    Princeton Tec EOS Bike Headlamp - The EOS BIKE by Princeton Tec takes self-contained battery lighting to the next level. The combination of a Maxbright Rebel LED and a Princeton Tec-designed collimator maximizes the beam by balancing long-throw with localized lighting. The self-contained unit feels virtually weightless on your helmet and makes the ultimate backup light for your 24-hour race. The EOS BIKE is light enough to throw into your jersey pocket for a late afternoon ride ensuring you’ll have enough light to get home. It is drop proof and its use of high-grade materials ensures durability and strong resistance to water/weather/environmental conditions. Includes helmet, handle bar and headlamp attachments.

    I bought the Eos to replace a small Cateye light that I had used as a helmet light until it unexpectedly died on me. I commute by bike and I got over 3,000 miles of solid-on or flashing light from the Cateye, but I expected more. The Eos costs about the same as the Cateye unit and uses the same AAA batteries (I prefer AA for runtime, I'll put up with the weight - this is the only reason I didn't give the Eos 5 stars). However, the Eos' light is *bright* - nearly as bright as my 10-watt halogen main light. The runtime is quite good - I got over a week of commuting from the provided alkaline batteries before switching to rechargables. The light doesn't seem dimmer on the rechargables, unlike some other LED lights. The Cateye required some ingenuity to mount on my helment - the Eos comes with a proper helmet mount in addition to the handlebar mount. It's clear that the light was originally designed to be mounted on a headband, which is fine for me. The battery compartment is secured by a small screw with a knurled edge for grip, and seems reasonably waterproof. I've used it light rain with no problems and I don't expect the eventual downpour will cause any trouble, either.

    I have purchased four of these now. All for different bikes. All of them are fantastic, and more than worth the money
