50 Inch Marine Series Curved Double Row LED Light Bar – Pro Series 3.0 Unmatched Power. Proven Performance.

When you’re running after dark, only purpose-built marine lighting delivers the confidence and visibility you need. The 50-inch Marine Series Curved Double Row LED Light Bar – Pro Series 3.0 is engineered for serious marine applications, providing maximum forward and peripheral coverage while standing up to salt spray, humidity, vibration, and frequent washdowns.

For peak performance, our most popular configuration pairs the 5-watt high-output option with a Combo beam pattern, delivering powerful long-range illumination through the center spot optic while wide flood optics on the ends illuminate docks, channels, and surrounding water. The result is broad, balanced visibility ideal for offshore runs, night navigation, docking, and fishing—without sacrificing durability or reliability.

Premium Lexan Lens + IP69K Sealed Housing

Each light is built with an optical-grade Lexan lens—twice as strong as glass and engineered to resist fading or yellowing—paired with an IP69K-rated housing that blocks out salt, spray, sun, and high-pressure water. The result is a crystal-clear, fully sealed system designed to perform for years in the harshest marine or off-road environments.

Premium OSRAM® LEDs

High-efficiency OSRAM LEDs deliver exceptional brightness, clarity, and long-term reliability—engineered for demanding marine use and sustained high-output performance.

Complete Wiring Harness Included

Every light bar comes ready to install with a pre-terminated 12-gauge wiring harness, inline fuse, relay, and switch — plus heavy-duty stainless mounting brackets for a secure, professional-grade setup right out of the box.

Ceramic-Coated, Hydrex-Sealed Construction

Finished with a corrosion-resistant ceramic coating and sealed with our Hydrex gasket system for true IP69K performance. 316 stainless bolt-in mounts provide unmatched strength and durability in saltwater or off-road environments.

Precision Beam Patterns

Choose from spot, flood, or combo configurations for the perfect lighting spread. Our advanced reflector design ensures maximum throw distance and balanced side illumination for total visibility in any situation. Pro Tip: Combo is usually the best choice — it gives you the best of both worlds, with the spot pattern in the center for distance and the flood pattern on the ends for wide coverage.

Frequently Asked Questions

Q: Should I choose the 3-watt or 5-watt version?

A: The 5-watt version is our most popular option, delivering significantly more brightness and reach for night navigation and offshore use. The 3-watt version is ideal for lower-power setups or close-range applications.

Q: What makes the Marine Series light bar different from standard off-road light bars?

A: The Marine Series is specifically engineered for harsh marine environments. It features corrosion-resistant hardware, a fully sealed housing, and a marine-rated waterproof design to withstand saltwater spray, humidity, vibration, and long-term exposure on the water.

Q: What beam patterns are available, and how do I choose the right one?

A: This light bar is available in Spot, Flood, and Combo beam patterns. Spot beams project light farther downrange for navigation and high-speed visibility, Flood beams provide wide coverage for close-range illumination, and Combo beams offer a balanced mix of both for all-around marine use.

Q: Is this light bar suitable for T-tops, hardtops, or overhead mounting?

A: Yes. The 50-inch Marine Series light bar is commonly mounted on T-tops, hardtops, radar arches, and other overhead structures. Its mounting system allows for precise adjustment to minimize glare and optimize beam direction.

Q: How waterproof is the Marine Series light bar?

A: The Marine Series carries an IP69K waterproof rating, meaning it’s fully sealed against dust and can withstand high-pressure water spray. It’s built to perform reliably in heavy rain, rough seas, washdowns, and wet marine conditions.

Q: Will this light bar cause glare on my bow or deck?

A: Proper mounting and aiming are key. We recommend temporarily powering the light during installation to fine-tune the angle and reduce or eliminate bow glare. Slide the light bar back enough on the hardtop to eliminate all bow glare. When aimed correctly, the light provides excellent visibility without unwanted reflection.

Q: What voltage systems is this light bar compatible with?

A: The Marine Series light bar is compatible with 10-30V DC systems, making it suitable for a wide range of boats and marine electrical setups.

Q: Does the light bar come with a wiring harness?

A: Yes. The Marine Series light bar includes a complete wiring harness with fuse, relay, and switch, allowing for straightforward installation right out of the box.

Q: Is this light bar energy efficient?

A: Absolutely. The Marine Series uses high-efficiency LEDs to deliver powerful output while keeping amp draw low — helping protect your battery system during extended use.

Q: Can this light bar be used for night fishing or docking?

A: Yes. The wide, consistent light output makes it ideal for night fishing, docking, loading gear, and general deck illumination, improving safety and visibility after dark.

Q: What warranty does this light bar include?

A: All of the products in our Pro Series 3.0 line is backed by Black Oak LED’s limited lifetime warranty, giving you long-term confidence in performance and durability.
