For as long as I have been in this industry, material substitutions have been a way to save money on projects. The process eventually became known as “value engineering.” Theoretically, the contractor, and maybe the owner, saves money by replacing a specified product with a less costly one.
While the light-emitting diode (LED) has gotten a lot of attention in recent years, another revolution has quietly developed in the background: intelligent (digital) lighting control. The future of lighting is solid-state, and it will be highly controlled.
The 2008 housing-market crash ended the home construction boom. A steady recovery began in 2012, and it continues today, bolstering the U.S. economy. Historically, residential construction averages 5 percent of the country’s gross domestic product.
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.
For several years, I have been seeing a new hole in the theoretically 100-percent-complete electrical drawings we are provided for bidding. Within the last year, the problem has gotten bigger, driven by increasingly strict energy-usage requirements.
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.
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).
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.
The Light-emitting diode (LED) seems to be everywhere, including in tiny keychain flashlights, conventional flashlights that emit powerful beams, general service lamps, replacement fixtures for commercial use, and portable work lights.
