So as my name suggests, I am looking for the most powerful (brightest) laser I can get my hands on. I already have a 1.3W 520nm on its way so now I am looking into the blues. I have been searching the forums and YouTube for a little while trying to compare the 7W 445nm to the 4W 470nm, but I am having a hard time finding a consistent comparison between them. Some comparisons make the 445nm look pretty purplish and the 470nm a solid blue color while others comparisons make the 445nm look like a bright blue while the 470nm looks right smack in the middle between green and blue. I know neither of these comparisons are very accurate so does anyone who has both of these wavelengths know of an accurate picture/video showing their true colors? How does the divergence on the NUBM07 compare to the divergence on the NUBM44-V2? I would be using the G8 lens with a SanWu 3X BE on both. Thanks!
