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.
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.
Lighting currently represents about 17.5 percent of all global electricity consumption, according to the EnergyWatch newsletter from Attardi Marketing. The United States alone accounts for approximately 20 percent of this amount at an annual cost of more than $40 billion.
If the nation’s rising unemployment, flagging construction, and global debt crisis didn’t give electrical contractors enough cause for concern, they have recently been grappling with another business woe—significant price increases on some of the market’s most popular energy-efficient fluorescent la
Driven by commercial building energy codes, green building projects and owner demands for flexibility and lighting energy savings, lighting controls increasingly are being specified and specified systems are becoming increasingly sophisticated.
