It may just be my imagination, but if you unscrew the head on the Q3 a little bit it looks like it's tightens the center beam and add a little extra throw... try between a 1/2 to 1 whole turn...
hmmm, It appears to me as if the hotspot is SLIGHTLY tighter. not that much, but maybe someone can look farther into this. Who knows... /ubbthreads/images/graemlins/icon3.gif
i went outside to check the throw, i found that 3/4 turn worked the best for mine. it's just slightly brighter at the center. but i like it... /ubbthreads/images/graemlins/smile.gif
