If you're talking yellow to green, when I still had my yellow before I broke it attempting to mount the module into a keychain host, it did 8-10mw very consistantly for like three months after I pot modded it. At that power level, it was VERY much brighter than my 5mw Lyra. 594 is close enough [to 532] on the visibility arc that mw for mw, there is not much of a difference.
