Ø80 mm Stainless LED Underwater Light 5W – White or Blue

The Ø80 mm 5W LED underwater light is engineered for situations where compact size and efficiency are paramount. At its core is a single high-power LED consuming just 5 watts, yet capable of delivering an impressive amount of light for its size. Thanks to a modern LED chip and lens, this model achieves a bright, focused beam comparable to a traditional 40–50W bulb, but with vastly lower energy use and a far longer service life (over 30,000 hours expected).

The lamp’s housing is made of marine-grade AISI 316 stainless steel, polished to a mirror finish, which not only gives it an elegant appearance but also provides robust protection for the LED and internal driver. The face diameter is 80 mm and the profile thickness is 25 mm, allowing it to sit almost flush on the transom or hull surface. Installation requires drilling a small hole for the power lead and fastening the fixture with three screws (stainless steel screws are included). A rubber O-ring seal on the back ensures no water can seep behind the unit once properly installed.

Electrical Characteristics: The light can operate on both 12V and 24V systems, thanks to an integrated driver that accommodates a wide input range. This means you can use it on almost any vessel – from small fishing boats with a 12V battery up to larger yachts with 24V banks. Drawing only 5W, it is extremely energy-efficient, allowing you to run it at anchor for extended periods without worrying about draining your battery.

Color Options: The product comes in two LED color variants – cool white for those who need the brightest, most visible underwater illumination (for example, to light up a swim area or enhance overall visibility around the stern), and blue for owners who want to create a luxurious, lounge-like effect after dark. The blue option is highly prized for decorative purposes – it accentuates the clarity of the water and sets a relaxing mood, especially when entertaining on board. Some boaters even choose blue for its gentler impact on night vision and its attractiveness to certain marine life, adding a bit of fun for night fishing or viewing sea creatures.

Applications: This model is well-suited for mounting on the transom of speedboats, sailboats, RIBs, and even jet skis where space might be limited but stylish illumination is desired. The 80 mm footprint allows it to fit on relatively small transom surfaces. Thanks to its low profile, the lamp can also be installed on the sides of the hull (near the waterline) to create interesting light accents while underway. IP68 ingress protection ensures it can operate submerged indefinitely – the unit is completely sealed against water and will perform reliably even when left underwater for long durations.

For maximum effect, you could install twin units – one on the port and one on the starboard side of the transom – using white LEDs for strong illumination and/or blue LEDs for atmosphere. Maintenance is virtually nil: the stainless steel face resists marine growth and wipes clean easily, and the LED light source never needs bulb replacements like traditional lamps. With this compact underwater light, your vessel will be more visible and attractive at night, enhancing both safety and enjoyment on the water.
