Trust. “No other manufacturer offered the combination of performance, pricing and efficacy we desired. We continue to be impressed by the improved lighting quality and significant savings the CR22 troffers provide.”


Featuring Cree TrueWhite Technology, Cree linear luminaires enabled Piedmont Office Realty Trust to reduce the fixture count by 10 percent, adding to the overall savings. Designed to last for more than 50,000 hours, twice the lifetime of comparable linear fluorescents, the new fixtures are designed to reduce maintenance and operational costs for the headquarters.


The CR22 troffers feature integrated Lutron EcoSystem dimming technology. The system is controlled by a Lutron Quantum lighting control system, which provides the flexibility needed to reconfigure and improve the occupant experience in any space and can extend LED lifetime.


The ability to fine-tune light levels individually in each fixture, and ultimately to achieve the perfect lighting environment, is the result of an ideal marriage between the Cree luminaires and Lutron digital control technology.


“The CR Series is a no-compromise alternative to fluorescent lighting and demonstrates our commitment to driving the broad adoption of LED lighting,” says Mike Bauer, vice president of lighting sales, Cree.


“The successful integration of CR troffers with digital controls and dimming allows Cree to further the obsolescence of antiquated fluorescent lighting. Optimal lighting is essential to workplace environments like NASA’s headquarters. Cree linear luminaires deliver unrivalled performance, making the decision to choose LED lighting over fluorescent options an obvious choice.”


Cree raises the bar for standard LED bulbs


The firm’s III-nitride based LED bulbs are suitable for use in 60W replacement bulbs


Cree’s TW (TrueWhite) series LED bulb emits natural LED light - setting a new standard with a Colour Rendering Index (CRI) of 93.


Cree says it is the first company to meet the California Energy Commission (CEC) LED bulb specification.


The new TW Series bulb looks like a light bulb, lights like a light bulb and gives consumers another reason to switch to LED. The new Cree bulb is available for $19.97 for the 60-watt replacement.

California is yet again leading the nation with a higher standard for energy efficiency - this time it’s across the lighting industry. The introduction of Compact Fluorescent Lighting (CFL) led to a backlash of consumer dissatisfaction for many reasons, the greatest being its failure to provide Californians a quality lighting alternative to inefficient incandescent technology.


New technology, like the new Cree TW Series LED Bulb, offers CA consumers a no-compromise alternative to CFL and incandescents.


The Sacramento Municipal Utility District (SMUD) has long been a proponent for energy-efficient lighting technologies for its customers. SMUD will provide a rebate for the new Cree TW Series LED Bulb. “SMUD sees huge value in reducing the lighting portion of electric bills and is a staunch supporter of the new CA LED Quality lighting standard,” says Elisabeth Brinton, SMUD Chief Customer Officer. “We are thrilled to see the first bulbs reach the market. This technical accomplishment makes a huge contribution to energy efficiency, while benefiting consumers with quality lighting,” says Brinton.


The CA specification focuses on six quality attributes for LED lamps, including colour temperature, colour consistency, colour rendering, dimmability, lifetime and light distribution. The new CA standard requires all retrofit lamps to achieve a CRI of 90 or better – the higher the CRI of a bulb, the more accurate the actual colour of the objects it illuminates.


“The Voluntary California Quality LED Lamp Specification was created to move consumers away from inefficient
