It hard to beat this one. Except maybe with this one. Or this one. Word of caution, they don't put out 1200 lumens. They put out about 700 lumens but that's not too bad. The beam pattern on these tend to be fairly narrow compared to other LED bicycle lights. I personally like the very narrow beam but others don't. If the beam is too narrow, you can get diffusers that spread the beam out some.

I would also suggest getting at least 2...one for the bars and one for your head. Three is even better. At less than $20 a light, you can afford to get as many as you like.
