In the craft sector, cross-line lasers have now become indispensable. However, it is important to distinguish between the different lasers, as the green laser in particular has some striking advantages over the conventional red laser.
Particularly in special lighting conditions, the green laser is much more visible, which can be a great advantage when measuring.
However, as with any product, you have to accept some disadvantages that you should be aware of before buying. What exactly these are, whether a purchase is worthwhile and what you should absolutely pay attention to, we will clarify in the following text.
Top 10 Best Green Laser Levels
Why a green laser level has advantages in sunlight
Probably one of the most important aspects when choosing a laser is its visibility. Especially in sunny places, the sun’s rays are sometimes so intense that red lasers literally disappear.
You should pay particular attention during dawn and dusk. When the sun is very low, complications can arise.
While green lasers are usually still easy to recognise in such situations, red lasers have much greater problems.
This is due to the light spectrum of the sun, which is very similar to that of red laser light.
As a result, the red beam is superimposed by the sunlight and can thus become completely invisible to us humans. Only point lasers can still be seen on a wall (etc.) in such situations.
Better visibility through green lasers
But green lasers do not only have advantages in terms of visibility in special sunlight. In most everyday situations, the human eye can also perceive green laser beams much better.
The improved visibility can be up to a factor of 4. This means that measurements can be carried out much more accurately even in difficult light situations. But how can this phenomenon be explained?
It can be explained by the different wavelengths that produce the colours of the lasers.
The human eye reacts much more sensitively to green light, as this is in the wavelength range of approx. 530 nm. This spectrum is much easier for us humans to perceive than the 630 nm of red light.
For this simple physical reason, green cross-line lasers in particular have become very popular. The influence of the light is thus greatly reduced, which can lead to more accurate measurements when the sun is shining. Especially at larger distances of up to more than 40 m, the green laser can fully exploit its advantages.

The disadvantages of a green laser level
More sensitive to temperatures around +-10 degrees
Unpleasant for the eyes in the dark
Expensive price
However, in exchange for such advantages, one must also accept some disadvantages, as explained in more detail in the following section. For example, you have to reckon with higher power consumption for most cross-line lasers with green colour.
Although the difference in earlier technologies was somewhat greater, even most modern green lasers cannot rise to the same efficiency class of red light. Another negative aspect is the often limited temperature range in which green lasers can be used.
Although this has also improved noticeably in recent years, it can become quite problematic from temperatures of -10 °C or more than 40 – 45 °C. So anyone who uses a cross-line laser on a building site in winter or midsummer could reach their limits here.
Those who work at night or in dark rooms should also think twice before buying a green laser. These can be very uncomfortable on the eyes in such situations due to their enormous brightness.
Red light, on the other hand, remains neutral even in dark areas, which is why it is preferred for use in car tail lights or in astronomy – it is easy on the eyes even in the dark.
So while green lasers are more visible in sunny areas, they can be a disadvantage in dark rooms. Our eyes can get so strained, which hinders the measurements. The last aspect that should be mentioned is the usually more expensive price of a green laser. Since this is a much more complex technology, this is also reflected in the sales price.
All advantages and disadvantages at a glance
What to look for in the recipient
Especially if you can’t see the laser beam properly in unfavourable lighting conditions or in dusty environments, reading the laser meter becomes a real challenge.
A laser receiver can help by registering the focused laser beam, which enables accurate alignment during construction. However, the usability of receivers always depends on the laser itself.
For example, most laser receivers are only designed for red light, so they can usually only register this.
For this reason, there are relatively few receivers that can actually register green laser light, which makes it difficult for many people on the construction site to be able to use green lasers to their full extent.
This is also the reason why this can sometimes result in a significantly higher price. If you are looking at a favourable price, you will get away with a red laser and receiver much more cheaply than if you get these products based on green light.
