I don't shoot lumenoks anymore....they shot the same out to about 30 then start dropping a lot...I just had trouble with them cutting on with my arrows (Carbon Express Maxims)... I started shooting nockturnals this year and they shoot with my regular nock out to 40....maybe a nudge lower at 50 but i'm shakey at that distance so it's really hard to tell...if i remember correctly they weight 10 grams...so pretty close to regular nock..
