Dialight is the world leader in LED industrial lighting technology with millions of LED fixtures installed worldwide. Our story began in 1938 in Brooklyn, NY, where we produced instrument panel lights for aircraft. In 1971, just one year after the introduction of the LED, we launched our first LED product. Since then, we have revolutionized the use of LEDs and ONLY LEDs, to provide superior lighting for traffic control, indicators, structural towers and industrial work sites around the world. Learn more about our products and people in our company video.

Our customers operate their businesses in harsh industrial environments requiring advanced lighting that is efficient, supports productivity, and above all, ensures the safety of their employees.

Traditional lighting technologies such as Metal Halide, Fluorescent and High Pressure Sodium, require significant and frequent maintenance. Work sites and plants must stock many different types of lamps, ballasts and other fixture components to maintain these systems. These older technologies have short lifespans, poor lumen maintenance and contain material harmful to our environment. When designed properly, LED systems can offer superior energy efficiency, reliability, longevity, improved light levels, visual clarity, and ultimately cost savings from reduced or eliminated lighting related maintenance, certified lamp recycling and of course energy costs.

That’s why we specialize ONLY in LED lighting.
