Project Title 
Directional LED Lamps - Laboratory Testing Program
Project Number 
Investor Owned Utilities 
Project Year(s) 
2011 - 2012

The goal of this project is to establish a laboratory testing program to verify or refute light emitting diode (LED) manufacturer’s product claims regarding life, lumen and color maintenance of directional LED replacement lamps for use in the retail market. Test results will be provided to the Pacific Gas & Electric (PG&E) team for use in their effort to prepare for the promotion and use of LED replacement lamps in their service territory.

The LED lamps involved in this test program include an assortment of MR16, PAR20, PAR30, and PAR38 replacement lamps. These lamps represent a cross section of available lamp characteristics including:
• Power (Watt)
• Luminous Flux
• Correlated Color Temperature (CCT)
• Color Rendering Index (CRI)
• Dimmability
• Life Time

Operating conditions will be controlled and monitored throughout the duration of the testing program. Controlled conditions include temperature, orientation, duty cycle, and dimming level. A data acquisition system will monitor each lamp’s electrical characteristics and operating time.

Test results will verify or refute manufacturer claims regarding the following characteristics:
• Lamp Life
• Lumen Maintenance
• Color Maintenance
