What Is Laser Level

Laser level is a mainstream tool typically used in the construction and surveying industry for levelling and aligning applications. They project a constant red or green line onto a surface on a horizontal or vertical plane and can be used for anything from hanging a picture to professional building work.

5 Reasons to Use a Laser Level
 

Accuracy
Laser levels provide up to three times more accuracy than traditional spirit levels. If you want your finished project to be visually perfect, it's important that you get things as straight and plumb as possible. That's where laser levels come in handy. The beam of light emitted by laser levels is incredibly accurate, helping you make sure that everything looks symmetrical and level, even if your walls are not perfectly flat or perpendicular.

 

Less time spent on site
When working on a project, time is of the essence. Every minute counts and all that. Laser levels eliminate guesswork and save you time, giving you more time to enjoy other facets of your life instead of hanging around construction sites waiting for someone else to tell you what's next.

 

Professional results
Laser levels can be useful in any situation where precise, accurate results are required. A laser level is ideal for all kinds of construction, interior design or home improvement projects. Unlike tape measures and spirit levels, laser levels are able to provide you with accurate measurements regardless of your angle relative to your starting point. This makes them much more versatile than their counterparts.

 

Improved communication on site
A laser level makes it easier for everyone on site — from your builder to your next-door neighbor — to communicate, making miscommunication less likely. Coordinating construction can be difficult, but with a laser level, you won't have to worry about what anyone else is doing. They'll know exactly where you want them to be, and how far they are from hitting that mark.

 

Less accidents on site
Construction is inherently dangerous. Everyone who works on building sites knows that safety comes first. A laser level allows you to see where your lines are, so you don't have to rely on others so much, which can save your job if other workers don't feel like getting their hands dirty that day. Inaccurate measurements cause injuries and cost companies money — and they also make your boss unhappy. Even minor mishaps, such as stubbed toes or accidentally hitting someone with a hammer or screwdriver, can delay construction and turn a quick project into a drawn-out ordeal.

How a Laser Level Works

 

Laser level projects a green or red beam. The laser is a highly focused and multi-amplified beam of light emitted by the LED diode. Its thickness (the smaller the better) depends on the parameters of the diode and the level of light concentration, ultra-thin beam enables maximum precision and minimises the potential error almost to zero, even over long distances of the order of 30-50 meters. The colour of the beam is also not without significance. The red, or standard, is optimal for indoor work, but may not be visible outdoors or in very bright rooms, so more and more models have a green beam that is four or even five times brighter than the red one. Of course, this does not come without a cost – the green beam consumes more energy and offers 1/2 or 2/3 less operating time than the red beam.


The heart of each laser level is the optoelectronic compensator, stabilized magnetically or pneumatically. Both types perform the same task: they self-level the device, moving within the limit of free movement specified by the manufacturer (usually +/- 3° to 5°). The point is to automatically align the laser beam with respect to the rotational axis for accurate horizontal and vertical alignment. This is only possible if the device is placed horizontally. If the allowable tilt margin is exceeded, many models will signal their inability to level by sound or light signals. When it comes to stabilizer types, it is necessary to explain their principle of operation. Namely, magnetic compensators (found much more often) have a kind of pendulum controlled by a system of magnets. In the case of a pneumatic stabiliser, the pendulum is positioned by a vibration damping system using air. The effectiveness of both is basically identical, except when a strong magnetic field acts on the magnetic compensator (nearby transformer or high voltage line). This can lead to system disruptions. More recently, some spirit levels have been fitted with so-called electronic compensators, which feature internal electronic level sensors sending information to a processor that controls the operation of the servo motor system. It is the most expensive, but at the same time the most accurate solution.

 

How to Use a Laser Level

Lasers are typically fast and easy to operate which means you can get to work straight away. Please note that there are a variety of types of lasers on the market, which may operate in slightly different ways. But for the most part, to operate your laser:

  • Attach the laser level to the tripod (if using). Most tripods have adjustable legs and a built-in levelling bubble. Use these to make sure your laser is level on the tripod and that it's not anywhere likely to be knocked over.
  • Turn the laser on and calibrate it by making sure that the bubble is aligned inside its vial (unless it is self levelling, it will do this for you - give it time to do so).
  • It will produce a level beam onto the surface you're working on.
  • Identify a point on the ground at your desired height and project the laser onto the surface you need to level. The beam can be a dot, a line, or a combination of dots and lines depending on the laser you're using
  • If you are using a laser detector, fix it to a levelling rod with a clamp. Slide it up and down the rod until it beeps. When you hear a beeping sound coming from the detector, it means that it has found the beam.
  • Fasten the detector in place and make the necessary measurements.

How to Keep a Laser Level in Accurate Working Condition
 

Laser levels are built to be as durable as possible, but they're still fragile devices that must be handled with care. When operating the laser level, treat it with the same care that you would a camera or smartphone. When you're done, follow these steps to safely store a laser level: 

1

Lock the pendulum. Many laser levels feature a pendulum lock, which serves two purposes. First, this disables the self-leveling function, which allows the laser level to be used at any angle that the tool is positioned in. Second, and most important for storage, the pendulum lock locks the internal components of the laser to help prevent shock as the tool is moved.

2

Remove the batteries. Batteries shouldn't be left in tools during long-term storage as they have a tendency to corrode. If your laser level features an internal rechargeable battery, pay close attention to the manufacturer's instructions for storage.

3

Wipe away dust and debris. Clean off the tool's outer shell before placing it in storage to prevent scratches and other damage. Most user manuals recommend using a soft, damp cloth to wipe off the laser level.

4

Dry off any moisture. After cleaning, thoroughly dry the laser level using a dry, soft cloth.

5

Place the tool in the provided case or a hard, protective toolbox. If the laser level comes with a case, always utilize it for storage. If no case was included, we recommend buying a protective toolbox to store the laser level in.

6

Place it in a moderate, dry area inside and out of direct sunlight. Store the laser level somewhere that doesn't see extreme hot or cold temperatures or high humidity. Keep it out of direct sunlight.

7

Once it comes time to use the laser level again, place new batteries or fully charge the internal rechargeable battery. Check the laser level's accuracy before use, following the manufacturer's instructions to do so.

Laser Level Safety

 

 

Even though the beam coming out of a laser level has only a small amount of power, it is concentrated enough to harm your eyes. Anyone using a laser level should follow the below precautions:
● Never stare into a laser beam.
● If you are wearing tinted lenses to increase the laser beam's intensity, remember tinted glasses do not offer protection to the eyes from direct exposure of the laser beam.
● Do not attempt to repair or dissemble the laser tool. If unqualified persons attempt to repair this tool, serious injury may result.
● Make sure to read the instruction manual and for your safety do not use your laser level until you are familiar with how it operates.
● Never point a laser where it can encounter any vehicle with a driver, people, or pets.
● Don't let children play with lasers.
● Purchase a laser level with the strength compatible with your intended usage.
● Always turn the laser level tool off when not in use or left unattended for a period of time.
● Remove batteries when storing the tool for an extended period of time (more than 3 months) to avoid damage to the tool should the batteries deteriorate.
● Use only original parts and accessories purchased from the manufacturer or an authorized dealer. The use of non-manufacturer parts and accessories will void the warranty.

Factors to Consider When Choosing the Right Laser Level

There are many different laser levels available for use and so there is a lot to consider when trying to choose the right laser level for you. What laser level is right for you? Here are some things to consider:
Accuracy: Laser levels are more accurate than other tools such as the spirit levels.
Manual vs auto: Auto lasers, also known as self leveling lasers, essentially does most of it for you. Once it starts up it will eventually give you a true level line. It will also stop if disturbed, meaning you won't get any inaccuracies. Manual lasers aren't less accurate than auto lasers if they are set up properly.
Green beam vs red beam: Green beam lasers are easier to see because they appear much brighter. They are only used for large scale, indoor projects where the line needs to be seen instead of using a laser level detector.
Indoor or outdoor usage: Are you using your level for indoor or outdoor projects? There are different types of laser levels that could be better suited for it's intended use.

What Are the Laser Level Types
 

Dot laser level
Dot laser levels, sometimes called spot lasers, cast two, three, or five lasers. This allows the user to create a point from floor to ceiling, a level point of reference, and a 90° reference point.
Cross-line laser level
Cross-line laser levels produce horizontal and vertical laser levels, either individually or simultaneously.

Rotary laser level
Rotary laser levels, also known as rotary lasers, use a beam of light that spins so quickly that it gives the illusion that it's one solid 360° plane. These planes can be horizontal or vertical.
Combination laser level
Combination lasers project both spots and lines independently or simultaneously.

3-plane laser level
3-plane laser levels use three beams, two vertical and one horizontal projection lines. The vertical lines cross, creating a 90° angle.

FAQ
 
 

Q: What is the main advantage of using a laser level?

A: The laser provides reliable level measurement and is unaffected by density changes, foam, gas concentration and pressure fluctuations. Also, lasers can work reliably even in the presence of agitators which is a key benefit for this application.

Q: Are laser levels worth it?

A: Laser levels are useful for any project that you'd use a standard level or a plumb line and more. These projects include hanging cabinets, mounting electrical receptacles, hanging pictures, hanging gallery walls, mounting curtain rods, hanging wallpaper, laying tile and many more.

Q: Why do I need a laser level?

A: A laser leveling device will emit a beam that will give you a straight-line reference along any surface (such as a wall or floor). And because most laser levels can be mounted to a tripod or wall, your hands will be free to hammer nails or line up whatever needs to be straight.

Q: Which is better red or green laser level?

A: Did you know that a green laser light is ten to 50 times brighter than a red light laser. Green lasers are much more efficient and visible in areas of broad daylight and direct sunlight. They are also able to travel longer distances, which is why they are so popular on construction sites.

Q: How far is a laser level accurate?

A: A quality laser level accuracy is plus or minus 1/16th of an inch (0.0625 inches) per 100 feet; 10 times greater than spirit level accuracy of over 1/2 of an inch (0.6 inches) per 100 feet.

Q: What would you use a laser level for?

A: Laser levels are typically used in applications where a straight and level reference point is needed over a larger surface. They are almost like a visual chalk line. Use them for fitting dado rails, hanging picture frames and all other professional levelling applications where your point transfer need to be exact.

Q: How does a laser level work?

A: Laser levels work by projecting a laser through a clear window from an internal pendulum-mounted laser. The pendulum allows the lasers to self-level with the help of magnets.

Q: What types of projects are laser levels good for?

A: Laser levels are useful for any project that you'd use a standard level or a plumb line and more. These projects include hanging cabinets, mounting electrical receptacles, hanging pictures, hanging gallery walls, mounting curtain rods, hanging wallpaper, laying tile and many more.

Q: How do you use a laser level to hang pictures?

A: To use a laser level to hang pictures, set up the laser to project a line across the wall, then adjust the line to fall where you wish to hang the picture. For single pictures, laser levels are helpful for adjusting the picture to hang level or lining the picture up with certain architectural features. For multiple pictures, laser levels are great for aligning frames, such as on a gallery wall.

Q: How do you use a laser level without a tripod?

A: Use a laser level without a tripod by simply placing it on a relatively level surface. If the surface is too far out of level, the laser level will let you know that it is unable to self-level by either flashing the beam or illuminating an indicator light. Most laser levels can self-level on surfaces within around four degrees of level.

Q: How to use a laser level?

A: Many laser levels are handheld, but some can also be mounted on a single point rod or other piece of equipment. Using a laser level requires only one person. Some models are self-leveling. For other models, the operator adjusts the legs of the laser level tripod until the leveling bubble is centered. Once turned on, the laser level will project a line onto the surface, which can be marked as needed.

Q: Can I use a laser level on the floor?

A: You can use a surface laser leveling device by setting it at the benchmark high spot that you want throughout the floor. A single laser line means you have a consistent elevation that's on your benchmark point. But if you see two lines, the floor is either lower or higher. From there, you'll need to rotate the device few degrees and mark spots that are low or high until you make a complete circle. This is where a rotary self-leveling laser comes in handy.

Q: How do I choose a laser level?

A: Not all laser levels are created equal, and there are many things you have to consider before you decide to buy one. Laser leveling devices can be a useful alignment tool if you find one that's suitable for the kinds of tasks that you'll be performing. Dot lasers are the most basic types of laser levels, and they're typically used for simple tasks that are occasionally performed around the house. A rotary self-leveling laser is made for more complex construction projects that need more precise measurements.

Q: Does a laser level level itself?

A: If your laser level doesn't have self-leveling functionality, you'll need to manually adjust the device using the bubble vial on the side of the level. A laser level with self-leveling functionality will adjust itself after you turn on the device, so make sure to give it a few minutes when you first turn it on.

Q: How do I know if my laser level is accurate?

A: Turn the laser exactly 180 degrees in the same place and wait for the laser to self-level and start spinning again. Following step 3, draw another mark on the wall and label 'point B'. If the difference between point A and point B is greater than 6mm you should send your laser in for a service and calibration.

Q: Why is my laser level laser not working?

A: It's well worth trying another set of new batteries and do not mix different types nor mix old batteries with new. Sometimes even new sealed batteries are faulty, so always try two sets. Bare in mind that new lasers with rechargeable batteries will not have been fully charged.

Q: What is good accuracy for a laser level?

A: A quality laser level accuracy is plus or minus 1/16th of an inch (0.0625 inches) per 100 feet; 10 times greater than spirit level accuracy of over 1/2 of an inch (0.6 inches) per 100 feet.

Q: What are three safety rules for using laser levels?

A: Do not look into a laser beam. Don't look down specular reflections (e.g.: from mirrors or other reflective surfaces). Don't stare at diffuse reflections. Don't look back along the optical path through an experiment with the laser energised.

Q: What can make a laser level inaccurate?

A: The reading will vary with beam position, in some cases as much as ±2%. Therefore to get the most accurate reading, always center the beam on the sensor. Some laser sensors have small apertures, in some cases as small as 5mm.

Q: Do laser levels lose accuracy?

A: Certainly a major drop or knock can cause problems, but also, excessive exposure to vibrations can also make a laser level go out of calibration. So what you want to do is regularly check your laser for calibration before any major job, but also on a regular basis.
