How To Choose 20 Inch Light Bars?

Having a light bar on your vehicle or with you during an off-road journey or hiking comes in handy. The light bar can give you better visibility, whether it is a dark area or precipitating. There have also been cases where people use them for signaling others.

But for these scenarios, a 20” light bar is convenient because of its slim, tinier, and more portable body. But a 20” light bar must have what it takes to survive those aforementioned conditions. Unfortunately, many items on the market fail to provide durability, performance, and user-friendliness, even though they promise it.

List Of 20 Inch Led Light Bars

  • The customized chips from Nilight work wonder to keep a constant intense light beam.
  • Its heat sink with streamline design has wind resistance and processes a faster heat removal.
  • The light bar has a durable bottom-slip mounting design.


  • It needs a wiring harness separately.

Let’s start with an item that gained so much attention from light bar customers and reviewers. The 60005C-A Light Bar from the Nilight brand has an attractive display with 126W of raw wattage. You can mount it on trucks, pickups, cars, boats, etc., with a steady setup.

Nilight uses customized LED chips on their light bars that intensify the light output and keep the brightness constant throughout the operation. Because of the multi-directional reflector cups, the light also gets a spread light. Its light is denser while consuming lesser energy.

For higher longevity, the brand utilized aluminum alloy on the heat sinks. It has a streamline pattern that can tackle wind pressure. Meanwhile, the 9-pieces of fins can keep the heat flowing fast and efficiently. The light bar has a weatherproof level of IP67. There are EVA strips and rubber pads that prevent water from getting inside.

The light bar comes with a durable set of mounting hardware that allows a bottom-slip mounting design. It is steadier than the ones where the mounting brackets stay on the side. You can adjust it up to 45° in order to change the beam focus. Nilight chose military aluminum for a higher sturdiness.

Buying Guide

Finding a decent 20” light bar is easy, but the best one is not. Like most electronic products, you need to check some ratings and stats to certify their qualities. It is on top of the build-qualities and other factors.

Our buying guide below contains some such points that you need to consider to spot a perfect 20” light bar among many options.

Most of them apply to other sizes as well. Also, some depend on your liking. So, it is ideal to create a priority list to follow. Take your time in the research to avoid getting a low-grade item.

Performance of the 20” Light Bar

A 20” light bar must provide a solid-light output with a wide and bright view. There is a difference between the brightness rating that manufacturers mention on the product description from the actual brightness.

The brands simply calculate the wattage and lumens from all the LED beads. It is the raw lumens. Meanwhile, the effective lumen and wattage are the stats you actually get from the housing. Manufacturers seldom mention them as they are almost always lower than the theoretical output.


Decide on an option between the straight and curved light bars. The latter is better in providing a broader light. The rear of the light bar can have round, square, angular, etc., shapes that may affect the mounting process.

We suggest triple or quad row bars if you want more brightness and wattage output. Note that they consume more energy and are costlier. If a slim design and budget option are what you are going for, a single or dual-row light bar may meet your need. But, they are usually less bright.

Beam Pattern

A light bar can have a wide or far beam pattern, depending on being a floodlight or spotlight. The former provides spread illumination, while the latter sends the beam far in the distance. Go for the light bars with combo beams. It allows you to get both simultaneously.


The durability of the light bar depends on having an aluminum housing for higher heat survivability, a PC/PMMA lens for endurance, and stainless steel mounting brackets for stability.

If you want to use it outdoor, look for at least an IP67 weatherproof level. Meanwhile, its heat dissipation system should have enough fin-spacing and technologies to let more heat flow outside.


Light bars have two mounting methods. Some have mounting brackets that mount on the sides, while others have a bottom-slip design. The former allows a 360° beam focus adjustment, while the latter provides higher steadiness. Aside from the brackets, you need other hardware and a wiring harness to install the light.

Concluding Message

Since light bars are so handy on dark terrain, their usage rises as time passes. Manufacturers are also upgrading the technologies. However, like many other products, planned obsolescence hinders it from its potential.

By pairing that up with false or tricky advertisements (like the factor about raw lumens we mentioned on the buying guide), it has gotten hard to find a 20” light bar that actually holds all the best qualities you want.

Hence, try to go through honest reviews and ratings from customers or YouTube to ensure the credibility of a 20” light bar. You don’t want to buy so many of them to try and find the best one. Leave that job to us.
