LEDs are quickly being adopted as an illumination solution for general lighting applications. Energy-conscious markets are focusing on high-efficiency LED lighting systems to capitalize on the longevity of solid-state lighting. Cooper Lighting and the California Lighting Technology Center partnered to develop an energy-efficient, sustainable downlight product that is practical for multiple lighting applications in the home.

The project integrates dimmable LEDs into a recessed downlight to achieve an overall system that has a high lumen output while providing continuous dimming control and low power consumption. The LED downlight's optical design yields more productive beam lumens and good cutoff.
