Lighting

 

 

Lighting and controls is a huge, constantly changing, dynamic market. The ELECTRICAL CONTRACTOR lighting editorial listed below keeps current on technological innovations from LEDs, controls, and design to innovations in efficiency by traditional lighting formats. 

Human perception of colors in their environment is dependent on light. As electric light sources have varying spectral emissions, the electrical industry relies on metrics to report, evaluate and predict how colors will appear under different light sources.

According to the U.S. Department of Energy (DOE), more than 360 million troffers (named for a cross between trough and coffer) provide general lighting in commercial building interiors.

An interesting phrase comes up frequently in the rapidly evolving streetlight market: “real estate.” Most of us see a streetlight as a utilitarian lighting fixture, but manufacturers, utilities and city managers see a business opportunity enabled by a vast network of powered, connected devices.

Lighting controls save energy by turning off or reducing lighting when it's not needed. The smarter the control and the more flexible the light source, the greater precision in delivering maximum energy savings. Because LED lighting is instant-on and easily controllable, outdoor lighting control now offers higher energy cost savings through flexibility.

According to the U.S. Department of Energy (DOE), about 160 million lamps operated in the building exterior, parking area and roadway lighting markets in 2010. Building exterior made up 39 percent of these lamps, parking 33 percent and roadway 28 percent.

The Dawn Of Commissioning

When commissioning a high-performance building, one element of lighting control is sometimes left out: the daylight harvesting system. It’s assumed such systems will work right out of the box after some simple calibration. Working is one thing, but working optimally is another.

The Faceted Equation of ROI And SSL

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.

Led Down a New Path by LEDs

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.
