The word “laser” is an acronym for Light Amplification by the Stimulated Emission of Radiation. While the science is a bit complicated, basically, that means that lasers emit radiation in the form of visible light. In the case of a laser level, that radiation light is emitted by an LED (light-emitting diode) semiconductor, and then tightly focused by use of an internal mirror or prism into an intense beam of light. To hang pictures with a laser level, first, determine where you want to hang your pictures and the desired layout. Next, use your laser level to cast a beam of light onto the wall where the pictures are to be hung. Finally, we evaluated the laser levels for overall ease of use, as well as value for the price. All test results and scores were then tabulated and the top products determined. Rotary Level Lasers are less common than line lasers but are equally as useful. They project the line in a rotary fashion and are usually on the bigger side. There are two different types: dual-slope and single-slope. If you are just hanging a single lightweight picture on the wall, you don’t really need a laser level. But if you are hanging several pictures in a row, are hanging a single heavy mirror or picture that requires multiple nails to secure it in place, or are hanging pictures along an incline, such as over a staircase, then you’ll find a laser level makes the job far easier than eyeballing it or relying on a measuring tape and pencil.

Huepar have made this simple but powerful green laser level that works well both indoors and outdoors. It is an extremely accurate laser level that is easily set up and can mount on most surfaces. The whole specificity of such laser levels lies in the special design of the prism receiving a beam of concentrated laser light. Most laser levels will display laser markings vertically and horizontally along a single wall, while others boast a 360-degree feature allowing you to take accurate readings around an entire room at once. Importantly, a laser level will provide a true reading regardless of any irregularities on the surface it’s placed on. As soon as self-levelling units are a few degrees from level, they’ll snap to the vertical or horizontal, eliminating margins of error. Key specs – Size: 86 x 70 x 110mm (LWH); Range: 25m; Accuracy: ±0.5mm/m; Self-levelling angle: ±4 degrees; Key features: Green laser beam, 360-degree function, zip-up caseWhile there are many more products on the market, the best 360-degree laser levels above are the ones we found reliable, accurate, durable, easy to use, offers a good warranty and promises to save time and improve the quality of your work. Probably the most common of the laser levels is a line laser. It will project a vertical or horizontal line onto any surface you are working on. You can have a 360 degree projection and a forward projection laser measure.

The tool passed a 1m (3ft) drop-test, which means it can withstand a rough construction environment. The unit is easy to mount on high ceiling grids due to its compact and lightweight nature. The tool comes with 4 "AA" alkaline batteries that offer 10 hours of continuous use. Its indoor working range is 200ft (60 meters), and it is expandable to 300ft (90 meters) for outdoor use when you use it with a laser detector.Thanks to this construction of the prism and the laser beam that passes through the top of the cone, a circular laser plane with a 360-degree sweep is formed. Advantages of the 360° laser level Self-levelling feature. The laser is automatically leveled and the laser will flash when out-of-level. For me, I cant really see the need to go 250 times further but if you expect to be doing a lot of outdoor work then going for a green laser beam will make sense and it would be the best laser level for you.

BM3 positioning device with a retractable foot, strong magnets, and a ceiling grid clamp to grip the laser and attach it to objects for exact positioning. You are going to read a lot of opinions on red laser and green beam laser. Technically speaking the green laser beams can provide a lot more power ( up to 250 times more ) so you will find that they tend to be used more for outdoor use. So you can deduce that the red beams are used more for indoor work. Your conditions, or where you are using it will dictate which colour is the best laser measure for you.If you are taking on a major DIY home remodeling project or need a laser level for professional use, then the CIGMAN 3x360° 3D Green Cross-Line Laser Level is worth the expense. This pro tool beams a green laser line that can be seen up to 100 feet as long as it's not being used in the brightest sunlight. Indoors, we had no problem in seeing the crisp, green lines across the length of the testing room. The tool has three lasers, which can be used individually or in various combinations: one 360-degree horizontal line and two 360-degree vertical lines. That lets you create grids for complicated installations of cabinets or other large items. Seven hours operating time with lithium battery, two hours operating time with aa batteries with all laser beams on

Ryobi also offers a Telescopic Pole for laser levels. The lightweight pole extends from 1,200mm to 3,200mm by twisting each of the three sections. On one end is a rubberised foot, on the other a spring loaded platform which tensions the pole between the floor and ceiling. Once in place, it provides a useful and very stable platform to mount the laser levels on, using its ¼-inch screw. Not cheap, but it’s an extremely useful accessory. We tested 25 laser levels in The Lab, evaluating them for accuracy, ease of use, durability, and overall value in a variety of scenarios that require precision, such as installing cabinets.Find out how our rotating laser levels are designed to be robust and easy to use for long-distance levelling, aligning, squaring and slope tasks
