Most industries commonly use laser modules—particularly in construction, installations, and surveying. These modules project vertical, horizontal (and sometimes both) lines in green or red to deliver fast, accurate long-distance measurements.
But, what is the difference between the colours red and green? Is there any practical advantage to using one over the other? The fact is, there is absolutely no difference when it comes to accuracy. Both are (pun intended) laser-accurate. Ultimately, the key differentiators between the two are price, brightness, visibility, and battery life.
Red lasers:
Red lasers have always been popular, however, as green lasers have come into play and technology has moved along, you’ll find that red lasers are becoming less and less in demand. But, if red lasers are equally as accurate as green lasers then why are they falling to the wayside?
The reality is that red lasers do not produce quite as big a range as green lasers which means that they can be difficult to detect in certain conditions. However, you can use a ‘laser detector’ to help improve your visibility.
That said, if you were to view a red and green laser of equal power side by side, the green laser would appear to be far brighter and more visible than the red laser. – Red lasers typically have a longer battery life than green lasers – Red lasers are generally less expensive than green lasers – Red lasers are compatible with most receivers (as most traditional receivers can only detect red light).
Green lasers:
Green lasers are visible to the human eye in a much wider range of lighting than red lasers are. This means that you can work using a green laser with great accuracy and precision even in the worst conditions.
This makes the green laser superior to the red laser when working all year round, indoors and outdoors, come rain or shine. Green laser light is 10 to 50 x brighter than a red light laser. This means that even if you are working in direct sunlight, you will still be able to see a green laser quite clearly.
Additionally, a green laser can be visible over longer distances. – Green lasers are 10 to 50 x brighter than red lasers – Green lasers have a much farther distance than red lasers – Green laser tools typically have more components and better laser diodes which is why they tend to be more expensive.
