Project Info COMPLETE Project Title

LED A-Lamp Laboratory Assessment

Project Number ET10SCE1290 Organization SCE End-use Lighting Sector Residential Project Year(s) 2010 - 2010
Description
This laboratory evaluation is aimed at understanding the performance of LED A-19 replacement lamps. The lamps will be tested for light output, color consistency, energy use and overall efficiency.
Project Results
Southern California Edison (SCE) conducted this light-emitting diode (LED) A-19 lamp Emerging Technologies (ET) Assessment Project in order to determine the energy savings, performance, the availability of the LED A-19 lamp. In addition, the study determines whether the LED A-19 lamp meets the Energy Star® minimum requirements. A-19 lamps refer to the common household lamp with a standard Edison screw-base used in fixtures such as table lamps, floor lamps, and general lighting fixtures where omni-directional light is needed. This project assesses the LED A-19 lamp's ability to replace the incumbent incandescent technology by studying five separate metrics for 77 different A-19 lamps. The metrics were color rendering index (CRI), efficacy (lumens/watt), light output (lumens (lm)), correlated color temperature (CCT), and power factor (PF). The data for 56 A-19 lamps was obtained from the U.S. Department of Energy's (DOE) Solid State Lighting (SSL) Lighting Facts program. LightingFacts.com is a DOE sponsored website that reports the LED performance according to industry standards that are listed by manufacturers’ names and model number. i The remaining 21 LED A-19 lamps were tested in SCE's Lighting Technology Test Center (LTTC) in order to determine their performance using the same metrics. The 21 LED A-19 lamps were chosen by purchasing all available lamps through online retailers.
