What is Laser Level?
A laser level is just as important as all your other power tools. Laser levels produce a red or green light beam onto a flat surface to measure how level it is. Small traditional laser levels can be used for home DIY projects, while bigger, more industrial types are better suited for outdoor and construction job sites. Projects such as hanging picture frames or laying down carpets benefit tremendously from incorporating a laser level.
A good quality laser level cuts down on the amount of measuring you’d normally have to do. It takes the guesswork out of knowing whether a surface is a level or not. The most important thing to remember is that these lasers should never be directed at another person’s eyes. Look at the laser class to determine how safe the laser is. A laser class of 2 or 3R is relatively safe for eye exposure.
Most modern laser levels are manufactured with a low-intensity diode and are battery-operated, allowing you freedom of movement without tripping over long extension cords. The laser level you need will depend on the size of the project on hand and whether you’re working indoors or outdoors. A green laser level is much better for using outdoors, whereas a red laser is better for when you’re inside.
If you’re looking for cheap laser levels, you’re better off investing in a red one. If you only need to hang a few picture frames, then it wouldn’t make sense to buy an expensive professional laser level. In the same way, a large bulky laser level might cause more problems than good when used for small DIY jobs around the home. Most models can be self-leveling, which means that they can detect the level area with the help of internal self-leveling sensors.
A self-leveling laser level is more time effective and accurate than its manually set counterparts. You can divide most lasers into three categories; plumb, line level, and rotary lasers. Plumb lasers have a dot sight or reference point, unlike line lasers which project a visual line or two cross lines.
Dot lasers are commonly used for plumbing. Line lasers often have vertical and horizontal line capabilities. Lastly, rotary lasers project a level line around the entire room and are usually bulkier in appearance.
How Do Laser Levels Work?
Laser levels use a laser beam to pinpoint the origin of levelness on a flat surface. The beam of light projected from a laser level is emitted through a device called a diode. The word “laser” is actually an acronym for Light Amplification by the Stimulated Emission of Radiation. It’s quite a mouthful – but simply put, it’s when stimulated electrons give off a beam of light which is then collected by mirrors or prisms and pointed in a certain direction. The result is a laser beam.
Level lasers are used to project a line onto a surface. The thickness of the line will depend on the size of the diode. A thinner projection beam is more accurate than a thicker beam. Most models can be used indoors and outdoors. There was a time when they were limited to indoor use because the laser beam was too weak to be seen outdoors.
Nowadays, we have more powerful lasers with the added benefit of audible level detectors. These handy devices give off a beeping sound once the level has been reached. Most laser levels come with some kind of swivel attachment bracket or tripod to keep the laser level steady. A few have self-leveling capabilities, while others operate manually.
Self-leveling lasers can detect the level by using electronic sensors while manual levels make use of the traditional bubble vial. Self-leveling lasers might be more accurate in some ways, but their electronic extras will drain your battery power much faster than a manual laser level with a bubble vial.
How to Use a Laser Level to Hang Pictures
Hanging pictures or frames is probably the most common use for a small home DIY level laser. Sure, you can hang a picture frame or a piece of art without using a laser level, but why take the chances of having a skew end result? A laser level will help you hang straight and centered picture frames with no hassle at all.
Follow these easy guidelines, and you’ll find hanging pictures and wall art a breeze.
Step 1: To begin, measure the width of the wall you’ll be using and the width of the picture frame you’ll be hanging.
Step 2: Make a small pencil mark within the measured height.
Step 3: Use your tool to project a line horizontally across the pencil mark.
Step 4: Carefully adjust the laser until the bubble in the vial is centered. It should rest between the black lines. The beam should project onto or through the pencil mark.
Step 5: Once you’re satisfied that the laser beam passes correctly through the pencil mark, you can fasten or mount the laser level device.
Step 6: Next, you should measure the distance from the top part of the frame to its hanging point. This is usually the small hook or string on the back of picture frames.
Step 7: Using that measurement, measure down from where the pencil mark and laser beam meet and make yet another pencil mark at this point. This mark is where your picture frame will hang from.
Step 8: Carefully hammer a nail into this pencil mark. Alternatively, you can use a nail gun – read the full guide here. Next, place your picture frame onto the hook and align it with the laser beam before securing it in place.
In just a few minutes, you could have a perfectly straight wall decoration. So why would you even try to hang wall art without a laser level?
How to Check Laser Level for Accuracy
When taking on any sized project, it’s always better to measure twice and cut once. Although a laser level is your best and most accurate option for measuring levelness, it won’t hurt to do a double-check. The best way to do this is to check the accuracy of your laser level before you begin your project.
Even the best laser levels may become less calibrated over time and need to be checked regularly. Take a few minutes to follow these few steps, and you’ll save yourself the embarrassment of an unlevel project.
Step 1: Place your laser level on a tripod in the center of a large room. The exact position of the tripod is not important, but it should be at least 20 ft from the walls of the room.
Step 2: Turn your laser on and project a vertical line against the wall—mark off the point where the laser hits the wall with a pencil.
Step 3: Rotate the tool by 180 degrees and mark that point with a pencil. Compare the two marks and see if the difference is within the general range or not.
Step 4: Rotate the level by 90 degrees and mark off the point against the wall. Repeat the process for 180 degrees, then check the difference again. If the vertical beam is not within reach or the axis fails to show the proper results, your laser level may need to be calibrated.
What is the Best Laser Level on the Market?
According to reviews, the DEWALT DW089K Self-leveling 3-Beam Line Laser takes the prize as the best laser on the market. This model features three beams to aid in 90-degree layouts, as well as a 165 ft, range with full-time pulse mode. It’s accurate within 1/8 of an inch which is pretty damn close to being spot on. This model is ideal for installing cabinets and drop ceilings or windows and doors.
Reviews showed that this line laser level could take a beating without breaking down. Not only is the DEWALT DW089K sturdy and reliable, but it’s also steady and bright when placed on a tripod. Unlike other line lasers on the market, the DEWALT DW089K features a second plumb line which forms a 90-degree intersecting line on the floor and ceiling.
You can use this third line for layout applications without needing a second-line laser device. A micro-adjust knob allows the level to line up accurately. The whole unit is powered by simple AAA batteries. The device has a long-lasting 30-hour extended battery life even with its extra features.
The DEWALT DW089K is one of the best laser levels on the market. It’s a solid investment for any avid DIY warrior or construction job site. Take a look at the other reviews on our homepage.
What’s the Best Rotary Laser Level on the Market?
The Johnson-Level-Tool-99-006K-Self-Leveling Rotary System knocks all other rotary laser kits out of the park when it comes to features. With automatic horizontal leveling and a 90-degree manual leveling vertical plane, it’s sure to make any construction job easier. The automatic locking system protects the pendulum from any hard knocks or bumps when not in use.
Choose between 200, 400, or 600 RPM, depending on the size of the project at hand. It comes standard with a tripod stand, a laser detector, and tinted laser enhancement glasses for eye protection and better visibility while in use.
Positive reviews from customers state that the laser is accurate from a long-range as far as 70 ft. It’s perfect for figuring out where to professionally saw into the wood, or exactly where to use a telescopic ladder.
Reviewers also stated that setup is moderately easy thanks to the clear instruction manual. Additionally, top reviews stated that the laser was still highly visible and accurate even in bright sunlit conditions.
Moderately priced, this rotary laser level is the obvious choice for anyone looking for an affordable professional construction tool.
What is the Difference Between Red and Green Laser Beams?
The green or red light beam is not just there for color. The color of the beam can tell you quite a bit about the laser level in question. Green laser beams are up to four times brighter than standard red laser beams, thus making them more visible to the user. As a result, green laser beams are best for very bright conditions, such as sunny days or when you’re working under bright lights.
Both red and green laser beams will stand up to any challenge. However, there are some instances where green laser levels can perform better. Green laser levels have a much higher visibility rate, making them best for long-distance measuring.
Unfortunately, green laser levels and their diodes are more difficult to manufacture than standard red laser beams. This causes a fluctuation in the cost of green laser level tools, making them more expensive than red ones.
A complete assessment of the nature of the project will help you decide whether a red or green laser level is the best option. If you need a brighter laser for the outdoors, go green.
Laser levels are handy little devices that are just as important as power tools. And just like power tools, no two laser levels are the same. Not all laser levels come with the same features. You can get dot lasers, vertical and horizontal line lasers, dual beam lasers, cross line lasers, and more. Keep in mind that cheaper models probably won’t be a good idea for large construction projects but will fit the bill for smaller work around the house.
Whether you’re looking for a cross-line laser level, a green laser, a self-leveling laser level, or something else entirely, we hope our laser level reviews have helped you find the best laser level for you.
