Shadow-Caster Underwater Lighting – Light Up the Night
 

Shadow-Caster® has a full range of underwater lighting available to meet your unique needs. We have you covered with a full line of sizes and features designed to match boats of all sizes. From smaller boats to large yachts, we have you covered. Shadow-Caster has built its reputation on producing the brightest underwater lighting solutions with the finest quality available on the market.

High Quality, High Intensity Underwater Lighting For All Marine Vessels

High Intensity

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 40,000 hours).

 

Robust Design

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.

 

Surface Mounted

Our lighting solutions feature a low profile design that requires no alteration to the main hull.

 

 

Wide Input Voltage Range

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.

 

Thermal Protection

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 Marine Lighting?

 

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 coverage.

 

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 wanted.
  • Bimini Blue – This is our most popular color and is very popular with the offshore fishing crowd. It is an intense and vivid blue.
  • Ultra-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.

 

What is an LED?

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 applications.

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 high-intensity light.

 

 


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 Lighting?

Shadow-Caster 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.
