Princeton Tec

Whether you're a dedicated, year-round commuter or racing through the night, Princeton Tec's EOS is the light you want on you. It's equipped with a Maxbright Rebel LED that's super bright and balances long-throw with localized lighting. It's crazy light, so you barely feel it when mounted on your helmet or thrown in your jersey pocket. That lightness doesn't give up a thing in the durability department, it's fully waterproof and can survive a knock or 2. It's got 4 different modes, so you can tailor your lighting and the run times are epic: up to 121 hours. And the best thing is that the lighting is regulated, meaning no dimming, it's full on until it's off.
