High Quality, High Intensity Underwater Lighting For All Marine Vessels
Shadow-Caster underwater LED
lights are designed to deliver the most intense optical output. Our unique
design allows us to produce maximum light output and maximum LED life (over
With Shadow-Caster underwater
LED lights, there’s no additional external components to install. Just connect
the cable (submersible to 20 feet). All the necessary electronics are
integrated into the housing and resistant to vibration and the elements.
Our lighting solutions feature
a low profile design that requires no alteration to the main hull.
Shadow-Caster’s underwater LED
lights have an input range of 10 to 30 volts and work equally well on sets of
12 or 24 volts.
Our unique thermal protection
features a control system that detects internal temperature and adjusts energy
production down to avoid damage.
Surge and Polarity Protection
Our lighting systems have an
innovative protection system that automatically disconnects the input entry
when excessive voltage or reverse polarity is detected.
You Have Questions. We Have the Answers
What Would You Like to Know About Shadow-Caster
Can I use my Shadow-Caster Marine Lighting out of water? Do LEDs get hot?
Shadow-Caster underwater lights
get warm. They rely on being in an aquatic environment to stay cool. However,
if your lights come out of the water when running on plane, the small amount
of splash that they receive is enough to keep them cool. Shadow-Caster
underwater lights utilize a thermal protection roll back circuit and will
reduce their output so that they never get hotter than a hot cup of coffee.
How long can I run my Shadow-Caster lights on a standard marine battery?
A typical group D battery
stores approximately 120amp hours of power. Two SCM-10 underwater lights will
draw about 7 amps. This equates to at least 17 hours of continuous use. It is
not recommended to deplete marine batteries to less than 20% of their
available capacity, however.
How many Shadow-Caster lights do I need?
The appropriate number of
lights to use is certainly a personal choice. There are no hard and fast rules
to apply here. Generally we recommend 2 lights mounted on opposite sides of
the transom for typical applications. As the size of the boat and beam
increase, it is recommended that more lights be installed for good
coverage. Typically on boats 26 and up, we recommend at least 3 across the
transom. Shadow-Caster Underwater LED lights have a very low profile and are
typically installed on the sides of boats for users that want the extra light
What color LED lights should I install?
The appropriate color
choice of LED is ultimately a personal decision. The condition of the water
where you will be using the lights is a big factor in this decision. Many
times the decision on color is made to compliment the color of the boat. We
typically do not recommend white lights for areas where the color of the water
is dark or murky, as the white light will tend to filter through as the color
of the water.
We offer our lights in
5 different single color versions, and color changing versions.
Great White –
Is best where the water is clear and where a good view of underwater life is
Bimini Blue –
This is our most popular color and is very popular with the offshore fishing
crowd. It is an intense and vivid blue.
This shade of blue falls more towards the violet end of the spectrum than
Bimini-Blue. It is a great choice to compliment purple hulls where customers
want to really stand out from the crowd.
Aqua Green –
This color is very popular with the inshore fishing crowd.
Cool Red –
Is very intense and most popular with the “Go Fast” boating crowd. It
provides an eerie and ominous Red color under the water.
LED stands for Light
Emitting Diode. LEDs are commonly referred to as the pinnacle of modern
technology. Although LEDs have been around for years, only in the past decade
has the technology evolved enough for these small devices to be practical for
lighting applications. LEDs are semiconductor devices that are manufactured
using similar processes to those used in the production of modern computer
chips. Modern LED devices are “solid state” and grown from solid Silicon
Carbide material, allowing for huge advantages in reliability and stability.
The actual mechanism
for producing light has to do with the “PN” junction buried inside the device.
When an electron in the form of current running through the device crosses
this PN junction barrier, it moves to a lower energy state and gives off a
photon of light. A photon is the smallest basic unit of light.
The inherent efficiency of an
LED is associated with the fact that this PN junction energy relationship is
narrow enough that all of the light emitted will be centered around a specific
wavelength. In typical lighting mechanisms such as incandescent lighting,
there is a broad spectrum of light emitted, most of which is outside the
visible and usable spectrum.
What is Shadow-NET™ Technology?
Shadow-NET is a proprietary
technology that is integrated into Shadow-Caster lighting products. This
network allows us to individually address and control the color and intensity
of each Shadow-Caster Light. Physically, this connection is the Orange and
Yellow wires found in our enabled lighting products. Through Shadow-Net
enabled devices, it is possible to integrate with other communication
protocols, such as DMX, Ethernet and Wifi. Please contact a Shadow-Caster
representative for more details.
What is the advantage of an LED?
LED light bulbs are
more rugged and damage-resistant than incandescent light bulbs. An efficient
system, LED light bulbs are increasingly being used in a wide range of
LEDs offer many advantages over
traditional lighting systems. LEDs offer a longer life span, lower energy
consumption, improved robustness, smaller size, faster switching times, and
better durability and reliability. A group of LEDs is capable of producing
What is the difference between lux and lumen?
This is a question that we get
asked quite often by customers who are confused by all of the different
specifications that manufacturers offer for their products. “Lumen”, is a
measurement for the total amount of light emitted by a source. “Lux” is a
measurement for the total amount of light that is directed towards a small
area. If you focus the light from an LED into a small area, the number of
lumens will stay the same, while the “lux” will increase greatly. Our research
has shown that producing a wide beam of light performs the best for underwater
applications, and provides the maximum usable light.
What is the proper procedure for cleaning and care for Shadow-Caster Marine
underwater lights are designed to live under the water. Anyone that owns a
boat, especially boats that live in saltwater, understands what a harsh
environment this is. Combine corrosion with the fact that barnacles quickly
grow on anything left in the water, and it is easy to appreciate the
challenges involved with designing products to live in this environment.
We recommend that
lights be cleaned regularly to provide the optimum performance. When lights
are cleaned regularly by simple brushing, marine growth will be minimal. If
you are maintaining a boat that resides in the water, we can recommend some
clear coatings that will inhibit the growth and still allow light to transmit.
In the event that staining
occurs, we recommend Naval Jelly which is commonly available at your local
hardware store. Simply follow the manufactures’ recommendation. This typically
just involves applying it to affected areas and rinsing it off.
What is the Shadow-Caster Advantage?
Shadow Caster Lights® are the
most highly engineered Underwater Lighting products on the market. This fact,
combined with superior customer support, makes us the clear choice for LED
Lighting for marine applications.
