The 4D-Optic Series is an off-road LED light bar built around OSRAM 5W chips and a reflector-and-lens optic that projects a long, focused beam. It comes in seven lengths from 10 to 55 inches, in straight or curved housings, with spot, flood or combo patterns, so it scales from a bumper bar on a daily driver to a roof bar on a chase truck. Output climbs with size, up to 55,000 lumens on the 55-inch bar, and the die-cast aluminum housing is rated IP68 with a lifetime warranty covering LEDs, defects and moisture. Against cheaper bars it stands out on output per inch and the moisture warranty; the trade-offs are a 6000K cool white beam and no wiring harness in the box.

Rated 4.9 out of 5 from 12 ratings, buyers are enthusiastic about the brightness and build. The main complaint is that the wiring harness has to be bought separately.
The 4D-Optic Series is an LED light bar that uses OSRAM 5W LED chips. Each chip's light passes through a 4D reflector and lens system. The projector-style lens focuses the output instead of letting it scatter, so more light reaches down range.
The housing is black die-cast aluminum with a PMMA polycarbonate lens. It is rated IP68 for waterproofing and runs on 10–30V DC. Output depends on bar size, from 6,600 to 55,000 lumens.
It comes with mounting brackets and hardware. A wiring harness is not included.
