Got these 5 mode lights for $53. Considering I don't ride that much at night it's good enough for when I need it. I keep it mounted but unplugged so the little green light doesn't drain the battery. Took it out during Irene, where she took out power in the neighborhood for 3 days. I'm not sure if it's truly 1,200 lumens, but I could go 20mph down the street without worrying, since it was so bright.
