About Us

Light Efficient Design, located in Cary, IL, launched our LED light bulb business in 2008, under the ownership of Tim Taylor, a seasoned professional with decades of electrical distribution experience. The company was built upon the strident effort to lead the industry with innovative screw-in LED retrofit manufacturing. Company values include distributor and ESCO relationship loyalty, product quality and innovation. Light Efficient Design is renowned for service excellence.


Our signature product, the screw-in high power LED retrofit for HID fixtures, catapulted us ahead in the market, providing rapid growth and significant recognition on Inc. Magazine and Crain’s Chicago Business ‘Fastest Growing Companies’ lists for several consecutive years. Subsequently, our product line exploded and now includes pin-base retrofits, retrofit kits, fixtures and various specialty solutions.


With a mission to continually evolve, at the start of 2018, Light Efficient Design acquired RemPhos Technologies, of Danvers, MA. Specializing in product customization and environmentally friendly LED lighting, RemPhos has a solid reputation within the lighting industry. Their LED modules, retrofits, luminaires and custom designs are efficiently lighting a broad variety of spaces including hospitals, entertainment facilities, schools and sports complexes. Now partnering together, the new Light Efficient Design can bring superior lighting power to spaces of any kind.


After ten years of success and growth, Light Efficient Design has gone from a company of 3 to a team of over 50 people. We have 10 distribution centers worldwide. Since partnering with RemPhos, the company has production facilities to customize LED products and qualify for ARRA Section 1605 Assembled in America guidelines. Focusing on lighting any commercial space with our unique products, Light Efficient Design is equipped to update any space with efficient solutions.
