Energy Savings Estimates of Light Emitting Diodes in Niche Lighting Applications

Light Emitting Diodes (LEDs), a type of Solid State Lighting (SSL), offer the electric lighting market a new and revolutionary light source that saves energy and improves quality, performance, and service. Today, LEDs are competing successfully with conventional, incandescent light sources that use color filters to generate the desired colored light emission, such as those found in traffic signals and exit signs. In these and other applications, consumers choose LEDs because they offer more cost-effective performance than incandescent lamps. This report presents research findings for twelve different niche markets where LEDs are competing or are poised to compete with traditional light sources, such as incandescent, halogen, fluorescent, neon, and high-intensity discharge (HID). LEDs are challenging traditional light sources, because the LED offers lower operating costs and better reliability and performance. This report presents estimates of the energy saved due to estimated current levels of LED market penetration. This report also estimates the 'overnight' technical potential energy savings if these markets switched completely to LEDs. This study found that the applications where LEDs have the highest level of market penetration are colored-light applications such as traffic signals, exit signs, holiday lights and electric signage. In these installations, LEDs have the advantage of only producing light in the color of interest to the end-user, thus they can do so more efficiently and reliably than filtered full-spectrum sources. The applications where market adoption is maturing or poised to grow include traffic signals and pedestrian crossings, decorative holiday lights, exit signs, electric signage, and refrigerated display case lighting. The applications where market adoption has yet to occur, but for which high quality LED products are currently available include recessed downlights, retail display, task lights, office undershelf and kitchen undercabinet lights, street and area lights, and outdoor step, path, and porch lights.
