Volts AC ±2%. c. Measuring Instruments Electrical parameters (voltage, current, power) were measured using Power Quality Analyzer (PQA) LEM Memobox 300. 1|Page MERALCO POWER LAB Test Date: 2014-04-28 Report Date: 2014-05-12 CUSTOMER SOLUTIONS & PRODUCT DEVELOPMENT V.
