As thousands of attendees gathered at the Lightfair International Conference in Las Vegas on May 10, 53 commercial light-emitting diode (LED) indoor lighting products were recognized and awarded in the fourth annual Next Generation Luminaires (NGL) solid-state lighting design competition.
On the May 14, 2012, Washington, D.C., Mayor Vincent Gray joined officials from the District Departments of Transportation (DDOT) and Environment (DDOE) to replace the last of approximately 1,360 alleyway lights with new energy-efficient light-emitting diode (LED) lamps.
On July 14, 2012, Department of Energy (DOE) standards covering many popular incandescent reflector lamps will take effect, eliminating a majority of lamps from the market in favor of more efficient, higher cost alternatives.
As an estimated 5-million-piece market valued at nearly $1 billion in U.S. sales, recessed lighting has been a familiar go-to configuration within millions of professional and residential lighting applications for decades.
Outdoor Commercial lighting has changed significantly since electricity began to power it in the early 1900s. However, the advent and emergence of light-emitting diode (LED) technology with its efficiency and potential for new construction and retrofit projects would have astounded even Edison.
Declared to be revolutionary by many industry participants, solid-state-lighting (SSL) is playing a larger role in today’s construction market. Light-emitting diodes (LEDs), in particular, seem to progress month to month. However, actually using LEDs presents a challenge.
By Oct. 18, 2013, all states in the United States must put in place a commercial building energy code at least as stringent as the ASHRAE/IES 90.1 2010 energy standard, according to a Department of Energy (DOE) ruling on Oct. 19, 2011.
The Model Lighting Ordinance (MLO), produced jointly by the Illuminating Engineering Society (IES) and the International Dark-Sky Association (IDA), provides a template for municipalities seeking to develop standards for responsible outdoor lighting.
While experimenting with high-frequency current, inventor Nikola Tesla developed an electrodeless lamp, but the concept remained largely unexplored for the next century (except as a novelty lamp in the 1980s).
By now, the electrical industry is well aware that national energy standards have eliminated the manufacture and import of fluorescent magnetic ballasts for 4- and 8-foot standard and energy-saving T12 lamps, with few exceptions.
Common household lamps (light bulbs) now carry uniform labeling to facilitate educated decisions focusing on light output and energy costs, not watts, helping consumers transition to more efficient lamp types. People typically purchase traditional incandescent lamps based on wattage.
“The lights, they are a changing,” to tweak a line from Bob Dylan. Current lighting trends, which are driven by the call for energy efficiency and advances in technology, are signs of an industry in flux.
Energy codes, green building projects, user interest in flexibility and other market forces are driving demand for lighting solutions, including high-intensity discharge (HID) lighting systems, such as high-pressure sodium and metal halide.
Doing more for less is a workplace mantra these days. It applies to the work force and the energy usage of the building that houses it. Smart lighting strategies are playing a central and growing role in this confluence of productivity.
