Ok, I've got two solid weeks in with this thing. Its been dark, cold and rainy. I thought it was lasting about 4 hours. The little panel over there on the right says run time 3 hours so that's accurate. It takes 2-3 hours to charge. Its bright but I didn't realize just how bright it is until I was under a bridge this morning and noticed the beam lighting things up on a far wall of the bridge as the road turned. I'm not sure what the four modes are unless off is a mode. Mine has high, low and blink. and off.

I've been riding with this light a few weeks now and am very impressed. Very bright and does a great job of illuminating New Orleans pot holes (who are we kidding, caverns) and holds a good charge. Would definitely recommend. Cheers.

I ordered this light for my son’s new State bicycle. It’s really bright, and I know he will be seen while riding. Thanks for creating a safe product.

Great light, long lasting easy to charge

Though I haven't had a chance to try it out the replacement headlight you sent me it charged up in about 4 hours and promises to be just what I need for my twilight commute to work. Thanks for the fast service in correcting the problem.

Great product! Just as bright and Greta to use!!
