Lower wavelength in red makes it brighter comparitively. This have been gone over many times.

as far as i know, wavelengths in the 532nm are more brighter to the human eye than anything else, so if you think about it, wavelengths that are closer to 532nm are slightly brighter, like 445 is brighter than 405, and 638 is brighter than 650 etc.

Peak sensitive is at 555nm. 630nm is a little too orange for my liking though. >650nm is a good red imo...
