New lighting technologies such as LED and fluorescent light
sources, lighting controls, and daylighting create excellent opportunities for
energy savings. As the market shifts
toward greater energy efficiency and intelligence in systems, luminaires
(a.k.a. light fixtures) are the first thing to consider when planning your
In the lighting world, luminaires are the complete
package. Luminaires are electrical
devices that integrate everything from the power supply and connection to the
light source and optical system.
Examples of luminaires include your everyday desk light, industrial
warehouse fixtures, and outdoor street lighting; each luminaire is designed to
deliver light for specific tasks and applications.
As light sources have evolved from incandescent to
fluorescent and now LED technology, luminaires have followed suit. Advanced techniques for heat dissipation,
optical lenses, and intelligent controls are being integrated into today’s luminaires
to improve light quality and system integration. To maximize the energy savings of any whole
building strategy, luminaires should be selected in concert with lamps,
ballasts/drivers, and lighting controls.
New, more energy efficient luminaires can offer a higher
lumen output, reducing the number of fixtures required to illuminate a space
while maintaining the same lumen levels.
ROI for luminaire retrofits in commercial and industrial applications
vary based on application and local energy prices; when combined with a whole
building strategy, ROI is typically 3-5 years.
Better quality of light and a better bottom line, that’s a pretty tough
combination to beat.
