A laser level is an electronically powered device and they are able to project a beam of cultured light (generally red or green) along a vertical or linear axis. You can adjust the height at which these light beams are projected according to your requirements. There is however a range that a laser level can manage and this will differ according to different manufacturers and models.
You have to treat laser levels with care as they can be quite fragile. This will also ensure that the sensitivity of the device is maintained at a high level. There are some laser levels that come with a safety switch which can be useful in busy workplaces. Some also come with a tripod holder that will keep the laser level stable. A tile laser level will allow you to tile accurately along straight lines. This can otherwise be very difficult if you don’t have a guide and it will expedite the process as well. You can select a laser level that has an LED display that gives sufficient information about the levelling such as the angle that is projected and the height at which it is projected.
It is good to select a laser level that shows the remaining working time so you know when to charge it. There are many accessories that come with laser levels such as a holder for mounting, clips, clamps etc. Especially in construction, you need to choose a laser level that can be operated during daylight. There are devices that come with beam detectors and adjust the brightness so you will still be able to see it. Otherwise, the beam can be invisible in broad daylight halting your work.
There are many types of laser levels that you will come across. The basic spirit level will be able to accommodate beam angles of 180, 140 and 120 degrees. You can also find laser levels that come with extra vertical beams. These are called cross line laser levels. You have to read the manufacturer’s instructions to make sure that the laser levels are mounted correctly. There are also self-levelling devices that will make your job easier. These will be more expensive than devices that need to be levelled by the operator. A laser level uses a highly focused beam of light.
The thickness of this beam of light depends on light concentration levels of the specifications of the LED diode that emits it. For precision work, you will need to select laser levels that come with ultra-thin beams. The standard color of the beam is red and this will be visible indoors quite clearly. However, you may have some trouble locating this red beam when it is very bright or when used in outdoor applications. So you will need to opt for a laser level that provides a green beam that is much brighter than the red. However, you have to keep in mind that this consumes a lot more energy and cuts down your operation time.
