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. 

High-intensity discharge (HID) lamps, notably metal halide and high-pressure sodium, are widely installed in industrial, retail, and other applications. In recent years, the LED revolution has produced retrofit options promising up to 50 percent energy savings and long service life.

Traditionally, commercial electrical systems are based on alternating current (AC). The utility grid delivers AC power, which the building distributes. Low-voltage devices include a rectifier that converts AC to direct current (DC), with associated electrical losses.


When attending large conventions such as Lightfair International (LFI), attendees expect to see industry experts with decades of experience. It is less expected to meet a college junior, as 2017 LFI attendees did in Philadelphia in May.

In commercial building applications, dimming either is used to support visual needs (usually in response to manual input) or to save energy (usually in response to automatic input).

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.
