Advancements in all aspects of fixture design are critical to achieving the full performance of LED technology. How much electricity is consumed depends not only on the LED device, but also on the lighting fixture design, efficiency of the power supply, and the inclusion of features that may degrade source efficiency but have other benefits. Two aspects of energy efficiency are important to consider: the efficiency of the LED device itself (source efficacy), and how well the device and fixture work together in providing the necessary lighting (luminaire efficacy). The DOE long-term R&D goal calls for cost-effective, warm-white LED packages producing 250 to 325Р’В lumens per watt and resulting integrated lighting products of 250 to 275 lumens per watt. But there still remains considerable room for efficacy improvement and widespread deployment of more efficacious products. LED lighting is already the most energy-efficient lighting technology, with efficacies ranging up to 150 lumens per watt or more in some specialized instances. What this all adds up to is the potential to improve the performance and value of lighting in totally new ways. Since LED sources are inherently dimmable and instantaneously controllable, they can be readily integrated with sensor and control systems, thus enabling further energy savings through the use of occupancy sensing, daylight harvesting, and local control of light levels. With many fixture types, including recessed downlights, troffers, and undercabinet fixtures, it is not uncommon for only 50% to 60% of the total light produced to be emitted. In contrast, fluorescent and 'bulb'-shaped incandescent lamps emit light in all directions, with the result that much of the light they produce is lost within the fixture or escapes in a direction not useful for the intended application, or requires pricey and bulky optics to get the light in the right place. This reduces optical losses, which improves efficiency and can enable new, more effective form factors. One of the defining features of LEDs is that their small size and bright output enable good optical control. The ability to dim and provide color control are other benefits of the LED lighting technology platform.

Their unique characteristics-including compact size, long life, resistance to breakage and vibration, good performance in cold temperatures, lack of infrared or ultraviolet emissions, and instant-on performance-are beneficial in many lighting applications. LEDs offer the potential for cutting general lighting energy use nearly in half by 2030, improving resiliency of the grid, saving energy dollars, and cutting carbon emissions in the process.

There can also be improvements in new frontiers of lighting that include energy savings from more effective use of lighting, lighting that promotes health and productivity, and expanded use of controls to deliver just the right light at the right time. The technology can still be improved in efficiency, color attributes, light distribution, form factor, and building integration. But despite this progress, further improvements are both possible and desirable. LED lighting technology now offers the highest luminous efficacies (and efficiencies) of any light-source technology, and low prices have resulted in significant adoption. While many of these products perform quite well, their energy efficiency and color qualities can vary but standards, test procedures, and resources such as ENERGY STAR Р’В®Р’В and the DesignLights ConsortiumРІвЂћСћ Qualified Products List help buyers make informed choices. There are many white LED lighting products available on the market, and the number continues to grow, with new generations of devices constantly emerging.
