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).

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.
