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.

Right now, a pack of six standard 60 watt incandescent light bulbs will cost you about $15 on Amazon. If you want something a bit more special (say bulbs connected to Thomas Edison) it’s going to cost you—a lot.

The Town of Hempstead, just east of New York City, has a population of almost 800,000, and the town's government is tasked with installing, maintaining, and replacing 50,000 street lights.

As local government and business owners look for ways to improve efficiency and reduce greenhouse-gas emissions, outdoor lighting has become one of the most practical ways for them to reach their goals.


LED streetlights have the potential to reduce energy consumption by about 50 percent compared to traditional high-pressure sodium lights. According to a U.S. Department of Energy (DOE) survey of governments and utilities, 62 percent of respondents reported using LED sources in their streetlighting.

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.

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.
