24/7 Operation. Many factories
operate 24 hours per day, from five to
seven days per week. LED lighting can
save time and money on maintenance
over fluorescent systems. For example,
on a 30,000-hour-rated fluorescent
system, group relamping might be performed on a two-year cycle. LED lighting
with a rated life of 50,000 hours requires maintenance one-third as often.
Cold Storage. Refrigerated manufacturing plants or warehouses represent
an excellent opportunity for LED. HID
systems normally are used in these
spaces because the low temperatures
have an adverse effect on the performance of fluorescent lighting systems;
however, while not affected by the low
temperatures, HID lighting adds significant thermal load, which has to be
removed to maintain the low temperatures. In typical refrigerated warehouses, if you save $1 in electrical costs
from LED’s lower wattage consumption,
you’ll save another $0.50 in reduced
LEED® Certification. Companies
looking to achieve Leadership in Environmental and Energy Design (LEED)
certification for their plants or warehouses may find merit in the points given for the energy reductions possible
by installing LED lighting.

most all applications.
Wide to Narrow Beam. There are
all sorts of LED options available, from
spot (narrow beam angle) to flood (wide
beam angle), that make them fit all
Constrained Spaces. Compact design allows them to be engineered for
tight-fitting or narrow spaces, which is
not possible with other light sources.
LEDs can fit into the smallest machines
or light the largest areas with great performance.
Vibration Resistance. In addition,
LED’s resistance to vibration makes it
a superior light source in rugged environments.
This lighting fixture example is an
alternative to a 400-W metal halide or 6-lamp
T5HO fluorescent high-bay and uses 35 to 50 percent less energy and has a longer life.
This fixture is typically used for mounting heights of 20 to 40 feet. Photo courtesy of

Temperature-tolerant. LED luminaires are available for the various ambient temperatures expected in manufacturing environments and offer different
degrees of protection against contaminants (IP ratings). It is up to the user to
select a luminaire that meets his lighting and environmental requirements.
High-energy-cost Geographic Regions. Manufacturing facilities that best benefit
from LED high-bays include those located in areas of the country that are
prone to high energy costs.
Hard-to-Reach Spaces. The lights are
applicable for facilities that accrue significant maintenance costs while servicing lights (requiring scissor lifts, bucket
trucks, and teams of electricians).
Hazardous Locations. Facilities that
require hazardous (classified) location
ratings on their light fixtures, where
safety is their main concern, can ben-
efit from improved quality of light and
peace of mind that the lights will func-
tion in these rugged environments for a
very long time.
