  • 3. White Paper:TFM 2.12.10Executive SummaryProblem: Lighting in commercial buildings account for over 70% of the overall lighting elec-tricity used in the United States. Rising energy and maintenance costs are hurting profits ofcommercial and industrial facilities and their carbon emissions must be dramaticallyreduced to halt global warming issues.Background: Increasing energy efficiency in lighting systems will impact reducing the overallenvironmental effects, such as greenhouse gas emissions, and CO2 emissions. The reducutionof greenhouse gas emissions and an energy-efficiency focus will be crucial to businesses inthe United States if the Federal Climate Change Waxman-Markey Bill passes, as businesseswill be taxed on greenhouse gas emissions.Solution: LED lighting offers significant energy, maintenance and recycling savings. Whenretrofitting with LEDs, with good lighting design and LED product selection, energy con-sumption in most commercial and industrial facilities will be cut 50-80% while maintainingimproving lighting quality. Three factors are accelerating for the use of large scale deploy-ment of LED products for general area lighting applications: 1) Retrofitting an existing lighting system with quality LEDs will make the facility more energy efficient and yield costs. LEDs have the best return on investment (ROI) of any energy-efficient technology. 2) The aesthetic quality of a facility’s environment will be enhanced and productivity increased without sacrificing the lighting system performance. 3) Federal and state governments are making laws regarding lighting, and associations are taking action towards quality products. All to make the United States more energy efficient and responsible. With support and encouragement through grants, and departments such as the DOE, an LED lighting system becomes even more advanced and cost effective. LED Lighting Retrofits 1

Superior lighting quality LEDs light up very quickly and are ideal for use in applications that are subject to frequent on-off cycling. Comparing LEDs to other light- ing technologies, fluorescent lamps tend to burn out more quickly when cycled frequently, where HID lamps require a long time before restarting. LEDs can very easily be dimmed either by pulse-width modulation or by lower- ing the forward current. In contrast to mostLEDs - A Better Light Source light sources, LEDs radiate very little heat in the form of infrared (IR) that can causeLEDs create a better environment damage to sensitive objects or fabrics.

LED lighting retrofits will save commercial and industrial facilities on operating, maintenance and energy costs. To fully realize the cost savings, energy efficiency, and low mainte- nance LEDs offer, it is important to convert to LED with the most advanced and capable technology on the market. With performance, lifetime, cost, safety, and theft-deterrence advantages, LED lighting is the best choice when retrofitting with energy efficient tech- nology. Depending upon the technology being replaced, potential energy savings, rebates, and incentives, a lighting retrofit could be a low-cost implementation.
