Flood, Spot or Combo – Which LED Light Bar Do I Need?

When yo are choosing a light bar for your truck ,offroad ,do you know what’s the beam pattern you need?

Unlike standard screw-in home bulbs, which throw light out in all directions, LED light bars concentrate their light in one direction.

The way the light beam is formed depends on each LED’s reflector and the shape of the lens. Modern light bars use computer-aided designs to achieve specific lighting patterns.

The lighting pattern trade-off for light bars is between distance and beam width. For the same luminosity, more distance requires less beam width and vice versa. When a design favors a wider beam width, you have a flood light. More distance is achieved by narrowing the light beam into a spot pattern.

A flood LED light bar typically has between 40 and 120 degrees of beam width.Spots are around 10 to 30 degrees. Keep in mind that flood and spot degrees vary between different models of led light bars.

So which one is best? It depends on the application. Both are useful and a common choice is to buy one of each or purchase a combo bar that has spot and flood functions combined.

A combo works by assigning the jobs of the spot and the flood light to different sections of the light bar. It can do this by dividing flood and spot reflectors along the bar’s length or by splitting the functions between rows. The best LED light bar of one manufacturer allows you to custom design your flood to spot ratio with swappable reflectors.

Spot beam pattern with long length ,Flood beam with wide width. Combo is the combination of spot and flood ,will be good for choice of your led light bar.
