Energy Efficient LED Lighting and Technologies

Rapid advancements in LEDs and the global need for energy efficient lighting alternatives are creating opportunities to replace conventional light sources with LED lighting for general illumination. LED lighting is gaining momentum for many reasons, and chief among them is energy efficiency.

With the landmark signing of the Energy Policy Act of 2005, and other nations similarly devoting resources to energy conservation, the potential impact of LED lighting is increasingly gaining national and global attention. A 2001 Department of Energy study estimated cumulative savings of $98 billion by 2020 once LED lighting reaches the performance crossover with conventional sources. Philips Solid-State Lighting Solutions believes this day is approaching faster than ever anticipated.

Today Philips’ energy efficient lighting systems deliver big visual impact without the big energy drains. Yet LED lighting can achieve energy savings on a much larger scale as it becomes more applicable to general illumination. With the introduction of EssentialWhite™ and IntelliWhite™, Philips now addresses specialty white light applications while developing systems that will meet the growing opportunity to cost-effectively apply LEDs for general illumination.

Energy Costs
Energy consumption reduced from 8,000 watts to 600 watts total

The Ponca City Memorial Fountain has long been a community focal point, engaging residents and visitors since its construction in 1925. When the fountain was last renovated in 1980, the lighting scheme called for 250-watt incandescent fixtures with red, green and blue lenses to create colored effects. This resulted in a maintenance challenge and little ability to actually control the illumination.

Cost of Light

The opportunities to replace conventional lighting with LED lighting for general illumination are growing, fueled in part by the continual advancements in LEDs and the global need for energy-efficient lighting alternatives. Performance is an important metric for assessing the viability of replacement by LED sources. These devices that once merely lit calculators and cell phone displays can now illuminate an airport terminal or a 100 foot building façade. They increasingly match or exceed the efficacy of conventional lighting sources, particularly with the advent of today’s power LEDs. In fact, the efficacy of LED sources, measured in lumens per watt, is eclipsing that of incandescent and halogen sources.As a result, Philips Solid-State Lighting Solutions’ systems are displacing conventional lighting methods in a number of applications where LEDs were previously thought impractical. And this exciting trend continues. Performance is improving rapidly in the intensely competitive LED supplier field where current data from these manufacturers shows LED performance ahead of forecasted levels, and the cross over point for matching the efficacy of fluorescent sources outpacing the predictions made just a few years ago. Yet performance is only one metric.Matching the cost of conventional lighting is another critical element for replacement to occur. The true measure of cost goes beyond just the initial cost of the lighting system and incorporates lifetime and operational costs as well. For example, an incandescent source may only have an initial cost of fifty cents, yet its energy consumption will cost more than ten times that over its relatively short life, when a new source must be purchased and the cycle starts again. The metric that accounts for all of these factors is called the Cost of Light. This is the measure that sophisticated customers, such as those managing large buildings, use to compare the true cost of illumination. Intelligent LED lighting systems are intersecting the Cost of Light of incandescent and halogen sources and are rapidly approaching the economic cross over point for fluorescent sources. A white paper is available for more detailed information.

These are Philips estimates, and are not indicative of future performance. Decreasing operational and lifetime costs, together with improved LED performance, enable a wide spectrum of new applications.

  1. Adriana,
    I have been comparing many avenues of energy conservation sources and products. your post on LED lighting is great.
    With the controversy surrounding CFLs, the advancing LED lighting technology has unlimited potential to not only reduce energy consumption dramatically, but help with the many concerns related to mercury contamination If CFLs are not disposed of properly.

      Hello, and thank you for taking the time and reading about the energy saving article. It is very important taking time and choosing smart products.Better choices start at our own home than to the outside.I hope with recession people take time to think about 360* ideas.
      Be well, Shop smart!
