Rotating Laser Level

If you’re reading this article, you’re looking for the best rotating laser level, I’d suggest. Within the toll box full of laser tools, one of the most useful for most tradesmen and home renovators is the rotating laser level. This is a tool that you will wonder how you ever lived without once you start using it, you will never go back to the chalk line again.

So how does a rotating laser level work?

The actual rotating level unit sits on top of a tripod (this can be adjusted depending on the height you need, it simply screws on like you would screw on a photo camera onto a tripod, nice and easy. But the best thing is that most models will self adjust once you turn them on to make sure they are exactly level!

Once the unit have levelled, the laser (an acronym for Light Amplification by the Stimulated Emission of Radiation) beam will light up and a mirror will rotate above it at high speed. The mirror is adjusted at the factory (and enclosed inside the rotating unit so it can’t be tampered with) to shoot the laser horizontally and because of the mirror spinning at high speed, a laser line is made across the wall. So no more hassles with a chalk line, and no more pencil marks on the wall.

The very first rotating laser levels had only a dull laser beam and were generally limited to indoor use where there was not too much light, but improvements in the technology used (thanks to some of the bigger tool companies now producing them) has made them much brighter and usable outdoors as well as indoors.

Most rotating laser levels on the market today have a red laser light, but there is an increasing number being released with a green light, the reason being that the green light are apparently 400% brighter than the red. Although because green is a brighter light, more power is needed to run the unit and will drain your battery faster if not connected to a power source.


Many rotating levels now also come with a receiver (an attachment that can be clipped on to a dumpy stick) that can detect the laser light coming from the main unit so you can adjust an object up of down if you need the object level. This comes in VERY handy if you are doing form work for a concrete slab.

Both the main unit and the receiver are able to be run on batteries to make them entirely portable. Though it is highly recommended that you also keep the power charger handy, as you don’t want to be stuck on a building site with a rotating laser level that doesn’t work because the batteries have run out of charge.

When you buy a laser level, it will usually come in a pack that contains all you need to use it, plus a carry case to hold all off the accessories (i.e. the receiver and the power supply). Most cases will be very durable as the manufacturers understand that they will be used by tradesmen and most probably be thrown in the back of the car or van when not needed. It’s always a good idea to keep everything in the case to make sure you are never stuck without a part you really need.
