Laser levels are now a mainstream tool for professionals in the construction industry. A laser level uses a green or red beam projector to take measurements. Some of them come equipped with a holder, a rangefinder, and an LED display. Others are handheld devices for ease of use. Professional laser-level models come with various accessories, including clamps, holders, clips, receivers, and beam detectors.
How Laser Levels Work
Laser levels operate by projecting a highly focused beam. Red beams are standard and ideal for indoor work because they are not as visible. Green beams are up to five times brighter, making them versatile. They also consume more energy, which means they will only operate for a short time at a red beam laser level.

Ultimately, whatever the colour, the task they perform is the same. They self-level and provide accurate data. Newer models are fitted with electronic compensators to send accurate information.
The Benefits of Laser Levels
Laser levels serve many purposes, including making life simple regarding precise measurements, renovation, and assembly, whether laying a piping system or tackling a construction project. Laser levels are also useful for standard tasks, such as shelf fitting or wall tiling. They are also used to install doors, windows, HVAC, ceiling joists, and even sprinkler installation.
Many laser levels are equipped for solo use for tasks requiring two people.
What To Consider When Buying
If you are in the market for a laser level, you need to understand the capabilities of what each model can do. The most important parameters include measuring range, beam angle, battery life, and measuring accuracy. You can also consider accessories and levelling range. You will want your laser level’s capabilities to align with your job’s requirements.
If you frequently work in the renovation, you will want to consider how watertight and dustproof the tool is. Will it stand up in high humidity, is it designed for use outdoors or indoors? You want a tool that will operate in unheated rooms as reliably as in the heat. The standard operating temperature for typical models is -10 to +45 C°. However, you can find models that operate between -20 to +50C°.
There is a range of options for different types of laser levels. Horizontal beams are the most common type, but there are cross-lines and vertical beams. A 360° laser level can project at any angle. Each has its advantages, but the right laser level depends on the type of work you do and the projects you tackle.
Price is the final factor to consider. If you want a laser level that operates at 360° then you will have to pay considerably more than you will for a two-beam rangefinder. However, two (or even three) beams are generally more than sufficient for typical renovation projects. So, set your budget based on the level of quality you are looking for and the type of work you plan to do regularly.
