When Sentry Equipment Corporation,
the leading supplier of sampling components and systems, decided
to build a new facility, a major concern was energy-efficiency.
The company went to great lengths choosing everything from window
glass to office ceiling materials to create an energy-efficient
environment. Naturally, they chose LED technology for most of their
The building’s original lighting design indicated
that the company’s fixtures would require about 75 kW. The company
reduced their actual lighting load, however, to only about 30 kW
through effective use of daylight and high-efficiency artificial
lighting, mainly LED technology.
Sentry estimates the cost for the
new lighting technology has an approximate 1.3-year payback. They
also project their annual lighting energy costs to be more than
$13,000 less than estimated in the original lighting design.
all of Sentry’s lighting comes from LEDs. They use some fluorescent
lighting. However, LED lighting provides the
greatest energy savings. Where the company installed LED lighting,
they reduced energy consumption from 14.6 kW in the original
plan to an actual consumption of only 3.6 kW. The company’s LED
lighting also reduced overall energy consumption since they have
a power factor near 90%, making it easier for the power company
to provide the energy. Sentry also likes the 50,000-hour life
expectancy of LEDs and the absence of hazardous materials.
all of Sentry’s exterior lighting, except their flagpole, uses
LED technology. Inside the building, all decorative,
conference-room dimmable cans, restroom, and aisle lighting use
LEDs as well.
Since experiencing the benefits of LED lighting,
Sentry has decided that LEDs will be the first choice for all their
future lighting installations.
