532nm vs 520nm

[Pman]

I haven't tested myself but I would guess that I might also not be able to tell a 532 and 520nm apart without seeing the side be side for the same reasons you post 10fenny. I was also disappointed when I first got a 520nm until I compared. Nice that 532nm over spec modules are so cheap (buy from Fasttech) though as my favorite color is green.
