SAFETY
"It's absolutely amazing, like a
night and day difference," says Ryan
Herbstreith, facility services manager
at Duncan. "The guys love it, and they
want to know when we're going to
replace the lights in Hangar 3, and all
the other hangars."
At the Anglo-Normandy Aero
Engineering hangar in the UK, the
company upgraded its antiquated 400W
metal halides to 250W LED high bays
and saw lux levels nearly triple, from 140
to 400 at work level.
"The quality of light exceeds my
expectations," said projects and facilities
manager Chris Roussel. He also notes
the improved visibility creates a better
working environment for staff.

Industrial LED technology produces
a crisp, bright light that mimics natural
daylight at 80+ CRI, depending on the
manufacturer, model and desired color.
This makes colors appear naturally and
easier to distinguish, allowing workers
to clearly differentiate wiring, warning
placards and fluids.

LED eliminates toxic
materials
Convent iona l l ight ing contains
toxic chemicals that can put exposed
individuals at serious risk. A single metal
halide fixture contains enough mercury
to poison an entire classroom full of
children. A single broken bulb could
affect dozens of workers with immediate
symptoms, and for maintenance crews,

Color accuracy improves
visual acuity
Color rendering, measured on the
Color Rendering Index (CRI), can
also be a significant safety concern in
aviation facilities. The CRI of metal
halide fixtures is around 65-70 on a
scale of 100, where 100 is equivalent to
natural daylight. This unnatural orange
glow makes it extremely difficult to
distinguish colors.
For electricians who rely on the
color-coding of wiring to work accurately
and safely, the inability to distinguish a
blue wire from a red one could result in
a very serious injury, or worse. It's also
a problem for color-matching paint and
other aesthetic or quality assurance work.

long-term exposure can cause chronic
illness. Fluorescents and other fixtures
can also contain mercury, phosphorous
and other rare earth minerals that are
harmful when inhaled.
Industrial LED fixtures contain no
hazardous materials, which means zero
risk of exposure for workers. It also
means aviation facilities can eliminate
the cost of hazardous material disposal
and achieve sustainability goals to operate
with minimal environmental impact.

Maximum efficiency
minimizes costs
In addition to making for a safer, more
vibrant work environment, LED lighting
technology can also substantially reduce

operating costs and improve overall
facility efficiency.
Aside from being the most energy
efficient lighting solution on the market-
Anglo-Normandy saw its power draw
drop from 3.37W/square meter to
3.96W and Duncan cut its energy use
by 44 percent per fixture-they're also
virtually maintenance free. With some
fixture models now carrying a 10-year
warranty, aviation companies can
dramatically reduce their maintenance
costs, directing those resources into more
useful, strategic efforts besides changing
lightbulbs.
For even greater efficiency, LEDs
are the only industrial lighting source
that's fully compatible with the use of
occupancy sensors, dimmers, timers
and other smart controls. This allows
facilities to reduce fixture burn time
by actually turning off the lights when
not in use. At Duncan Aviation's aircraft
paint facility, the company used a 1-10V
dimming cable wired into the lighting
control at the panel box, married to a
Rockwell PLC located outside the Class
I Div 1 environment. This allows the
lights to be dimmed as much as desired
when they're not needed, saving both
electricity and money. That's not possible
with conventional fixtures like metal
halides, which can take up to 20 minutes
to warm up, forcing facilities to leave
them burning 16/7 or 24/7, wasting
energy and money.

Superior technology,
outstanding facility
performance
Industrial LED technology is an
outstanding choice for maximizing
aviation business performance. LED
f ixtures are well-suited for high
mounting heights and effectively lighting
large, voluminous spaces with pleasing,
natural light. They're also a sustainable
and energy-eff icient choice which
contributes significantly to personnel
safety with superior visibility that reduces
the risk of accidents and injury.
And, with a combined energy,
maintenance and operational cost savings,
facilities like Duncan Aviation can see
a payback on their investment in LED
lighting in as little as four years, for
savings that go straight to the bottom
line for years to come. 
