30.10.2014 | |

Cree, Inc. introduced the New Cree® LED Bulb, delivering superior light performance while looking just like an incandescent light bulb at an even more affordable price. Featuring a new innovative design, the New Cree LED Bulb provides the same cost savings and 25,000-hour lifetime that made the original Cree LED Bulb America’s best-selling LED bulb. Available as 40- and 60-watt replacements, the New Cree LED Bulb is available at The Home Depot® for as low as $7.97.

“Since the launch of the original Cree LED Bulb, consumers are rapidly switching to LED technology,” said Betty Noonan, Cree chief marketing officer. “Our New Cree LED Bulb goes a step further, delivering even better light performance at a lower price. This new bulb provides consumers a better overall lighting experience which we know drives even more rapid LED adoption.”
