Light Fixture Retrofits

Light fixtures and our understanding of electricity have come a long way from light bulbs hanging from wires on the ceiling. You wouldn’t choose a phonograph over an iPod would you? So why let old light fixtures drive your electric bill up when there are better options? MJW can retrofit your home with light fixtures designed to save electricity. Use new LED low wattage bulbs in your new fixtures to create a truly energy efficient house. For commercial applications we offer energy audits replacing T-12 light fixtures to LED or high-efficiency T-8 along with smart controllers for heating and HVAC systems that could save your business thousands of dollars a year. Relatively low-cost motion sensors installed in a bathroom can save additional hundreds of dollars a year. Many times these upgrades also make you eligible for rebates from your local utility company.
