I would buy the light again

I use this light on my early morning, pre-sunrise rides. I ride along a busy road first, that has no street lights - just the headlights of the cars & a little ambient light of some of the businesses that are open. I use the bright setting or the strobe so that cars are aware of me. I also use it on a rural road w/ absolutely no street lights, and very few homes; so no light, except moonlight on some mornings. I use the low setting on the rural roads, and can see perfectly. This is a great light - much more than I intended to spend, but the sales rep was a good salesperson! And I'm going to eventually buy another one - for my husband.

Bright & Powerful

i commute to work everyday -- early morning when its dark & back at night in the darkness -- this light takes care of lighting up the road in front of me.. battery seems to last a while --- i have never let it go all the way down to nothing... this light replaced a smaller nite rider light that came with a bulky battery pack... a good buy at a reasonable price !!

Great product

I have used incandescent lights for years, I finally did some research and went with the LED because of the weight and battery life. I can say I am very pleased and since most of our riding is technical. The lumen output along with the color rendering is perfect for night time single track!

superior customer service & great lights

This light has worked great for me but what really shined was their customer service response when I accidentally damaged the rubber switch cover on my light. When we called and explained the problem, they sent a replacement cover immediately at no charge.

Fantastic Light

Using it in winter/icy conditions, both on trails and in town. Really happy with the beam dispersal and ease of use/ charging.
