Recent studies estimate more than 800 million recessed downlights are in operation in the United States, split nearly equally between residential and commercial applications, with about 83% still using incandescent lamps.
Inexpensive compact fluorescent lamp (CFL) downlights are commercially available, but most of these units are not dimmable, which is a desired attribute for many downlight applications. Therefore, energy-saving CFLs often are overlooked in lieu of the functionality of incandescents.
This conflict creates a significant market opportunity for an energy-efficient, dimmable light source designed for the recessed downlight market. Significant energy savings potential exists for long-life LED replacements, as much as 81 trillion watt hours (TWh)
The Solution
Cooper Lighting and the California Lighting Technology Center (CLTC) partnered on this PIER-sponsored project to create an LED recessed downlight suitable for both retrofit or new construction markets that met ENERGY STAR requirements, provided high-quality, broad spectrum light, and could successfully dim on standard analog dimmers. The culmination of this partnership venture was the successful launch of the HALO® LED downlight offered by Cooper Lighting.
Features and Benefits
•The HALO LED recessed downlight is the first ENERGY STAR-rated LED downlight and exceeds the high efficacy requirements set by California’s Title 24 energy regulations
•High color rendering and warm white color temperature: 80 CRI at 3045 K
•Delivers light equivalent to many standard incandescent sources used in recessed downlight applications.
•Up to 25 times longer lamp life than incandescent lamps, lasting up to 68 years in most residential applications and 15 years in typical commercial applications
• Dimmable to 15% of total light output with standard AC incandescent dimmers, 5% with low-end trim adjustment
• Multiple trim options available designed to minimize glare and increase aesthetic appeal, including those for wet applications.
