shiningbeam has a relatively new rc-n3 up for sale http://www.shiningbeam.com/servlet/t...h-N3-II/Detail

for a dollar more than the Q5 you get a tad bit of a brighter light with a slight green tint.

though i wouldn't say it's a *better* bike light than the 2-mode Q5, since it does have a very white tint which i think would be more noticeable making the output difference between the lights negligible.
