Upgrade your off-road lighting with the FCKLightBars 4D-Optic Series Dual Row LED Light Bar, engineered to deliver exceptional brightness, long-distance visibility, and rugged reliability for trucks, Jeeps, UTVs, SUVs, and overland builds. Featuring premium OSRAM 5W LED chips paired with advanced 4D projector optics, this flagship light bar produces up to 55,000 lumens of crisp 6000K daylight illumination, giving you the confidence to tackle trails, worksites, and highways long after the sun goes down.

Available in 10-inch, 15-inch, 20-inch, 30-inch, 40-inch, 50-inch, and 55-inch lengths, the 4D-Optic Series is offered in both straight and curved housings with your choice of Spot, Flood, or Combo beam patterns, making it easy to customize the perfect lighting setup for your vehicle.

Premium OSRAM LEDs with Advanced 4D Projector Optics

Unlike conventional reflector light bars, the 4D-Optic Series combines high-output OSRAM 5W LEDs with a precision-engineered 4D reflector and projector lens system. This advanced optical design captures and focuses more usable light downrange, creating greater distance, improved beam control, and wider coverage with less wasted light.

Whether you’re navigating technical trails, racing across open desert, or working after dark, the 4D-Optic Series delivers bright, focused illumination exactly where you need it.

Straight or Curved to Match Your Build

Choose the housing style that best fits your application:

• Straight Light Bars provide a clean, aggressive appearance and are ideal for bumpers, grille mounts, headache racks, and front-facing applications.
• Curved Light Bars contour naturally to roof racks and windshield mounts while providing slightly wider peripheral illumination.

Combined with multiple beam pattern options, the 4D-Optic Series offers a lighting solution for virtually any off-road vehicle.

Built for Harsh Off-Road Conditions

Constructed with a rugged black die-cast aluminum housing, durable PMMA polycarbonate lens, and sealed to an IP68 waterproof rating, the 4D-Optic Series is designed to withstand rain, mud, dust, vibration, and harsh off-road environments. Operating on 10–30V DC, these light bars are compatible with nearly any 12V or 24V vehicle.
