When to Upgrade to LED
LED models are increasingly common as exterior aircraft lighting
solutions. Knowing when to retrofit can be tricky.

T
o what extent have LED lighting solutions have
been embraced? What should be considered
in a cost-benefit analysis for deciding when to
upgrade older lamps to newer LED models?
Common Lighting Solutions
John Fogel, product manager at Amglo, says LED lights
are becoming increasingly common for exterior lighting.
" LED exterior lighting has become very common in commercial
and business aviation and are available for retrofit from
several suppliers, " affirmed Heads Up Technologies, which specializes
in end-to-end design, qualification, manufacturing, and
field support of both interior and exterior LED lighting systems.
Almost all new production aircraft come equipped with exterior
LED lighting systems, said Andre Hessling, principal fellow at
Collins Aerospace - Interiors.
" While there are still many legacy aircraft operating today
with xenon, halogen or fluorescent bulbs, operators are seeing

the many benefits to retrofitting existing technology with LED
lighting systems, " he pointed out. " In the majority of cases, LEDs
provide the same or improved functionality, while requiring far
less power draw and lasting as much as 100 times longer than
legacy lighting solutions. Operators see an expedited return on
their new installation, realizing that the frequency, cost, and time
spent on ongoing maintenance and replacement is much less
with LED technology. "
Areas of Impact
When analyzing if an upgrade from older lamps to LEDs is the
right decision, some main areas of impact must be considered.
" In the first place, the lifecycle costs, given that LEDs have longer
lives than legacy lighting systems and can provide a reduced direct
operating cost and higher aircraft availability after the upfront
installation costs. Then, in terms of performance, the LED lights
are more energy and thermally efficient than traditional exterior
lights, " according to Heads Up Technologies.
