A very impressive little light. The lowest setting is equivalent to the single “on” setting of my original Tikka. The beam pattern is a good spot, and on high throws out far enough for night route finding and slow to mid speed riding. It’ll get outrun pretty easily on singletrack, but provides fine power for it’s size and weight.

The best thing about this light is that you can get it with a bike and helmet mounts. Nice and light and fairly bright.

Love the EOS! I had the original model, and it finally failed after years of daily riding. Upgraded to the new model (in the bike version) and WOW it’s bright but seemingly still decent battery life. Beam is a little narrow for general camp use, and both too bright and too narrow for reading, but great on the bike with excellent throw for such a small light. It’s always on my helmet, and even on the sunniest day it’s with me as a backup light.

I’ve kept one on my bike as a back-up in case my primary helmet-mounted light failed or ran out of juice. I never paid much attention to its battery life, but it had a decent beam for “being seen” as opposed to “seeing.” The mount, though, has finally failed. The plastic attachment on the back of the light snapped off. I suspect that the cold was largely to blame–I had been storing the bike outside in sub-zero temperatures. But I’m still a bit disappointed in the strength of the plastic. It sustained only a slight knock against the wall and snapped right off. I’ll rig something together with JB Weld and spare plastic parts, but it won’t be easy to move it around the way it was designed to do. All in all, still a good purchase.
