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. 

Simply stated, the Sistine Chapel is a really big room with many remarkable paintings, but there are many stories behind the hall and its art.


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.


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. 


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.

The green design—good for the environment in that it makes buildings more sustainable—can be bad for lighting, as designers are incentivized to chase points that may require sacrifices to design. For lighting, it can be especially risky.

In part 1 of this two-part series on photosensors, I described the major characteristics of photosensors and ended with a problem: suppose we have a classroom in which we want to begin dimming the row of fluorescent lighting fixtures adjacent to a series of windows when daylight levels reach 150 pe

Daylight harvesting’s value proposition is fairly simple: as daylight levels increase in a space, electric lighting levels can be automatically reduced to maintain a target task lighting level and save energy.

Once a venerable workhorse in commercial lighting, the fluorescent magnetic T12 ballast is now considered a dinosaur. All but extinct in new construction, there are still millions of these ballasts installed in commercial buildings throughout the United States.
