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 artificial lighting.

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.

Not 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.

Today, 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.
