Grote 64J31 - 30" Trilliant LED Off-Road Light Bar, 16,200 Raw Lumens – Combination Flood/Spot Beam
The Ultimate Night-Crushing Power for Field and Trail
The Grote 64J31 is the largest and most powerful entry in Grote’s off-road lineup, engineered to deliver maximum visibility for extreme environments. Spanning 30 inches, this dual-row LED light bar produces a massive 16,200 raw lumens (8,124 effective), providing the high-intensity output required for agricultural work, heavy-duty mining, and high-speed off-road adventures. By utilizing advanced LED technology, the 64J31 runs cooler and draws significantly less power than legacy HID or halogen lamps, protecting your vehicle's electrical system while outperforming the competition.
Hybrid Optics: The Best of Both Worlds
Featuring a newly reengineered Combination Beam pattern, the 64J31 eliminates the need for multiple light sources. The precision-focused spot optics project a powerful beam deep into the distance, while the wide-angle flood optics illuminate the immediate periphery. This "Far Flood" characteristic produces light that mimics natural sunlight (5700K), providing superior contrast and reduced eye fatigue so you can navigate hazards with total confidence.
Built for Hardcore Industrial Durability
Designed to survive where others fail, the 64J31 is housed in a robust anodized extruded aluminum housing and sealed with a hard-coated, UV-resistant polycarbonate lens. It carries a dual IP67/IP69K rating, ensuring it is completely dust-tight and capable of withstanding high-pressure steam cleaning. Whether facing sub-zero temperatures or intense desert heat, the internal thermal management and overvoltage protection ensure a maintenance-free service life in any climate.
