Cree's new TW Series LED bulb first to meet California Energy Commission specification

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA says that its latest TW (TrueWhite) Series LED bulb emits natural LED light and sets a new standard with a Color Rendering Index (CRI) of 93. Cree’s new TW Series bulb looks like a light bulb, lights like a light bulb, and is available for $19.97 for the 60-watt replacement.

Cree’s TW Series LED bulb is the first to meet the California Energy Commission (CEC) LED bulb specification. The CA specification focuses on six quality attributes for LED lamps, including color temperature, color consistency, color 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 color of the objects it illuminates.

The Sacramento Municipal Utility District (SMUD) has long been a proponent of 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,” said 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.”

“The Voluntary California Quality LED Lamp Specification was created to move consumers away from inefficient lighting of the past century and toward more efficient LED lighting technology,” said Michael Siminovitch, director, California Lighting Technology Center. “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.”

Cree’s new TW Series LED bulb uses 78% 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 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, says the firm (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).
