Ok, it's dark and I went outside to do some measuring and this is what I came up with for the NiteHawk Emitter light.

Center of beem is 5.5 yrds in front of the bike. The spot is an oval shaped that is 1 yd wide by 3.25 yds long with an outer ring that's about 1 yd thick.

Hope this helps. Remember that I ride home with primarly street lights with some dark corners. With this light I can see the road and people can see me as well. It lights up the path well and I'm taking it easy on the way back.

Hope this answers some questions.
