LED Underwater Boat Lights

Underwater lights open up a whole new world most boaters never experience.

LED Underwater Boat Lights

They’ll remember this. The nights on your boat watching the fish play in the lights, the overnight fishing trips, the couples nights spent talking and laughing until well after midnight, the romantic evenings under the stars for just the two of you. Memories are what boating is all about and you’ll making plenty with Shadow-Caster underwater LED lights on your boat.

Some people say that underwater lights are only good for showing off. You know it’s more than that. Sure, they turn heads at the restaurant and at the marina. But what they really do is open up a whole new world of boating. They open up the night!

Designed to Last

Shadow-Caster SCM series lights are designed to survive the harshest conditions mother nature, and your boat can throw at them. First, a super tough polycarbonate lens, 10 times more impact-resistant than glass, protects the LEDs from impacts by floating debris. Next, the 316 stainless steel housing and backing plate keep your lights looking new. 316 stainless is the most corrosion resistant steel known to man greatly resisting staining and pitting even in saltwater. But there’s more.

316 stainless steel is also excellent at transferring heat from the LEDs to the water. Heat is a LEDs biggest enemy. As the LEDs produce light they also produce a small amount of heat. If the heat is allowed to build up, the LEDs start to break down and eventually stop working. The 316 stainless steel body of Shadow-Caster SCM series lights move this heat away from the LEDs and into the water much more efficiently than our competitor’s plastic body lights.

Three Times The Protection

Built into every Shadow-Caster underwater light are three levels of protection.

Thermal Protection circuits monitor the LEDs for overheating. This circuit will cut back on the power or even shut the light off, to protect it from damage.

Surge Protection circuits monitor the voltage coming into the light and temporarily stops power flow when a high voltage spike occurs. It only takes a few of these high voltage spikes to destroy LED chips if they are left unprotected.

Every time a piece of electrical equipment on a boat is turned on or off there is the potential to send a high voltage spike through your boats electrical system. Electric motors, windlass, bow thrusters, winches, starting motor…, are the biggest offenders. But even flushing the head or turning on a radio can send one of these spikes through your system.

Other brands of underwater lights use inexpensive forms of surge protection or give you no surge protection at all. Shadow-Caster uses only the highest quality circuits to protect your lights from the devastating effects of these high voltage spikes.

Reverse Polarity Protection. Polarity is the direction power flows through a circuit such as an LED light. On incandescent lights, polarity did not matter. As long as power flowed through the light it lit up. But with LED lights it does matter. Sending power in the wrong direction will damage the LED chips. Many other brands use inexpensive circuits or give no protection at all leaving their lights exposed to damage. Shadow-Caster protects all of their underwater lights by using only the best available circuits to stop power from flowing in the wrong direction.

Great Looks

One of the nicest compliments I hear about Shadow-Caster SCM series lights is how good they look. The oval shape of the light is stylish and spreads the LEDs across a wider area. Spreading the LEDs over a wider area like this helps to flood the water with light instead of creating a spotlight effect like other brands.

Shadow-Caster LED underwater lights are made in 5 beautiful colors, Bimini Blue, Ultra Blue, Aqua Green, Great White, and Cool Red. Choose the color that best matches your boat style or one that best suits how you use your boat. There is even a color changing model that gives you four of our most popular colors in one light. With the flip of a switch, you can change color or make the lights fade, flash, or strobe.

What Size Do You Need?

There are three different sizes of lights to choose from in the Shadow-Caster SCM series of lights. You also have the choice of a single light color or color changing model in their largest light the SCM-10/ SCM-CC.

Boats come in many different sizes and bodies of water can be very clear, very dirty, or anywhere in between. The light that is best for your boat will depend on how big the boat is, how clean the water you boat in is, how much light you want, and your budget. With Shadow-Caster, you can always add more lights or even different sized lights at a later date.
