FCK Lightbars 4D-Optic Series LED Light Bar – Dual Row OSRAM (10"–55")

The FCK Lightbars 4D-Optic Series LED Light Bar – Dual Row OSRAM (10"–55") is a genuine FCK Lightbars product (LED Light Bars).

Key Features

• The 4D-Optic Series is the latest in LED technology and the brightest light bar in its class. OSRAM 5W LED chips fire through our 4D optic reflector-and-lens system for remarkable lumen output and projection that turns night into day — up to 55,000 lumens on the 55-inch bar.
• Sized And Shaped To Your Build: Seven lengths from 10 to 55 inches, in straight or curved housings, with spot, flood, or combo beam patterns — choose all three at checkout. Whether it's a bumper bar on a daily or a roof bar on a chase truck, there's a 4D-Optic that fits.
• Output By Size: 10" — 60W / 6,600 lumens
• Output By Size: 15" — 120W / 13,200 lumens
• Output By Size: 20" — 200W / 22,000 lumens
• Output By Size: 30" — 300W / 33,000 lumens
• Output By Size: 40" — 400W / 44,000 lumens
• Output By Size: 50" — 480W / 54,800 lumens
• Output By Size: 55" — 500W / 55,000 lumens
• What Does The 4D Optic Actually Do?: It focuses each LED's output through a projector-style lens instead of letting it scatter, so more of the light lands down range. Same watts, visibly more distance.
• Straight Or Curved?: Curved bars follow the lines of a roof mount and spread the beam slightly wider at the edges; straight bars are the classic pick for bumpers and grilles.
• Want This Platform With Color?: The RGB V-2 Series is built on the same 4D-Optic platform with a full multi-color halo added — zero performance loss.
