What Are Laser Levels?
Laser levels are devices that project a beam across a surface, helping you to create a straight and accurate line for construction projects. Laser levels keep your measurements accurate. Guidelines exist for the use of a laser level. If you know how to operate your level, this will help you finish your projects. They can be found throughout the construction trade and in private homes. Does this Spark an idea?

Tripod-Mounted Laser Levels
-
The most accurate laser levels are lasers that mount onto tripods. The main purpose of the tripod laser level is to survey large areas, usually outdoors. The tripod will allow you to adjust the height of the laser level. This can help with a project like a drop ceiling. Tripod laser levels are also helpful with fencepost alignment and to check that your deck or porch is flush. Be careful to keep all items that may interfere with the beam of the laser away. Tripod laser levels are more expensive than the hand-held versions.
Hand-Held Laser Levels
-
Hand-held laser levels are more appropriate for smaller spaces. With the hand-held laser level, you place the laser across the surface you wish to project a level line onto and turn it on. Most will level themselves, which makes them easy to operate. This eliminates worries that you do not get a true straight line because the level is uneven. The hand-held laser level costs less than a tripod laser level. Some examples of projects for this style of laser include alignment of cabinets and shelves, leveling floors and ensuring your door frame is even.

Safety
-
You must always use caution when you work with a laser level. A laser concentrates light into a very fine point, which can damage the retina in your eye. It is possible to blind people if the laser strikes their eye. Never step into a beam, and be aware of your surroundings to avoid eye injuries.
Class II Laser
-
A laser level uses a Class II laser. This is a medium-power laser. Class I lasers present a very low risk to humans. Class III lasers represent a large risk and are found in areas such as medicine and electronics. Class II lasers do present some risk, if eye contact occurs. Beyond eye damage, no other risk is present from a Class II laser. The brightness of a Class II laser level is about the same range as the brightness of the sun.
Types of Lasers
-
Several basic styles of lasers exist. A rotary laser can project a beam 360 degrees around. The rotary laser is often used in large outdoor areas and works with a laser receiver, to help see the laser over large distances. The dot laser acts like a laser plumb bob. It can provide a level line in conjunction with a point on the wall or floor. The laser line level projects a straight line in one direction. The laser line level is usually used for smaller indoor projects.
