C4-Series LED Light Bar – Race-Rated IP69 (10"–50")
The Brightest Bar We Make — Guaranteed
The C4-Series combines the strongest LED on the market — 7W chips at 105 lumens per watt — with our proven 4D projector optics for an output-per-watt figure nothing else in the lineup touches: up to 70,560 lumens on the 50-inch bar. The projection is engineered for extreme high-speed race vehicles running 140+ mph, where seeing far ahead isn't optional.
Rated for Race Abuse
This is our first bar rated IP69 — a step beyond IP68 — with upgraded weatherproofing, shock resistance, and impact protection for the toughest conditions on and off the road. All C4-Series bars are built on a straight housing.

C4-Series FAQ
What does IP69 mean over IP68?
IP69 adds protection against high-pressure, high-temperature washdowns — the rating you want when the bar takes direct pressure-washer hits and race-speed debris.
C4 vs. 4D-Optic — which flagship?
The 4D-Optic Series offers curved housings and a 55" option; the C4 runs stronger 7W LEDs for maximum raw output. If brightest wins, it's the C4.
Single row version?
Yes — the C4-SR Series is the same platform in a single row.
