FREE STANDARD SHIPPING within the United States on the S1800 B (limited time offer).

The S1800 B is a high powered blue LED boat light that features a floodlight design, illuminating a large, wide area behind your transom. We also offer the S1800 (Brilliant White) for enthusiasts looking for a different look.

Whether you're looking to attract fish or just improve the ambiance, our underwater lights represent the best value in the industry. We've been designing, assembling, distributing, and servicing our popular line of marine lighting in the United States for over five years and have built an excellent reputation for quality and service.

State-of-the-Art LED Technology

All of the Abyss Technology lighting products feature state-of-the-art light emitting diode (LED) technology. LED technology ensures longevity (over 35,000 hours of operation), safety, and efficiency.

The exceptionally low electrical power requirement of our LED technology reduces battery drainage, allowing the light to remain on for a longer period of time, even with the boat’s engines off.

The S1800 B produces a large light output despite its low profile, measuring only 1/2" thick (see Data Sheet tab for specs). To aid in its cooling while lit, we've designed it with a pass-through cooling system that allows water to surround it on 360 degrees, keeping the light cool and efficient.

Construction and Installation

The S1800 B is constructed from marine grade bronze with an impact resistant tempered glass lens. Carefully assembled and permanently sealed, our underwater lights are totally waterproof and fully submersible, suitable for both salt water and fresh water usage.

Because of its flush-mounted design, installation only requires a tiny 3/16" hole in your transom. Many competing lights require a large (several inch diameter) hole for mounting, creating potential structural strength, leakage, and other concerns.

Installation of the S1800 B is easy; simply pass the supply wire through a tiny 3/16” hole in the transom and route it to a power source. Apply marine grade sealant to the hole (as well as the mounting holes) and fasten the light to your boat using the included stainless steel screws.

Our LED boat lights are equipped with five feet of electrical wire.  The S1800 does not require an external voltage regulator.

We are an original equipment supplier to several major brand name boat builders and have built a reputation for quality, reliability, value, and excellent service.

Non-Marine Applications

Fully submersible, underwater boat lights have been popular with boaters for many years as a way to illuminate the water around their watercraft. Our LED lights are also an excellent choice for docks, ponds, fountains, or any other underwater lighting application.

Switches

We sell marine light switches that are suitable for installation with the S1800 B.  Light switches should be selected such that the maximum current rating of the switch exceeds the total current draw of the connected lights.  The S1800 B draws approximately 2 amps, so we recommend selecting a marine light switch as follows:

1 or 2 S1800 B lights: SW6 switch

3 or 4 S1800 B lights: SW10 switch

5, 6, or 7 S1800 B lights: SW15 switch

8 or more lights: additional switches required
