Black Oak LED 6 Inch M-Series Double Row Light Bar Review

Black Oak 6 Inch M-Series Marine Double Row Light Bar

Black Oak’s 6-inch, dual-row, marine grade LED light bar is the epitome of versatility. There are countless places where you can mount this light bar: be it the boat, RV or a remote cabin – it brings bright, clear light that wipes away even the deepest pitch-black darkness. On boats, it is the perfect size to fit beneath cabinets or seats, in the engine compartment or on the bow or stern for clear navigation over lakes, bays, rivers or estuaries. A pair mounted for partial rotation make superb nighttime fishing lights on smaller craft.

This compact 6-incher comes in three choices of beam pattern: spot, flood or a combo beam with center spot and side floods. The corrosion-proof mounting brackets allow vertical rotation, so you can aim it at exactly the optimum angle. With either 12 3W or 5W high-performance OSRAM LEDs, you can put out a total of 3,732 or 6,600 raw lumens of void-free illumination, respectively.

These light bars are built to the highest intrusion rating possible to withstand harsh environmental conditions including saltwater. The rugged aluminum housing, custom lens seal and 10 stainless steel lens fasteners add up to an industry-leading IP69K rating, which extends to the Deutsch waterproof wiring harness connectors. High quality LED driver circuitry is bolstered by a massive, heavily finned, integrated aluminum heat sink, which keeps the LEDs running at 95 percent efficiency while extending their life to their full lifespan of 50,000 hours.

The Black Oak 6-inch marine grade light bar measures just nine inches bracket to bracket and has a full height of 4.2 inches, so it is easy to fit in small places. They also take well to pole or tripod mounting, so you can take them ashore when you find that perfect landing.

Black Oak, dual-row marine light bars are hands down the highest quality lights in the industry with the best light-to-cost ratio. Their quality is backed by a cash-back guarantee and lifetime defect warranty.

What’s in the Box?

Every Black Oak M-Series LED light bar includes a complete mounting hardware and wiring harness kit, so you can complete installation with only a few common hand or power tools right out of the box.


Although this 6 inch light bar from Black Oak LED is specifically designed for marine use, its white color often complements land vehicles better than their black color version. On small craft, the size is perfect for mounting in almost any nook or cranny. Most buyers use them for navigation, deck or docking lights.

Several buyers who own sailboats have mounted a pair mid-ship on both the port and starboard sides to illuminate the mainsail when sailing at night or in twilight. Boat owners with onboard electrical systems appreciate not having to down-convert their 24V or 28V systems, since this light bar can run on an input voltage anywhere from nine to 30VDC comfortably. A few reviewers have placed one in the engine compartment, which fully illuminates the engine and peripheral components.

Whether navigating fresh or saltwater, boat owners need the highest reliability lights they can buy, and these Black Oak light bars meet that requirement handily. These get high marks from reviewers for their ability to brave salt spray, submersion, high humidity, wide temperature ranges and hard jostles. Their IP69K intrusion rating is the highest in the industry, which means they reject water, mist, fog, dust and even ice easily. Many buyers note the confidence these light bars impart, since having 12 LEDs per bar means they keep shining even in the unlikely event one or two happen to fail.


Black Oak LED’s M-Series 6-inch LED light bars will endure the harshest marine environments as well as or better than their much higher-priced competitors. Expect the highest performance in terms of illumination, reliability and durability from these products, plus the highest value in terms of pricing. No other LED light bar is made better, shines brighter or makes your lighting budget go further.
