Hybrid Smart Entry Luminaire |
Many exterior entry and walkway lights in residential and commercial applications use incandescent lamps because they are small and inexpensive. However, they are inefficient and burn out quickly—typically four times per year if operating all night—causing high operational and maintenance costs and security concerns.
Researchers from California Lighting Technology Center (CLTC) partnered with Watt Stopper / Legrand and Hunter Lighting Group to develop the Hybrid Smart Entry Luminaire. Long-life light emitting diode (LED) technology is combined with an occupancy sensor and a fluorescent lamp, reducing operating costs below incandescent lamps and even standard CFL fixtures.

OBJECTIVE:
To develop a cost-effective luminaire to be used in new construction and renovation projects for residential, commercial, and institutional applications
APPLICATIONS:
- Entryways and exterior path lighting
DESCRIPTION / FEATURES:
- Energy savings: Operating costs can be reduced by 60% to 90%
- The combination of LED, fluorescent lamp, and occupancy sensor uses less energy than CFLs alone
- Continuous LED lighting eliminates dark spots commonly associated with motion sensor systems
- LEDs with 10-15 year life provide light when incandescent lamps burn-out
- Reduced lamp operation results in lower maintenace costs

RESULTS:
- The luminaire is most cost effective when used in new construction and renovation projects
- Significant energy savings, lower maintenance costs, and increased user safety
- Hybrid Smart Entry Luminaire may be used in some pathway applications
STATUS: The University of California/California State University (UC/CSU) and Investor-Owned Utility (IOU) Partnership Program has identified incentives for this technology that range from $10 to $65 per fixture.
Watt Stopper/Legrand will have a commercially available product that is expected to be available by late 2008.
