Our Extreme Series 5D LED Light Bars are one of our best-performing series of LED light bars. These curved light bars feature new 5D optics technology which couples an internal reflector to focus all light onto magnifying lenses which eliminate any internal loss of light and ensure all light is projected outward boosting its efficiency and output. The magnifying fish-eye lenses provide an extremely tight light pattern, reducing light loss due to refraction. With an IP68 rating, it operates up to 3 meters deep underwater continuously. Curved light bars are a popular choice for matching the curve of your windshield and wanting a wider beam pattern than a straight LED Light Bar.
