lighting of the past century and toward more efficient LED lighting technology,” said Michael Siminovitch, director, California Lighting Technology Centre. “The new Cree TW Series is the first bulb to meet the CA Specification and is exactly what consumers need to see in order to finally transform this marketplace.”
The new Cree TW Series LED Bulb delivers an unprecedented 93 CRI. The high-performance bulb uses 78 percent less energy and lasts 25 times longer than typical incandescent light bulbs. The bulbs turn on instantly, are dimmable with most standard incandescent dimmers and are backed by Cree’s industry-leading 10- year limited warranty. With a retail price of $17.97 for the soft white 40-watt replacement (450 lumens) and $19.97 for the soft white 60-watt replacement (800 lumens), the Cree bulb quickly pays for itself then pays consumers year after year.*
“The new TW Series is a great complement to our market-leading Cree LED Bulb that was launched in March and gives consumers more reasons to switch to LED lighting,” finishes Chuck Swoboda, Cree chairman and CEO. “The Cree TW Series LED Bulb is another example of Cree’s commitment to innovation and driving 100 percent adoption of LED lighting.”
*Based on Cree TW Series LED Bulb 60-watt replacements at 13.5 watts, $0.11 per kilowatt-hour, 25,000 hour lifetime and average use of six hours per day.
Cree LED lights brighten up Raley’s Petroleum and Convenience Store
The firm’s LED lighting delivers savings and rapid payback at a New South Lake Tahoe location
Raley’s Family of Fine Stores has selected LED lighting by Cree to illuminate its new petroleum station, car wash and convenience store in South Lake Tahoe, California.
Featuring advanced LED technology paired with an integrated dimming system, Cree lighting delivers improved light quality combined with reduced energy consumption and maintenance costs for the store, with payback in less than one year.
This is based on typical commercial usage of 12 hours per day for exterior products and 24 hours per day for interior products, and the state of California average of $0.14 per kWh electric costs, lighting-related HVAC impact and relamp maintenance reductions.

Sixty Cree LED luminaires illuminate the South Lake Tahoe store, generating significant energy savings compared to the fluorescent, metal halide and halogen fixtures used at Raley’s existing Fair Oaks, California location. Cree’s interior and exterior fixtures deliver exceptional colour rendering, light quality and distribution and allow the use of fewer fixtures than required with traditional lighting.
The new Cree lighting system includes Cree 304 Series recessed soffit luminaires and Cree CR24 troffers in the convenience store along with Cree 304 Series recessed canopy luminaires installed over the fuel canopy deck and Cree 227 Series recessed soffit luminaires in the car wash bay.
Cree Edge wall-mount security luminaires, as well as post-top and arm-mounted luminaires provide further exterior lighting in the parking lot.
“Implementing energy-efficient LED lighting supports our goal of reducing overall energy consumption at new stores and in upgrades to our 128 locations,” says Randy Walthers, energy and utility manager, Raley’s. “We found a valued partner in Hi-Def Lighting & Electrical, Inc. who met our needs with high-quality Cree LED lighting equipped with a sophisticated control system for remarkable savings and light quality.”
Featuring an optional integrated sensor, Cree luminaires help Raley’s conserve energy and meet California’s daylight control requirement at the South Lake Tahoe store. Cree luminaires in the car wash, for example, operate at 20 percent power until the occupancy sensor brings them to full power and then dims them when not in use.
An additional benefit of the Cree lighting installation is the universal drivers that provide continuous illumination during periodic brownouts that are common to the area.
“In South Lake Tahoe, the voltage will drop as much as 30 percent during hot afternoons creating multiple problems with electrical systems,” comments Walthers. “Cree luminaires are unaffected by these erratic voltage drops and continue performing at peak efficiency due to dependable drivers that include AC input protection.”
“Raley’s is fast becoming a model of energy efficiency in the petroleum and convenience store industry,” adds Mike Bauer, vice president sales, lighting at Cree. “Cree offers a full suite of energy-efficient lighting for 24/7 operations, helping Raley’s continue its mission toward environmental stewardship, while supporting their bottom line.”
