Aside from output, these profiles also offer different aesthetics. Straight LED light bars complement angular platforms with flat front ends, like a Jeep® Wrangler or Ford Bronco—alternatively, curved light bars best fit sweeping curves.

Flood: Projects a wide, diffused beam of light short distances. Flood beams are ideal for wide, up-close viewing, frequently employed as ditch lights to illuminate the sides of a trail.

The length of time that coherence is maintained is called the “coherence time”. The length that the signal could travel in a vacuum during that time is called the coherence length.

Double-row LED light bars offer potent performance and a slightly taller profile than their single-row counterparts. They feature double-stacked LED chips for double the output. Where space permits, double-row LED light bars are a significant upgrade over most single-row options.

Combo: Balances spot and floor patterns, projecting moderately far and wide. While combo beams cover more surface area, they offer less width than flood and less distance than spot beams.

A particular laser line is emitted at a very specific wavelength corresponding to one mode (light path) in the laser's cavity.

LED chips offer some of the most efficient light output on the market, producing loads of light while drawing minimal power from your vehicle’s electrical system. LED light bars capitalize on this technology, stringing multiple LED chips in a single, compact housing. The resulting light bar significantly outperforms halogens and other incandescent bulbs—all while using approximately 80 percent less energy.

Modular: Offering exceptional output and unforgettable styling, modular LED bars chain together several smaller independent lights, allowing you to customize dimensions, output, and more.

Spot: Projects a precise, focused beam of light long distances. Spot beams are ideal for long-distance viewing, though they offer little illumination of the immediate surroundings.

Modular light bars string several smaller LED pods into a single light source. With robust brackets and linked harnesses, modular bars operate as a single light while allowing far more customization than other light bar styles.

Straight LED light bars almost exclusively project light forward, featuring a flat lens and straight housing. Alternatively, curved LED light bars often feature a wider beam due to their convex, curved housing and lens.

So, what about beam patterns? LED light bars come in several, which directly impact light output. The most common beam patterns include:

Fog: Similar to flood beams, though positioned lower and angled toward the road. Fog beams help cut through fog, rain, and other inclement weather.
