Cypress Semiconductor Corp. has announced that its LED power controller inside LED replacement lamps from MSi are helping to drive energy savings inside Macy's stores around the country.

Macy's is replacing about 117,000 traditional incandescent light bulbs in 86 stores with new LED lamps that use about 73 percent less energy. Total energy savings are estimated at about 16,200 megawatts per hour every year, the equivalent of planting more than 65,500 trees. The LED lamps have an expected life of 10 years (compared with less than one year for traditional bulbs), reducing landfill disposal, Cypress said.

"It's exciting to see our technology deliver significant benefits in a major project such as Macy's retrofit," said Brian Moody, director of Marketing for Cypress's PowerPSoC business. "As more companies see the tangible benefits of LED lighting, we can see a snowball effect leading to significant growth in which we are well positioned to participate."
