BASIKER Marine LED Underwater Boat Lights BS4 BL, 3000LM — Pair with 316 Stainless Steel, 180° Wide Blue Beam

BASIKER BS4 Marine LED Underwater Boat Lights are a pair of 180° wide-angle, 3000-lumen blue LED fixtures built in 316 stainless steel with IP68 protection for durable underwater illumination.

These are purpose-made underwater lamps designed to add powerful, wide-spread blue light to transoms, swim platforms, and hulls. Each light houses 84 LEDs and operates on 10–30V DC, producing up to 3000 lumens per pair with a broad 180° beam. The construction focuses on corrosion resistance and long service life, using marine-grade 316 stainless steel, a reinforced PC housing, and an upgraded triple-seal waterproof system filled with marine glue.

How do these lights perform in salty marine environments?

The BASIKER BS4 uses 316 stainless steel and high-strength polycarbonate to resist saltwater corrosion and mechanical wear. The finish is plasma-polished for extra smoothness, which reduces salt adherence and eases cleaning. An upgraded IP68 full-fill waterproofing keeps electronics sealed even during prolonged underwater exposure.

• 316 stainless steel body resists pitting and corrosion in saltwater
• High-strength PC housing withstands impact and extrusion
• Triple waterproof system with PCB coating and filled marine glue

How difficult is installation and what wiring does it need?

Installation is straightforward for most boat owners: the lights mount on the surface with screws and connect with only two wires to your 10–30V DC system. Adding marine-grade waterproof sealant between the light flange and hull is recommended for extra protection. Always install an appropriate in-line fuse per marine electrical codes to protect the circuit.

• Surface-mount design with matching screws and stickers included
• Simple two-wire connection to 10–30V DC systems
• Recommend added marine glue seal and inline fuse for safety

What kind of light output and beam angle can I expect?

The pair produces a strong blue accent under the hull with a combined output designed to fill the water around the transom. The 180° wide beam disperses light broadly for attractive underwater wash rather than a narrow spotlight. This makes them ideal for ambient night-time illumination, attracting attention, or enhancing visibility near docks and swim platforms.

• 84 LEDs per light for dense, even illumination
• 180° wide-angle beam for broad water coverage
• Blue color for aesthetic accent and increased nighttime visibility

What materials and warranty support are included?

The BS4 prioritizes marine-grade components like 316 stainless steel and high-temp resistant sealants to extend lifespan in harsh conditions. The manufacturer states an IP68 rating after an April 2023 update and backs the product with a three-year warranty. A complete package includes two lights, screws, stickers, and an instruction sheet for quick setup.

• 316 stainless steel body and cool plasma polish finish
• IP68 triple-seal waterproofing with fully filled marine glue
• Three-year warranty and included mounting hardware

Who is this for: The BASIKER BS4 Marine LED Underwater Boat Lights suit boat owners who want a robust, high-output blue accent lighting solution that’s built specifically for saltwater use. They are a good fit for recreational boaters, anglers, yacht owners, and marina operators seeking durable underwater illumination with simple installation and reliable waterproofing.
