When single row bars don't deliver enough light for your needs, Black Oak LED's double row light bars provide the maximum illumination possible. By stacking two rows of top-bin OSRAM LEDs, our Pro Series 3.0 double row bars deliver 50,000+ lumens of professional-grade output. These aren't supplemental lights; they're primary lighting systems designed for serious applications across land and water.
Built with military-grade construction and backed by our lifetime warranty, Pro Series 3.0 double row bars combine raw power with proven reliability. Whether you're mounting on truck bumpers, boat T-tops, or equipment roof racks, these bars deliver the concentrated brightness needed for high-speed trail runs, offshore night navigation, emergency response, or commercial operations where visibility determines safety and productivity.
Perfect for Ford F-150, Toyota Tacoma, Jeep Wrangler owners, as well as center console boats, bay boats, and offshore vessels where maximum visibility isn't optional, it's required.
Double Row vs. Single Row: Which Do You Need?
The choice between single and double row comes down to mounting space and light output requirements. Our single row LED light bars measure just 1.8 inches tall, making them ideal for tight grille installations, behind-the-bumper mounting, or low-profile boat applications where stealth appearance matters. They deliver excellent visibility while maintaining a compact footprint.
Double row bars measure 3 inches tall and pack twice the LED count of comparable single row models. This translates to twice the lumen output from the same length light bar. The extra height accommodates the second row of OSRAM LEDs plus enhanced heat sink capacity, allowing sustained high-output operation without thermal dimming.
Choose single row when space constraints limit mounting options or when supplemental lighting serves your needs. Choose double row when your truck bumper, boat hardtop, or equipment mounting location provides adequate clearance and you need maximum forward illumination. Most serious off-road trucks, emergency vehicles, offshore boats, and commercial applications default to double row for the significant output advantage.
For truck owners with larger mounting locations (particularly bull bars, roof baskets, and overhead mounts) and boat owners with T-tops or hardtops, double row bars represent the professional standard. The 3-inch height fits standard mounting brackets and provides room for the oversized heat sinks that enable sustained high-power operation during extended use.
Sizing Guide: Finding the Perfect Fit for Your Application
20-Inch: The Versatile Standard
The 20-inch double row light bar fits almost every truck bull bar, tubular bumper, and aftermarket bumper configuration. This size delivers 27,500 lumens while maintaining manageable power draw, perfect for F-150, Tacoma, Ram 1500, and Silverado bumper mounts. The 20-inch length provides excellent width coverage for highway driving and trail visibility without overwhelming smaller trucks.
For marine applications, 20-inch bars excel as bow lights on bay boats and flats boats, providing excellent forward visibility for nighttime navigation without overwhelming smaller vessels. The compact length suits boats where space on the bow rail or T-top is limited but serious illumination is still required.
Most aftermarket bumpers include pre-drilled mounting locations spaced for 20-inch bars, making installation straightforward. The width-to-power ratio makes 20-inch the most popular double row size for general truck and small boat applications.
30-Inch: The Professional Choice
Hidden grille mounts and hood hinge installations favor 30-inch double row bars. The extended length provides better horizontal light spread for wide trail conditions while still fitting most vehicle widths. Producing 37,500 lumens, 30-inch bars excel at medium-range flood coverage combined with long-distance spot throw.
Center console boats and offshore boats running 24-30 feet benefit significantly from 30-inch bars mounted on T-tops or hardtops. This size delivers balanced coverage for navigation, fish-spotting, and docking approaches without creating excessive glare on the water surface. The length suits single-engine center consoles where a 50-inch bar would be overkill.
Hood hinge brackets position 30-inch bars at optimal height for forward visibility on trucks without blocking the hood. The length suits mid-size and full-size trucks where wider coverage improves ditch visibility and peripheral awareness during technical trail sections.
40-50 Inch: Maximum Coverage Applications
Roof-mounted truck applications and large boat hardtops demand maximum coverage, making 40-inch and 50-inch double row bars the standard choice. Our 50-inch Pro Series 3.0 delivers 55,000 lumens, enough light to spot obstacles or navigation hazards over 900 feet ahead. This makes them essential for high-speed desert running, offshore night running, or any situation requiring maximum forward visibility.
Large offshore boats (30+ feet), commercial fishing vessels, and twin-engine boats use 50-inch bars for maximum spread lights and long-range visibility during night running. The extended coverage proves valuable when navigating unfamiliar waters, running in heavy seas, or spotting floating debris at speed.
Large trucks, UTVs with roof racks, and commercial vehicles benefit from the extreme width coverage these bars provide. The extended length creates wall-to-wall illumination across wide trails, making them particularly valuable for racing applications and emergency response vehicles.

Beam Patterns: Why "Combo" is King
Double row bars carry enough LEDs to create the perfect combo beam pattern: spot optics in the center row delivering long-distance throw combined with flood optics in the outer sections providing wide peripheral coverage. This eliminates the need for separate spot and flood lights, simplifying your lighting setup while improving performance across multiple applications.
The center spot section projects a concentrated beam reaching 500+ yards ahead, allowing you to spot obstacles, wildlife, trail hazards, or navigation markers at distance. The flood sections on each end spread light horizontally, illuminating ditches, trail edges, boat sides, and approach visibility. This combination handles both high-speed straight runs and technical low-speed maneuvering without switching between different lights.
For marine applications, combo beams prove essential for safe night operation. The spot pattern illuminates channel markers, navigation buoys, and potential hazards at distance, while flood sections light the gunwales and sides for docking approaches, spotting floating debris, and maintaining awareness of your boat's width during tight marina navigation.
For off-road use, spot-only patterns work for open desert and highway driving but leave peripheral areas dark. Flood-only patterns provide excellent close-range coverage but lack the distance throw needed for higher speeds. Combo patterns deliver balanced illumination, which is why they dominate both truck and marine applications.
Our Pro Series 3.0 combo beams use precision optical reflectors to eliminate light scatter and focus every lumen where it's needed. The dual-row configuration allows us to fine-tune the spot-to-flood ratio, delivering optimal performance for forward visibility combined with edge awareness whether you're navigating trails or waterways.
Engineered for Abuse: IP69K & Thermal Management
Heat Control for Sustained Output
Double the LEDs means double the thermal load. Cheap double row bars dim after 10 minutes of operation because inadequate heat sinks can't handle sustained power. Pro Series 3.0 bars use oversized aluminum heat sinks with deep cooling fins that dissipate heat continuously, maintaining full brightness for hours of operation.
The die-cast aluminum housing integrates directly with the heat sink structure, creating maximum thermal transfer from the LED junction to the external cooling fins. This allows Pro Series 3.0 bars to run at rated output indefinitely without thermal protection dimming (critical for emergency response, extended offshore runs, commercial applications, and multi-hour off-road sessions).
For marine operators running long distances at night or commercial vessels operating extended shifts, this sustained output capability means consistent visibility throughout your entire run without performance degradation.
IP69K Waterproof Construction
Our IP69K waterproof rating exceeds the IP67/IP68 standards common in competing products. This highest-available international protection standard means Pro Series 3.0 bars withstand high-pressure washing, complete submersion, bow spray, and extreme weather exposure without moisture intrusion. The rating isn't just marketing; it's verified testing under the international IEC 60529 standard.
Sealed electrical connections use military-spec breathers that allow internal pressure equalization while blocking moisture entry. The polycarbonate lens is impact-resistant and UV-stabilized to prevent yellowing from constant sun exposure. These features make Pro Series 3.0 bars equally suitable for dusty desert environments, muddy trail conditions, or continuous saltwater marine applications.
For boat owners, the IP69K rating means these bars handle everything from dock washing to bow spray at 40+ knots without moisture intrusion or electrical corrosion.
Marine-Grade Construction
For saltwater boat owners and waterfront operations, our marine LED light bars include 360-degree ceramic coating that resists saltwater corrosion. The marine-spec housings use stainless steel hardware and enhanced sealing to handle continuous saltwater exposure, bow spray, and the harsh marine environment.
Whether mounting on fishing boats, offshore center consoles, work vessels, or waterfront equipment, marine-rated double row bars deliver the same high output with added protection against the accelerated corrosion that saltwater environments create. The ceramic coating prevents the white oxidation and electrical degradation common in standard aluminum housings exposed to salt.

Marine Installation Applications
Navigation & Offshore Running
Double row bars excel as primary navigation lights on offshore boats, providing the long-distance visibility needed for night running in open water. Mount 30-inch or 40-inch bars on hardtops or T-tops to illuminate channel markers, navigation buoys, and potential hazards at distances exceeding 500 yards. The combo beam pattern lights both the path ahead and the water on each side, helping you maintain situational awareness of your boat's position.
For center console boats running at night, hardtop-mounted double row bars replace multiple smaller spreader lights while providing superior forward illumination. This simplifies your electrical system and reduces the number of mounting points required.
Fishing & Working Lights
Commercial fishing vessels and serious sport fishing boats use double row bars as working lights during night operations. Mount 50-inch bars on commercial vessel cabins for maximum deck illumination during net operations, trap pulling, or processing catches. The high lumen output lights the entire working area without creating the harsh shadows that multiple smaller lights produce.
For sport fishing applications, T-top mounted bars provide spread lighting that illuminates the cockpit for bait rigging, line management, and landing fish without relying on dim cockpit courtesy lights.
Docking & Close-Quarter Operations
While primarily designed for forward illumination, double row bars with flood beam sections assist with docking approaches and marina navigation. The peripheral flood coverage lights dock pilings, neighboring boats, and tight approach angles. Combine with underwater LED lights for complete visibility around your vessel during nighttime docking.
Bay boat and flats boat owners benefit from bow-mounted 20-inch bars that provide excellent visibility for poling shallow water at night or navigating narrow channels where traditional navigation lights prove insufficient.
Why Choose Black Oak LED Double Row Light Bars
Pro Series 3.0 Performance Advantages
Our Pro Series 3.0 double row bars deliver advantages that separate them from competing products claiming similar specifications. Top-bin OSRAM and CREE LEDs mean we use only the highest-efficiency grade components from these manufacturers, not the cheaper mid-bin or low-bin alternatives that reduce both output and lifespan. This selection process costs more but delivers measurably better performance whether you're lighting trails or waterways.
The lifetime limited warranty backs every Pro Series 3.0 bar compared to the typical 1-2 year coverage from competing brands. This isn't marketing language; it's confidence in American engineering and veteran-operated quality standards that prioritize reliability over maximum profit margins. For marine operators, this warranty provides peace of mind that saltwater exposure won't void coverage.
Oversized heat sink construction maintains full brightness during sustained operation. Many competing double row bars experience thermal dimming after 10-15 minutes of continuous use, reducing output by 20-30% as internal temperatures rise. Pro Series 3.0 bars run at rated output indefinitely because the thermal management system handles the heat load from dual LED rows during extended offshore runs or all-night trail sessions.
Military-Grade Construction Standards
Every Pro Series 3.0 bar exceeds MIL-STD-810 environmental testing requirements for shock, vibration, and temperature extremes. This military specification ensures lights survive rough trail conditions, high-speed desert running, pounding seas, and the constant vibration of commercial vehicle or boat operation. The die-cast aluminum housing resists impact damage while providing structural rigidity that prevents lens separation common in cheaper plastic housings.
IP69K waterproof protection represents the highest international standard, verified through independent testing that includes high-pressure water jets and complete submersion. The sealed electrical connections use military-specification breathers that allow internal pressure changes without moisture intrusion. This construction handles everything from pressure washing to river crossings to bow spray at speed without compromising internal components.
UV-stabilized polycarbonate lenses resist yellowing and maintain optical clarity through years of sun exposure (critical for boats with no covered storage). The shatterproof lens construction survives rock impacts on trails and flying debris at sea that would crack cheaper alternatives. These durability features make Pro Series 3.0 bars equally suitable for harsh desert environments, muddy trail conditions, or continuous saltwater marine applications.

The combination of veteran-operated standards, American quality oversight, and lifetime warranty coverage delivers confidence that your lighting investment performs reliably for decades rather than failing after a few seasons of use.
Technical Specifications & Features
Advanced LED Technology
Top-bin OSRAM LEDs deliver industry-leading efficiency, converting maximum electrical power into usable light output. The binning process selects only the highest-performing LEDs from each production run (the same quality grade used in premium automotive and aviation applications). This selection costs significantly more than accepting lower-grade components but ensures maximum brightness and extended lifespan whether operating in desert heat or marine humidity.
Each LED operates within precise thermal and electrical specifications that maintain consistent output through the 50,000+ hour rated lifespan. At typical usage patterns (2-3 hours per day), this represents over 25 years of reliable operation. The 5000K color temperature produces crisp white light that reduces eye strain during extended driving or boat operation and accurately renders natural colors for improved obstacle identification both on trails and on water.
Power Efficiency & Compatibility
Double row bars deliver maximum output while maintaining reasonable power consumption. The precision LED driver circuitry regulates voltage and current to each LED string, protecting against voltage spikes and ensuring consistent brightness across the entire bar. This efficient power management prevents the overheating and premature failure common in cheaper alternatives.
10-30V DC operation works with both 12V and 24V electrical systems, making Pro Series 3.0 bars suitable for commercial trucks, heavy equipment, and large boats with 24V systems. The wide voltage range also accommodates voltage fluctuations during engine starting or alternator charging without affecting light output. Most recreational boats operate 12V systems and easily support double row bar power requirements.

Frequently Asked Questions
How many amps does a 50-inch double row bar draw?
Our 50-inch Pro Series 3.0 bar draws approximately 30 amps at full output due to efficient LED driver circuitry that maximizes light output per watt consumed. The included wiring harness handles this load with proper gauge wire and relay protection. Most truck and boat electrical systems easily support this draw, but for multiple high-output lights, consider auxiliary battery or upgraded alternator capacity. Marine operators should verify their charging system capacity before installing multiple high-output bars.
Will a double row bar fit my grille, bumper, or boat?
Double row bars measure 3 inches tall, requiring adequate vertical clearance for installation. Check your truck grille opening or bumper mounting location has sufficient height. Most modern truck grilles and bull bars accommodate 3-inch mounting. For boat T-tops or hardtops, measure available space on mounting rails or overhead structures. The 3-inch height fits most marine mounting locations designed for spreader lights. For tight spaces under 2.5 inches, our single row bars at 1.8 inches tall provide the alternative.
What warranty covers Pro Series 3.0 bars?
Every Pro Series 3.0 double row bar includes our lifetime limited warranty covering LED failure, housing damage from normal use, and electrical component defects. This warranty reflects confidence in military-grade construction and top-bin component selection. Warranty service includes technical support at 1-800-348-1287 and straightforward replacement processing for any covered failures. Marine applications are fully covered; saltwater exposure does not void warranty coverage on marine-rated models.
Can I use double row bars for saltwater boating?
Absolutely. The IP69K waterproof rating exceeds requirements for marine environments including continuous saltwater exposure. For saltwater applications, we strongly recommend our marine-specific models with 360-degree ceramic coating that provides enhanced corrosion resistance. These marine-rated versions use stainless steel hardware and additional sealing specifically engineered for boats, docks, and waterfront equipment where saltwater accelerates corrosion.
What's the difference between standard and marine-rated double row bars?
Standard Pro Series 3.0 bars use IP69K waterproofing suitable for freshwater boats and occasional saltwater exposure. Marine-rated models add 360-degree ceramic coating over the aluminum housing to prevent saltwater corrosion, stainless steel mounting hardware that won't rust, and enhanced sealing at all connection points. For boats kept in saltwater or regularly exposed to salt spray, marine-rated models provide significantly longer service life by preventing the white oxidation and electrical degradation that saltwater causes in standard aluminum housings.
