GreenBrite® is about Green Laser Levels.
The beam of a green laser level is 400% brighter and has more versatility, power, and intensity than a traditional red beam laser level. When you’re working indoors, finding a green laser is easier on your eyes and you can get the job done quicker.
The color green is closer to the center of the visible light spectrum (as shown below), so it’s easier for our eyes to perceive the color at night.
Different colors of light, and laser beams, are determined by the size of those tiny waves, called the wavelength. A normal red laser has a wavelength of 650 nanometers versus a green laser that has even more energy in a wavelength of 532 nanometers. The smaller wavelength gives humans the ability, when indoors, to see the green light better and more accurately than a red light.
Plain and simple, green is better because it is an easier color for the eye to see than oranges, purples and blues.
Look at the chart below again. The darker green color of the GreenBrite® laser level, at around 532 nm works best for a laser.
A lighter green color, however, is optimal for a spirit level (or bubble level) vial. In fact, green vials are the easiest to see, that’s why all professional levels have green vials!
Besides the science, we only have to look around to know that Green is the most palatable color to the human eye. Green is everywhere in nature. Green is on all informational signs on interstates and highways around the world. Green tells you to “go” at a traffic light.
The color of most laser levels is red. The color of the laser level is determined by the diode. Red diodes are much simpler to manufacture and are less expensive. But don’t confuse the cost of the diode with the quality of the laser level. Although our opening price point rotary laser level and one of our high-end rotary laser levels each are red, the quality is built into the product’s design, whereas the opening price laser is manual leveling while the high quality laser level is automatic leveling.
Green laser levels have been around for years, but only on laser levels that are very expensive ($3,000 and above). In 2005, Johnson Level was the first company to develop a green laser level with the same high quality, but at an affordable price. That’s Johnson and that is GreenBrite®.
