Princeton Tec Eos Bike Headlamp Light





The Eos Bike is the ultimate waterproof commuter. 3 levels & a flash mode in impact-resistant housing with a regulated Maxbright LED.

The Eos Bike light takes self-contained battery lighting to the next level. The combination of a Luxeon(R) 1-watt LED and the Princeton Tec-designed optimized lens/collimator maximizes the beam by balancing long-throw with localized lighting. Recognizing that different amounts of light are needed for different riding conditions, Princeton Tec equipped the Eos with three brightness levels and a blinking mode; further ensuring that the Eos will remain at Constant Brightness as long as the batteries have sufficient voltage. The use of high-grade materials ensures durability and strong resistance to water/weather/environment conditions.
