The human eye is better able to recognize colors in the green spectrum, so a green laser is more visible under bright light conditions.
Green lasers have higher power requirements than red lasers. The initial light from the emitter on both is basically the same, but after the production of the light, everything changes. The light then as to be split into the wavelength of of either higher wavelength of red light or lower wavelength of green light. This takes different components for each. Red is simpler to produce and tune, and requires less power. Green requires additional and more expensive components, including diode, crystal, and other components to tune the frequency, wavelength and amplify power for the green light. This is more complex and tuning to green wavelength does use more power to maintain the perceived brightness. Your battery will not last quite as long with green.
In use, the advantage of green is really just in daylight. The human eye can perceive green better than red in bright conditions. in the dark, both green and red have about the same advantage. If you only plan to use the laser in the dark, and/or mostly care about lower cost, go red. If you want it for both day or night, and cost is less of a factor (both for the device and batteries), go green. The green, though, does legitimately cost more for both the device and battery replacements.
It costs more money to make a green laser, as opposed to a red laser.
Everyone wants green and those are more difficult to keep in stock. By elevating the price - it encourages price shoppers to settle for the red or take what little stock is available with green at the higher price. By having stock available in search engines it drives more clicks and potential customers - in turn price shoppers are less likely to go somewhere else for the same purchase so they settle here for the red. Hope that helps your online business understanding.
Then y not make all green wtf really . Every body wants more
its better ......better = more
Power requirements are higher for green, blue, IR, than red. Additionally, manufacturers still base production on historical sales, and buyers at vendors do as well. Because red is still the most common and there are customers set in their ways about red, until green has passed red in units moved per year, production and ordering on red will continue to be higher. It's easier or more beneficial to do a production run of say 90,000 units continuous, then it is to do 15,000. While green has certainly grown in the marketplace, it has not yet passed red in sales. Also, different colors have different uses, so no manufacturer is just going to replace red with green completely. Since 2020, COVID-19, global supply chain hasn't been what it was, but it is improving. Since less green units are produced than red, and there's so many vendors in the industry, supply is less than demand on the green, and as such, nothing dictates discounting green any further, as supply is minimal, many people are wanting green, those sell out first, and with the margin made on the green, vendors are able to further discount red, because they bought red in bulk, need to turn over inventory so they don't get stuck with the units. You don't want to have 2,500 of a version 1 in warehouse shelves, when version 2 is getting released, and the manufacturer is already taking orders for it.
