Electrical Industry Articles and Stories

It truly amazes me how LEDs have transformed the lighting industry in just a decade. In 2012, manufacturers introduced the first bulbs to match the output of a standard 60W incandescent. They weren’t dimmable and could cost $25 or more. Fast forward to 2023, and LEDs now dominate the lighting market, and inexpensive replacement lamps can cost less than $5 and last 10-20 years.

Electrical contracting is, by its nature, a bespoke profession – that is, every installation features its own unique design quirks requiring customization. At the same time, though, contractors also now are often dealing with the need to do more with fewer workers. As a result, prefabrication is becoming a bigger part of many companies’ operations.

Alternative energy sources— green, clean solar and wind power—certainly get a lot of “air time” of late. (Pun intended.)

Of course, water power has been around a long time. And still is for power generation on a large scale. But it’s not so convenient for single user electrical supply, or even most municipalities.

Looking through a manufacturer’s online enclosure catalog recently, I came across a term I hadn’t heard before. Now, I’m not a contractor, so I likely haven’t seen as many of these listings as you might have. But I am a journalist who has covered the construction industry for several decades, and the term “mild steel” stuck out to me when it showed up as a material option for the maker’s broad range of enclosure offerings.

Earlier this year at the Light + Building 2018 trade show in Frankfurt, Germany, Philips Lighting announced a string of new initiatives aimed at the transition to more LED lamps as well as the inclusion of LEDs into the “Internet of Things” (IoT) in homes and buildings worldwide.

First the company announced IoT platform called Interact, designed to handle data collected from connected light points, sensors, devices and systems.

Lighting automation has bells and whistles, but a lighting contactor is necessary to switch the actual lighting circuits. Properly selecting lighting contactors can save installation and maintenance costs. What are some of the important considerations in addition to the correct voltage and current?
