From making clothing look vibrant in a retail store to facilitating interaction in offices by properly rendering skin tones, a light source's color quality is an important specification characteristic. For this, we use two metrics, correlated color temperature and the color rendering index (CRI).
On Feb. 12, the Department of Energy (DOE) proposed an efficiency standard for general service lamps, marking the next step in an ongoing process that started with the passage of the Energy Independence and Security Act (EISA) in 2007.
The Global Lighting Challenge (GLC) was launched in May 2015 as a vehicle to help achieve the goal of cumulative global sales of 10 billion high-efficiency, high-quality and affordable advanced lighting products, such as light-emitting diode (LED) lamps.
Solid-state lighting, such as light-emitting diode (LED) technology, promises significant short-term opportunities, notably in the retrofit market. However, many industry stakeholders are concerned about long-term risks LEDs present as they continue to gain acceptance.
While street lighting improves traffic safety by enabling pedestrians and motorists to see each other, it also contributes to aesthetics. Landscape lighting enhances security and accents special features to create a unique atmosphere for outdoor events.
The organic light-emitting diode (OLED) continues to develop alongside the light-emitting diode (LED). This light source’s intriguing capabilities position it as a strong potential alternative to LEDs for certain applications.
With an estimated 1–2 billion fluorescent sockets installed in commercial, industrial, institutional and retail applications across North America, the market for T8 technology remains strong, though new LED T8 replacements are giving traditional fluorescent technology a run for the money.
A number of cities have embraced light-emitting diodes (LEDs) as an efficient street lighting technology. Making the transition is not a simple endeavor, and the U.S. Department of Energy’s (DOE) Gateway Demonstration program helps them evaluate the technology.
Lighting an iconic Ferris wheel is not an electrical contractor’s usual task. However, Briggs Electric Inc. of Tustin, Calif., faced such a challenge when the company took on the unusual project of the Giant Wheel at Irvine Spectrum Center.
Multifunctional sensors, networked wireless controls accessible from mobile devices, and, yes, light-emitting diodes (LEDs) are trends that picked up steam this year. These interconnected technologies will be transformational for the electrical contractor (EC).
High-value specialty crops, such as fruits, vegetables and ornamentals, account for a tiny percentage of U.S. farmland but yield about 40 percent of farmland revenues. In many regions, these crops are grown in shielded environments, such as greenhouses.
According to The Washington Post, the number of wineries around the United States has grown from about 2,000 in 2000 to approximately 8,000 in 2014. In addition, while they tended to be limited to a handful of states 15 years ago, every state, including Alaska, now boasts at least one winery.
Mark S. Rea, Ph.D., professor and director of the Lighting Research Center at the Rensselaer Polytechnic Institute, believes the lighting industry has a problem. Solving it first requires an admission that it exists.
Thanks to advanced lighting controls, various industries view lighting as an important element in energy-efficient design. It is a business-intelligence platform that combines sensors and systems in a way that provides excellent illumination and energy savings.
