Green vs Red Laser Level: What’s the Difference?

green-vs-red-laser-level

green-vs-red-laser-levelLaser levels come with either green or red beams for increased visibility. These beams help you get the most accurate results in a way that is easy, efficient, and convenient. But what color beam should you get? Many people assume that color options don’t offer much difference in performance, but this is far from true.

To find out exactly how green laser levels and red laser levels differ, read on. This comparison article covers both beam colors extensively and provides you with advice on how to choose between the two. Let’s get to it.

Overview of Green Laser Levels

Although red laser levels are more popular than their green counterpart, green laser levels are easier to use, have an increased range, and are more powerful. This, in part, means that green laser levels include more details, are more expensive, and die quicker.

Visibility

When talking about either level’s visibility, you’re going to have to think back to your high school science class. The color green sits right in the middle of the spectrum of visible light. Even if you don’t remember what this means, that’s okay. You just need to know that this makes the color green the easiest to see to the human eye.

As a result, a green laser level is easier to see than the red, which falls to one end of the visible light spectrum instead of the middle. Since the color green is easier to see, it has clearer edges and further visibility. For example, the color green has a wavelength interval of 560 to 520 nm and a frequency interval of 540 to 580 THz.

If you are an average person, those numbers probably mean nothing to you. To put it simply: these levels mean that it provides four times as much light as a red level.

When working indoors, green laser levels will have a visibility range of 50 to 60 feet. Even more impressively, green laser levels can be used when working beyond 60 feet outdoors. All in all, green laser levels have superior visibility and viewing range.

Construction

Since green laser levels are so powerful, they have more parts than a red laser level. For example, green laser levels will have an 808 diode, a frequency doubling crystal, and more. As a result, green laser levels take more parts, time, and money to build than a red laser level.

Price

Due to the increased parts, green laser levels are more expensive than red ones. This is why most lasers have red lights, not green ones. They are more expensive to make and require more time, as well. In fact, green laser levels are between 20% and 25% more expensive than red ones. This makes them less economical than red laser levels.

Battery Life

Once again, the extreme power of a green laser level comes with another downfall. Their battery life span is much shorter than the red counterparts. Whenever the battery starts to die, the visibility of the laser will be affected as well.

Best For

Green laser levels are best for those who need maximum visibility. When working outdoors, for example, the green laser level is the clear winner. Select the green laser level if you need enhanced visibility and don’t care about battery life and price.

In contrast, you would want to avoid the green laser level if you are on a tight budget. Since they’re so much more expensive than a red laser level, those on a budget will probably not be able to afford a green laser level.

Pros

  • Increased/maximum visibility
Cons
  • More expensive
  • Shorter battery life

Overview of Red Laser Levels

If you have seen any laser type, including laser levels, you have most likely seen products with a red laser beam. These laser levels are the most popular by far due to their more economical price and extended battery life. Of course, they offer less visibility than the green option.

Visibility

As we mentioned before, the color red falls on one end of the visible light spectrum. This makes the color red much more difficult to see than the color green. It has a wavelength interval of 700 to 635 nm and a frequency interval of 430 to 480 THz. This means that the color red is four times less bright than the color green.

When working indoors, you will be able to see the color red between 20 to 30 feet. So, you don’t have to scroll back to the green laser section, this is about half of the range of green laser levels. If you are working in areas below 60 feet outdoors, then the red light laser can be suitable.

Overall, these facts mean that red laser levels offer less visibility than the green counterparts. When working nearby, this will not be as much of an issue. However, if you are working in larger areas, the red laser light will not provide enough visibility to help adequately.

Construction

Even though red laser levels offer lower visibility, one area that they beat out green laser levels is in construction. Red laser levels require fewer parts since they’re not as powerful. This makes them easier and more economical to build.

Price

Since construction is simpler and more affordable, the price of red laser levels is also more affordable. Those on a budget will especially lean toward the red laser level for their affordability. Purchasing a red laser level and a laser level detector, making it easier to see the red light, is often more affordable than purchasing a single green laser level.

Battery Life

The lower power of the red laser level means that it has longer battery life. This is great for those who don’t want to replace the battery frequently or who only intend to use the laser level sporadically and don’t want to have to think about the battery. It could also save you money since you will need to buy fewer batteries.

Best For

The red laser level is best for those who are on a budget and working in tight areas. Since it offers lower visibility, it is only suitable for short ranges, both indoor and outdoor. Despite this, it’s affordable price and extended battery life makes it an excellent option for many.

However, if you are working in more spacious areas, you should forgo the red laser level and select a green one instead. Its lower visibility means that it will be inherently useless if used for more extensive ranges.

Pros

  • More affordable
  • Longer battery life
Cons
  • Lower visibility

Which Laser Level is Best for You?

Situation Which Laser Level to Select
Indoor 20 to 30 ft range Red laser level
Indoor 30+ ft range Green laser level OR red laser level with a detector
Outdoor 1 to 60 ft range Red laser level
Outdoor 60+ ft range Green laser level
Budget pick Red laser level

Ultimately, deciding on the best laser level for you depends on your budget and working area. You should select a green laser level if you are working in longer ranges. The green laser level has enough visibility that you can use it for larger areas. In contrast, select a red laser level if you are working in short ranges. It’s lower visibility and more affordable price will make it worth it for this kind of work.

In terms of budget, the red laser level is also more ideal. Because of its lower visibility and simpler design, it is more affordable, making it the best option for those on a budget. If you aren’t as concerned about budget, then you might want to go ahead and select a green laser level since it is more powerful and offers you more features regardless of the range.

Factors to Consider When Buying a Laser Level

Knowing what factors to consider when selecting a laser level can help you purchase the best option for your needs. Below are the four most important factors to consider when buying a laser level. These factors will help you select which color beam you need, as well as what model to get.

Range

The first question you should ask yourself is, “What range will I be working at?” The range tells you what color beam you should get. You can opt for the red laser level when working in smaller ranges, but you should select a green laser level if working in more extensive ranges.

Related to the range is indoor versus outdoor use. Normally, indoor use is a shorter range. You can probably work with a red laser level if most of your work will be indoors. In contrast, you will probably need a green laser level if you’re working outside. Of course, you still may need a green laser level inside if the building is large and has a wider range.

Visibility

You also need to consider the visibility of the laser level you select. The beam’s color will affect the visibility. As you already know, green laser levels offer more visibility than red ones. The color beam is not the only factor that impacts visibility, though.

The reliability and manufacturing also affect the visibility. For example, higher-end laser levels are likely to have better visibility since they include better and more powerful parts. Battery life will also affect visibility. As the battery dies, the visibility decreases. Make sure your model has a good reputation and battery life for increased visibility.

Accuracy

Even if you select the most visible laser level, it means nothing if it is not accurate. Make sure the laser level you choose is accurate with exact measurements. If not, your project will be slightly off, even though you could see the beam clearly.

Manual vs Auto

When selecting a laser level, you will have two options: manual or auto. Auto lasers, or self-leveling lasers, give you a true level line on their own. This makes the levels more accurate. On the other hand, manual lasers will require you to set them up properly to get accurate results. If they are disturbed, they will keep on running even though they aren’t level anymore.

If you know how to set up a manual laser level, you will have no problem getting an accurate result. However, you might want to select an auto laser level if you’re unsure how to use a manual one independently.

    Conclusion

    Even though red laser levels are more popular, green laser levels have a place in construction, too. Green laser levels offer increased visibility, but they are more expensive and have shorter battery life. Red laser levels, in contrast, offer lower visibility but cost less and have longer battery life.

    With all this in mind, choose the laser level color beam based on your intended working range and budget. Larger ranges will require a green laser level, while smaller budgets will be most suited for red laser levels. It’s relatively simple.
