I ended up with the Bright Eyes light. I like it. It's definitely bright! I love the mounting style - nice and stable/sturdy, even with crazy pothole season right now.

Some things I think aren't great:
- strobe is actually crazystrobegahhh. I can't imagine it's energy-saving, because it's such a frequent strobe. But, it's definitely an attention-getter!
- There is so much cable. It's not very streamlined on my bike with all of that cable.
- The battery holder is annoying. It's two velcro straps that you have to unstring from the plastic loop thingies in order to take off your bike. You have to take it off your bike to charge it. So that's annoying.

But, so far so good! It didn't die during a 35 degree sleet/rain/hailfest commute home the other night, so I can attest to some waterproof qualities.
