fit might benefit from creating a space to try out various lamps,
fixtures and layout designs.
“That owner may be considering several buildings or mul-
tiple floors or campuses,” Zelinsky said. “They may be eyeing
control systems as well.”
Moeller said LED lighting projects that include controls
have risen by as much as 40 percent. Consequently, demos to
confirm controls’ performance are becoming more common
and might require a more sophisticated demo.
“A mockup space can make a difference in smart planning and installation for the EC, distributor, manufacturer
and owner,” Zelinsky said. “It also allows you to show a ‘
good-better-best’ scenario in terms of product and lighting strategy.”
While demonstrations can’t effectively reveal LED end-of-life—an instructive graph is the better visual—they can show
“Color rendering is one immediate feature you can see in
In the business of providing demos
an LED lighting demo,” Moeller said. “Beam focus is another,
such as adjusting light cut-off in a parking lot when demoing
LED outdoor lamps. We just won a job with a well-known
manufacturer who was able to beat their competitor through
demonstrating their product’s higher performance in terms of
light output and controllability. In fact, fewer fixtures would
be needed. The customer was not only convinced, but they
purchased what was the more expensive fixture due to better
“When engaged in an LED lighting retrofit or other instal-
lation, demos are dependent on your relationship with the
customer,” Zelinsky said. “The customer might ask the manu-
facturer to get a demo going. Maybe the distributor suggests it.
Maybe you. Either way, the demo is most successful and fruitful
when all parties work together.”
Rensselaer Polytechnic Institute (RPI) is a private research university with three campuses, with the central campus is in Troy,
N. Y. It is home to the Lighting Research Center (LRC), a leader
in lighting research and education. Its Demonstration and
Evaluation of Lighting Technologies and Applications (DELTA)
program is committed to finding energy-efficient lighting solutions. LEDs and controls are often prominent in the program.
“Some clients are seeking verification of manufacturers’
claims,” said Jennifer Brons, director of design demonstrations and adjunct assistant professor, LRC. “Other demos
might discover how to best light, say, a high-rise office with
LED, yet others might focus on the operation and performance
of a control system.”
Brons said demos are valuable when working with a technology that has hard-to-predict features.
“For example, while light levels are easy to capture with
engineering tools, occupant influence, especially with controls
and lighting use, is unpredictable,” she said.
Having a discussion with the facility owners will help focus
the demo and determine objectives.
“If it’s a retrofit demo, is [the goal] to maintain current
light levels, increase them or lower them?” Brons asked. “Will
