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. 

Over the last seven years, the LED Streetlight Replacement Program in Los Angeles has swapped more than 80 percent of the city’s 215,000 streetlight fixtures with LED units. To date, energy usage has lowered by 63 percent, saving the city approximately $9 million per year in energy costs.

While more cities and towns are making the move to LED streetlights, Anchorage, Alaska, is going even further.

Knowing how light plays and today’s LED capabilities helped designers and contractors achieve a stand-alone space, the Blossom Cocktail lounge at the MGM National Harbor casino.

From high-definition panels to vibrant pinpoint light, from deep, true color to interactivity and animation, LED lighting is becoming the go-to option to create theatrics, mood and spectacle.

Milestones in January and February raised the bar on energy efficiency in the lighting industry. In January, Energy Star Lamps V2.0 took effect, and it was predicted to significantly influence lamps promoted by utility lighting rebate programs.

Read the Label

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.
