called LM-80. For good or bad,
this benchmark figure was
hastily adopted by luminaire
manufactures without regard
to other components and how
and where the fixture would
be used. Chevalier believes
that when making
longevity claims, LED
light manufacturers
“should take into
account the entire
fixture assembly,
not just the
LEDs. Long life
assertions need
to be credible and
backed up with
solid manufacturer
warranties”.


ENDLESS APPLICATIONS
John Kujawa, president and
founder of US marine lighting
company Lumitec, also questions
the credibility of the 50,000-hour service-
life claim. His company, which has been
developing, testing and manufacturing
lighting for marine and other extreme
environments since 2006 in Delray Beach,
Florida, remains
fully dedicated to
LED technology as
the replacement
for conventional
lighting
technologies and
also as a means of
enabling designers
to create new
aesthetic effects
with lighting which were not possible
before.
In the general rush to LED in the
marine lighting sector, Kujawa says:
“We definitely expect there to be a
bit of a shake-out among suppliers,“
observing that customers are growing
more sophisticated and less tolerant of
overstated claims, inferior technologies,
and less-than-impeccable reliability.
“There have been a lot of newcomers
to the (marine LED lighting) space and


while some will thrive, many
at this point seem to be too far
behind the technology curve to be
viable,” he says.
Kujawa foresees a period
of consolidation in the marine
lighting, with fewer but larger and
stronger companies emerging.
Having spent much of his career in
Silicon Valley, he observes that
as the segment becomes
more mature and
the products more
sophisticated, the
need for technical
knowledge and
sophisticated
equipment become a
barrier to entry. “I am
confident that many of
the newcomers to the
space are still in the
dangerous ‘startup’
period, and that
period is becoming longer
and more hazardous for
newcomers. As in the Darwinian
sense, it’s the fittest that will
survive.”
For those companies that can
stay the pace, Kujawa believes
that LED technology
will continue to offer
the best business
opportunities.
What’s more, as a
relatively new field,
the possibilities
for innovation in
marine lighting are
seemingly endless.
To some extent the
only solution for the consumer is
to see these devices for what they
are: sophisticated electronics not
unlike a chart plotter or a smart-
phone. But forward-thinking
manufacturers can help as well.
In Europe, Foresti & Suardi,
Cantalupi Lghting and Palagi
Marine Lights, are also strong
players in the marine lighting
sector.
Alessandro Palagi, Palagi

Marine Lights CEO, reflects that when
LED first appeared “many of our
competitors put them immediately on the
market. We didn’t do that, as they didn’t
provide the same light as an halogen
20watt, and light quality was not good at
all.”
This wait-and-see approach giving
time for the technology to mature has
paid off, he says, “with great growth rates
as we have now achieved an excellent
quality level of LED. It doesn’t make
sense to go back to halogen lights, even
when disregarding the energy savings
and 30,000/40,000 hours of life for LED
against a maximum 1,000/2,000 for
halogens. We are now lighting a boat with
4 Watt LED spotlights, and we use to do it
with 20 Watt halogens!”

BEST RESULTS
The longevity of LED lights, however, is
a great attraction, given that previously
with conventional technologies, “it could
be necessary to change up to 300 lamps
on a 45m yacht”, says Palagi.
But, like others in this review, he
points out that there are major
differences with LED technology
that need to be appreciated in
order to achieve the best results.
He mentions, for example, the
need for heat dissipation. “It’s
true that LEDs are famous for
not producing heat, but although
that’s true if you touch the
