feature | reliable strategies
to collect data theoretically about anything
that is measurable, which would be fed to a
central point for analysis using third-party
software.
 Indoor positioning. RFID (radiofrequency identification) tags on items such
as warehouse forklifts can transmit signals
through local light fixtures to apps on
mobile devices, which allows easy tracking
of equipment.
Overall, installing lighting controls as part
of an LED upgrade provides a path to maximizing energy cost savings and leveraging
the lighting system to generate actionable
data with a substantial potential impact on
operations.

MAKING IT WORK

Beyond associated energy and maintenance cost savings, upgrading a facility's lighting can potentially
offer a better quality of light in the operation.

central command station using radio waves.
This integrated approach to lighting control
provides remarkable benefits:
 Centralized control. The operator is put
in full command of the facility's lighting
system. Connecting light fixtures in a wireless network enables easy configuration of
settings and control zones and reconfiguration as space needs change. Commissioning
(startup and testing) is simplified as it is
done remotely.
 Building-system integration. Unifying
all control points into a single system permits connection to other building systems
such as the energy-management system for
increased energy savings and capabilities.
 Demand response. Centralizing control
of switching and dimming enables lighting
to participate in a utility-demand-response

program, if available. In such programs, the
utility offers favorable rates to large industrial customers in exchange for agreeing to
reduce electrical loads during emergency
grid events.
 Internet of Things (IoT). Integrating
control points in a network permits data to
be sent to a central server or a cloud system
for retrieval and analysis by vendor software
or third-party apps. This basic capability is
another revolution in the making that will
transform plant buildings.
Basic capabilities include energy measurement, which can be used to optimize energy
efficiency, and power monitoring, which can
be used for lighting maintenance. Additional
capabilities can be gained by using occupancy data. From this starting point, additional
sensors can be installed with the light fixtures

The key to gaining the benefits of LED
lighting is to prioritize quality of light and be
discerning about product quality. First, be
aware that today's marketplace offers a wide
range of product quality, with differences that
can have a big effect on performance.
For example, LEDs emit little radiated heat, but generate heat internally. The
fixture must be able to manage this heat or
risk shorter product life with failure modes
expressed as low light output, color shift,
and driver (a device that regulates the LEDs'
operation similar to a ballast) failure. The
driver should be of high quality, feature all
the required ratings for the application, and
be serviceable. The optics should deliver light
where it is needed and without direct glare.
It's important for industrial facilities to
work with suppliers who can deliver rugged
products that perform reliably in a wide
range of demanding environments, and with
consultants/contractors who are comfortable
and familiar with those technologies. EP
