The Taz is my favorite battery light that you can buy right now. It's a tradeoff - it doesn't go as far down the road, but it's really good at having an wide, even beam pattern that isn't horrible for oncoming traffic (the neutral-white led is helps to).

Problem with most of the brand name lights nowadays is the crappy runtimes. 1.5 hours on high? I mean, they're not even trying. I'm thinking of buying 2 lights so I can run both on medium and get good lighting with respectable runtimes. Maybe that was their crappy plan all along?
