4D-Optic Series LED Light Bar – Dual Row OSRAM (10"–55")
The Flagship — OSRAM Power Behind 4D Projector Optics
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.

4D-Optic FAQ
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.
