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. 

Light-emitting diode tube lights, or TLEDs, are gaining recognition of their own in residential and commercial buildings.


In October, New York Gov. Andrew Cuomo announced plans to “transform” New York City’s bridges and tunnels “for the 21st Century.” The plan has four goals: reduce congestion, combat emerging security threats, increase flood resiliency and promote energy conservation.


In its latest LED energy savings forecast, the U.S. Department of Energy (DOE) predicts LED lighting will represent 30 percent of the installed lighting base within five years and 59 percent by 2025.


Major lighting trends—including LED, intelligent lighting controls, the industrial Internet of Things (IIoT), power over ethernet (PoE), energy codes, and light and health—are creating new opportunities and challenges for electrical contractors.

Lighting Regulations

In February 2014, the U.S. Department of Energy (DOE) announced new energy-efficiency standards for ballasts sold as part of new metal-halide luminaires, which are commonly used for illumination in parking lots, roadways, warehouses, big-box retail and floodlighting. Compliance is required by Feb.

As efficacy, longevity and cost continue to improve, solid-state lighting will become increasingly prevalent. Falling costs have already placed LED solutions at a tipping point for upgrades in several applications in existing buildings, such as in this all-LED retrofit of a Walgreens in Buffalo Grove, Ill.
Lighting for Tomorrow

It’s an exciting time to be in the lighting industry. Today, lighting systems can alter spaces without physically changing them, revitalize urban areas, facilitate interaction and community, communicate information, make spaces more interactive, and affect well being.

Part Art, Part Science

Landscape lighting is one of the most artistic lighting design disciplines. Its primary purpose is ambience—to make nighttime spaces aesthetic and inviting. On a more practical level, it can extend the usable hours of a site, facilitate wayfinding, improve safety and provide a sense of security.
