Flux 250R Taillight - One Size

Serious road riders put in serious miles, most of which occur in daytime when bright ambient conditions demand high lumen output to be seen by motorists. The Flux 250R taillight delivers the performance and aesthetics that match the quality of modern road bikes, with 250 lumens of brightness visible at more than 1 mile (1.5 km) in the brightest daytime conditions.The light uses a hybrid spherical lens and Fresnel lens design positioned over three high-power CREE XBD 901 LEDs to maximize brightness and efficiency. An overmolded bezel provides excellent side visibility, ensuring you're seen from multiple angles.The taillight is designed to fit both round and D-shaped seatposts, with three different size EPDM o-rings included (2 per size for spares) to accommodate a wide variety of seatpost diameters. A massive 1000mAh battery recharges via included micro USB cable in 2 hours and 15 minutes, and the IPX7 waterproof rating ensures reliable performance even in heavy rain.Multiple brightness modes provide flexibility for different riding conditions: Steady High mode delivers 100 lumens for 3 hours, Steady Low mode provides 25 lumens for 12 hours, and Power Flash mode offers the full 250 lumens for 8 hours.
