The Cree 8.5-watt LED bulb is designed to replace the old bulbs in your home and business. Thanks to its energy-efficient design, these 5,000K omni-directional bulbs can replace the equivalent of a 60-watt bulb. They provide a rich, natural color in every direction. And because they are fully dimmable, you can create your own unique lighting experience. Cree's silent design also creates as little noise as possible. Each bulb lasts more than 25,000 hours, the equivalent of at least 22 years.
