central frontal part of it. However,
the back burn, and to guarantee best
performance for the longest duration, it
must touch an aluminium heat-sink. And
then it must be connected with the precise
voltage supply to avoid power swings,” he
says.
That aside, the most important
elements to be taken into consideration
are lumen/watt and CRI index. “The
higher that is (90 being the benchmark),
the closer it gets to natural light,”
he says. This, he adds, relies on
expertise with digital electronic
domotics to best manage
capability of LEDs to change
from red through to green, blue
and white - and also the colour
temperatures of the latter,
through warm to cold white.
PRODUCT
INNOVATION
“Technological
evolution is always
alluring and
challenging,” Palagi
observes. “We are very
well equipped, but
if I need to identify
a problem, this
might be that every
four or five months
a new LED with
greater brightness is
launched, and this
means we need to
change data sheets
and catalogues more
often!”
Not all LEDs are
of the same high
standard, he states.
Indeed, “the market is
now full of products
of low quality,” he
cautions. To guarantee
quality, Palagi Marine
Lighting, he says,
always uses the “top brands such as
Citizen and Lumiled (Philips).
Unlike long-established Palagi Marine
Lighting, compatriot marine equipment
manufacturing company Quick Srl is
relative newcomer to the marine lighting
sector, having added this speciality to its
portfolio of boat equipment including
windlasses, bow thrusters, battery
chargers and water heaters in 2007.
Even so, Quick Marine Lighting’s
business has grown rapidly and Lorenzo
Cesari, area sales
manager, claims its lights
are sold to all major
boatbuilders worldwide.
Quick offers a
full range of LED
boat interior and
exterior lighting
products as well
as underwater
luminaries. It
still offers halogen products but,
Cesari notes that 100% of new
projects are LED.
HALOGEN VS LED
Cesari believes that
such is the rate of
growth in the marine
lighting sector that
there’s room for
competition. “The
new challenge for LED
lighting manufacturers
is to improve the
efficiency Watt/
lumens and the colour
rendering index,” he
says adding that boat
owners just see benefits
when they switch the
lighting system from
halogen to LED. “All
shipyards have already
understood this benefit
a long time ago and,
in fact, all new boat
projects are designed
with LED lighting,” he
says.
Looking ahead,
Cesari expects the
next major step in LED light technology
will be “O-LED applications”, where the
metallic coatings that produce the colour
variations of today’s LEDs will be replaced
by organic carbon compounds.
The case for the wholesale adoption
of LED technology, for marine lighting
appears overwhelming, but there are
still those in the industry who believe
that there are still questions about its
seemingly universal benefits that need to
be asked.
Peter Urquhart,
managing director
and lighting designer
of UK company
Underwater Lights
Ltd, is one who makes
a case for halogen
while acknowledging
that LED technology
has been progressing
rapidly.
With halogen, he says, “you can
reliably change them and not see any
difference, but LED lamp manufactures
change output and colour rendering
specification so quickly, so when a lamp
change is made it may not match the
existing one”.
He adds that for interior lighting of
cabin and lounge areas, where interior
designers have spent considerable time to
create something special, LED lights can
ruin the look. “Considering the cost to
design and build these areas, the halogen
is the safest option,” he says, adding
“Halogen for atmosphere and LED for
cleaning.”
At present, Urquhart sees some
mismatches between LEDs and their
drivers and control equipment. “Some do
and some do not,” says. “There’s too much
changing.” However, he points out, “the
companies in the LED market are getting
together to form a statutory standard
that should make life easier for the
designer and installers to make a correct
installation or project.” That, he says,
leaves the question how much technology
is required to dim and switch off and on
a light and how much will it cost? “The
companies that get this correct will be the
ones that remain
in business,” he says.”

the yachting industry since mid 1980s
