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. 

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).

In the Age of Wi-Fi, even lamps have become part of the growing internet of things (IoT). According to “Navigant Research Leaderboard Report: Residential Connected Lighting,” companies that make IoT-friendly lamps are getting smarter, too, and the market is growing.

The Weak Spot

The light-emitting diode (LED) offers energy savings, lower maintenance requirements and other advantages compared to incandescent sources. However, many LED products perform poorly with existing dimmer controls.

Solid State Of Mind

Lighting plays a critical role in retail spaces. It can attract customer attention; display merchandise in a compelling way; affect customer experience; and communicate brand, quality and price point.

Energy Codes Light the Way

A large majority of commercial building energy codes in the United States are based on either the ASHRAE/IES 90.1 energy standard or the International Energy Conservation Code (IECC) model code. Both feature increasingly stringent requirements for lighting controls.

Estimating Energy Savings

As energy-saving automatic lighting controls become more popular for retrofit options in existing buildings, electrical contractors may find themselves in a position of estimating energy savings to justify owner investment.

One for the Road: Roadway Lighting

Roughly 70 million U.S. street and roadway lighting fixtures—estimated to be a $200–300 million market—represent big business for electrical contractors, especially as this application increasingly converts to light-emitting diode (LED) technology.

The Next Step In Efficient Lighting

Federal ballast energy regulations took effect Nov. 14, 2014, and they primarily affect the availability of T12 electronic, sign and residential-only ballasts.

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.
