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. 

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.


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.

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.

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