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. 

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.

Crops, of course, have always relied on three things from nature: soil, water, and sunlight. If executives at AeroFarms have their way, though, the future of crop growing will be mesh cloth, small amounts of water, and LED lights.

Out With The Old: Replacing LED Drivers


The majority of LED lighting products use an electronic driver that functions similarly to a fluorescent ballast. The driver converts incoming alternating current (AC) to direct current (DC) and drives this current to the LEDs.

The Shape of Things to Come: Trends in 
Luminaire Design

For a long time, the lighting industry relied on conventional, legacy light sources and traditional designs. Recent advancements in LED technology, however, have changed the face of the industry in terms of the form and function of luminaires.

Holding Their Own: Linear Fluorescents Adapt to Today's Lighting Needs

LED marketing can give the impression that digital lighting has left other lighting sources in the dust. Not quite. Linear fluorescents are a case in point. While LEDs have their own merits in light quality, energy draw and controllability, so do many of today’s fluorescents.
