I'm going to make a new laser and trying to decide on what diode to use. I want to use either a "3W 9mm 445nm" or one of the new "2W m462" Would the m462 appear as bright as the 3W 445nm because of its higher wavelength? Is the color of 462nm noticeably different than a 445nm diode? I already have a 2W m140 diode and don't know if the 462nm would be that different.
