It is the driving force behind our history of innovation that continues to drive the company forward. Indeed, many technologies that OceanLED has pioneered are still found in our lights today, some of which remain as milestones in the history of marine lighting.

With a heritage in marine lighting dating back to 1991, we not only understand what the marine environment demands in terms of performance and quality, but we understand the importance of creating unique solutions for the Marine industry.

What are the most important factors when choosing an underwater light?

The most important factor should always be what the light looks like underwater and whether the light can achieve your desired effect and control.

OceanLED's optics are bespoke and are designed to direct light to achieve more penetration through the water. OceanLED offers lights with a variety of beam shapes and surface angles, allowing our customers to create the lighting they want.

OceanLED lights are designed to use less power, maintain much longer life spans, and with far better color retention and clarity.

Can I run with my underwater lights on?

Absolutely, LEDs are a solid-state light source and therefore are not vulnerable to vibration-related failures. OceanLED lights are fitted with thermal protection, so if the light overheats it will dim or turn itself off as a precaution until the temperature has reduced to a safe level for the LEDs to be in use.

What is the best color for underwater lighting?

Blue and green light has shorter wavelengths than white light and can penetrate through the water more efficiently, giving a better lighting effect. The human eye is more sensitive to shades of blue and green, so these colors will make your lighting display stand out.

However, if you do your boating in crystal clear waters we recommend white, as this enhances the natural beauty. OceanLED's ultra-white LEDs are whiter than any other underwater light on the market so when you want a white light, at 6500k color temperature providing a stunning display.

Choose OceanLED Colours LED lights for optimum choice and flexibility.

Can I use my SHADOW-CASTER marine lighting out of water?

SHADOW-CASTER underwater lights do get warm and rely on water immersion to stay cool. However, if your lights come out of the water when running on a plane, the small amount of splash they receive is enough to keep them cool. SHADOW-CASTER™ underwater lights utilize a thermal protection circuit and will reduce their output so that they never get hotter than a hot cup of coffee. This feature makes SHADOW-CASTER™ underwater lights worry-free and prevents them from hurting you or damaging your boat.

How do I clean my underwater light lenses?

All OceanLED lights are treated with the unique Tritonium coating. This forms a non-stick layer making it virtually impossible for marine growth to stick to the lens. If you find it does, however, it is very easy to clean. When in the water a soft bristle brush should do the trick. When out of the water then make sure the lens is soaked with water and then use an ice scraper or something similar.

What is the Shadow-Caster advantage?

How many SHADOW-CASTER™ lights do I need?

The appropriate number of lights to use is a personal choice and depends on desired brightness and budget. There are no hard and fast rules to apply here. SHADOW-CASTER™ underwater LED lights have a very low profile and produce a wide beam pattern. Generally, Shadow-Caster recommends 2 lights mounted on opposite sides of the transom for boats up to 21 ft in length. As the size of the boat and beam increase, it is recommended that more lights be installed for continuous coverage. Usually, lights are added 1 for every additional 1meter/3ft of transom width over 3meters/9ft. They can also be installed on the sides of boats for users that want extra light coverage.

What is Shadow-NET Technology?

Shadow-NET is a proprietary technology that is integrated into SHADOW-CASTER™ lighting products. It is based on a CAN bus. CAN (Control Area Network) is very robust and has been used extensively in the automotive industry for digital communications. In the marine industry it is the basis for NMEA 2000 networks that are used to communicate RPM, GPS, fuel gauge and other critical information between marine helms and motors, and other marine devices. Shadow-Caster’s Shadow-NET 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 Shadow-NET™ enabled lighting products. Through Shadow-NET™ enabled devices it is possible to integrate with other communication protocols, such as, ethernet and WiFi. Please contact a Shadow-Caster representative for more details.
