LED Lamp Specification was created to move consumers away from inefficient lighting of the past century

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,” 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,” said Brinton.

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 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.”


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.
