Laser levels are used in a variety of construction and engineering applications, but they’re commonly used for concrete and asphalt work. Grading, landscaping, and surveying companies use laser levels for a variety of tasks. Framers also used them to check for the square alignment of openings (such as windows, doors, dormers, and skylights). A laser level uses an amplified and highly-focused beam of light that’s emitted from a solid-state device called a diode. Also called LED’s, these devices are found in many devices (such as digital clocks, remote controls, and televisions).
The beam can be used as a visual chalk line when a straight and level reference point is needed. The size of the beam will depend on the size of the diode. And in this particular application, smaller is better because it will be more precise. With a wider beam of light, the actual level point can be located anywhere inside the width of the beam. The first laser levels could only be used indoors, because the beam wasn’t bright enough to be seen if it was used outside. Now, more powerful laser levels can be used in outdoor environments as well. And many of them can be used with a detector that will “read” the beam.
Here are five of the best rotary laser levels that can be used for construction.

This rotary laser level kit is a comprehensive solution to a number of outdoor and indoor leveling applications. The manual dual-slope feature allows you to adjust the slope angle of the rotary laser level on both the X and Y axes. It also comes with a hard carrying case that can hold all the accessories included with this kit. The device has an accuracy of 1/16 of an inch for every 100 feet, which goes up to 2,000 feet if you use the included receiver.
This rotary laser level by Leica Geosystems is an expansion of the company’s broad portfolio of rotating lasers. It’s the best rotary laser level for getting a professional solution with a good price-to-quality ratio, because it will allow you to quickly level and align what you need to build on a construction project while eliminating costly errors.
This rotary laser level has a number of useful features, which can include but may not be limited to:

Frequently Asked Questions
How does a laser level work?
A laser level uses an amplified and highly focused beam of light that’s emitted from a solid-state device called a diode. These light-emitting diodes (called LED’s) can be found in a number of devices, and the same technology is used by laser levels to establish a visual “chalk line” you can use to get a straight and level reference point.
What is the self-leveling range of a laser level?
The self-leveling range of a laser level refers to the deviation value or difference from the level of the laser housing for the device’s internal leveling mechanism to work properly. It’s a feature that can spare you the extra time it takes to make tedious adjustments.
Can I use a laser level in sunlight?
There isn’t a single laser level that can be completely visible outdoors under direct sunlight for more than a few meters. That’s why most rotary laser levels have an electronic receiver, which can find the beam within certain distances. If you’re looking for the best rotary laser level for your specific needs, be sure to look at what we have at Engineer Supply.
Can a laser level hurt my eyes?
The most common vision-related problem with using any type of laser leveling device is flash blindness, which is caused by the eye being exposed to an extremely intense flash of light. This can last anywhere from a few seconds to a few minutes, but it can also be permanent.
How important is the accuracy of a laser level?
It depends on the job you need to perform. What really matters is whether the precision you need is met while you're using the rotary laser level. All of them have a rate tolerance that can be anywhere from 1mm to 20mm. An interior job within a short range can use any rating with the given band. But for long-range exterior work, a range of 1-4mm inside 20mm would be fine. In more specialized engineering applications, the tolerance of a laser level is more critical.
