The U.S. Department of Energy (DOE) recently issued three reports that provide a snapshot of several light-emitting diode (LED) lighting markets and estimate potential energy savings for full adoption.
Department of Energy statistics reveal that approximately 22 percent of all electricity generated in the United States is used for lighting, and about 10 percent of that is used to power outdoor lighting applications.
If your sales pitch regarding light-emitting diode (LED) technology is that it lasts forever, uses less power and is cheaper to operate, keep going. Establishing the rate of return on investment (ROI) for solid-state lighting (SSL) is more varied and expansive than you might think.
When a particular technology catches on, it can touch every aspect of daily life. Even the most mundane of functions can be transformed. Light-emitting diodes (LEDs) are no exception, and they continue to flex their muscle in new and innovative ways.
Despite their relatively high upfront cost, light-emitting diodes (LEDs) are consistently hailed as the next generation of efficient lighting technology. Most experts agree there is no question that LEDs will take the lead in general service lighting.
Lighting upgrades have long been recognized as one of the easiest, most cost-effective ways to cut a building’s energy use. Efficiency requirements are making some of these projects a necessity, as, for example, replacement T12 fluorescent lamps disappear from the market.
Among the industries seeking ways to make technology smaller, lighting is no exception. Now, a team of scientists at the University of Strasbourg in France has developed the first single-molecule light-emitting diode (LED).
In late 2012, the California Energy Commission (CEC) published a voluntary specification recognizing quality light-emitting diode (LED) lamps intended to replace screwbase incandescent lamps in luminaires.
The benefits of light-emitting diodes (LEDs) as a brighter, more efficient alternative to fluorescent lamps have become common knowledge. It may only be a matter of time before LEDs become the lighting source of choice for consumers.
The opportunity in the LED retrofit market is enormous, and the missteps made in rushing other energy-efficient lighting to market (e.g., the compact fluorescent lamp) are less likely to slow market growth this time around.
Fixture by fixture, lighting in American cities is transitioning from the traditional metal halide domain to light-emitting diodes (LEDs), not only on city streets, but also in landscaping and commercial building settings.
At the Electric Power Research Institute (EPRI), researchers recently released findings from a study of light-emitting diode (LED) street lighting technology. What they found should be of interest to electrical contractors.
While Light-emitting diode (LED) general lighting continues to rapidly develop and transform the lighting industry, the organic LED light source, or OLED, offers equally dramatic possibilities. Let’s look at the current status of this remarkable technology.
Wireless technology is certainly getting attention these days. We’ve covered the extensive range of new home automation and security products and systems often here in the pages of ELECTRICAL CONTRACTOR.
In any lighting system, lamps and auxiliary electrical devices fail and must be replaced. Dirt and dust accumulates on fixture surfaces and should be cleaned. System problems must be corrected, and lighting controls should be adjusted as space conditions change.
It’s hard to imagine anyone in the electrical industry seriously questioning the fact that light-emitting diode (LED) technology and solid-state lighting (SSL) are becoming the light source choice of the future.
