The Best Green Laser Level

Have you ever needed to level an outdoor patio in the sunlight and the light from a red laser was washed out by the sun? Green lasers typically have a higher power output and run at a different wavelength making them easier to see in sunlight.

Prices are coming down and there are more manufacturers on the market now. Let’s run through the options and see which one is the best!

How to Use a Laser Level

First, place the base on a flat surface, a tripod, or even a metallic surface like a metal stud. If you’re using a tripod outdoors, make sure the ground is steady and the tripod won’t move.

Turn on the level with the switch and you’ll see the laser emit lines on the surface ahead of you. Be careful not to look directly into the laser as it can damage your eyes. Allow the level a few seconds to self level and you’ll see the line come to rest.

The bottom of the Huepar has built in magnets to easily attach to metal surfaces. One tip is that if you already have a camera tripod, there’s a good chance you can use it as a mount if it’s the standard 1/4 inch tripod thread.

If you’re using a tripod, adjust it to the correct working height that will give you the line about where you need it.

What is a Self Leveling Laser?

If you’ve ever used a typical straight bubble level before, the concept of a self leveling laser is similar in that the tool uses gravity to measure weather a surface is perfectly horizontal or not.

Most self leveling lasers levels use gravity to align a pendulum straight down. After you place the level and the pendulum finishes swinging, it will be vertically aligned for the internal lasers to emit perfectly horizontal and vertical lines. Some self leveling lasers use magnets to hold and mirrors to split the light emitted from the laser.

What is the Difference Between Red and Green Laser Levels?

Outside of the color of the emitted light, the main differences are battery life, brightness, and price. A green laser level typically requires more energy to product the different wavelength. This will affect the amount of time you can use the laser and how bright it will be when the battery wears down. Red beam lasers can sometimes be harder to see outside in direct sunlight.

You’ll first notice the bright green color of the Huepar laser once you power it on using the included 4 AA batteries. It’s very easy to see both the horizontal and vertical lines indoors. Having both lines is a wonder for hanging picture frames on walls.

What does square, plumb, and level mean?

One object is square to another when both of their planes intersect to make a right angle.

An object is plumb when it’s in a line perpendicular to the horizon. You can also say it’s perfectly straight up and down.

An object is level when it’s in a line perfectly parallel to the horizon.

When Do you Need a Laser Level?

  • Leveling gravel for a road or path
  • Stone work for outdoor patios
  • Kitchen countertops and backsplashes
  • Mounting a TV to a wall
  • Drywall or sheetrock work
  • Ceiling work
