Default Current reccomendations?

Hey guys i wanted to thank the forum for all the help in getting me interested in this hobby! Ppplus i have one last question- for my 445nm, whats a good current to chose to drive it with that will keep the diode life long, but still have a bright beam for night viewing? Currently i have it set to ~1.25 amperes... Is that too much?
