Serious road riders put in serious miles. Most of those miles occur in the daytime, when bright ambient conditions mean you need huge lumens numbers to be seen by motorists. But there's no reason a super-bright taillight can't look the part on the fastest road bikes. You invest in the best road bike technology--you deserve an equally fast taillight. Packing a huge punch with 250 lumens, the Flux 250R taillight is visible at more than 1 mile (1.5 km) in the brightest daytime conditions. Here in Morgan Hill, California we get those conditions all the time, this is the taillight we made for ourselves, and for you. - Designed to fit round and D-shaped seatposts. - Disco Flash mode: 250 lumens for 8:00 hours - Eco Flash mode: 25 lumens for 60:00 hours - Hybrid spherical lens and Fresnel lens over three high-power LEDs to send lumens for mile, or kilometers. - IPX7 waterproof means this light will be there when you need it, even in the hardest rain. - Includes 3 different size EPDM o-rings to fit a wide variety of seatposts. 2 o-rings included per size for spares. - Massive 1000mAh battery recharges via included micro USB cable in 2:15 hours. - Overmolded bezel for excellent side visibility. - Power Flash mode: 250 lumens for 8:00 hours - Steady High mode: 100 lumens for 3:00 hours - Steady Low mode: 25 lumens for 12:00 hours - Three CREE XBD 901 LEDs for maximum brightness and efficiency.

Splitting the difference between the previous Flux 800 and 900, the Flux 850 gets the game-changing Mode Shift found on the Flux 1250. This means there are three steady modes, all using both the wide and spot beams. Go from Steady Low to Steady High in a single push, without cycling through a flash mode. Press-and-hold for two seconds and you get into the secondary modes: Steady Flash to be seen in busy urban environments, Flash Mode for endless runtime, and two Flashlight modes with 10 and 20 hours of runtime for hanging around the campsite, or when you forget to charge your light and need to conserve the last few percent of battery life to get home. IPX7 waterproof means this light can survive being submerged 1 meter deep for 30 minutes. No, it's not meant for scuba diving. But is can handle anything you can throw at it on two wheels. - Sculpted double beam pattern uses separate optics for wide and spot beams to put light where you need it and maximizes every lumen. The result is a beam pattern that torch-style lights can't touch. - 1x CREE XP-L High Intensity LED plus 1x CREE XP-G LED. - Quick-release bar mount works on 22.2, 25.4, and 31.8mm bars to put the light above, below, or in front the stem to clear cables and computer mounts. - Extra bright side lights to give you 180-degree visibility to other cyclists and motorists. - 2600mAh Li-ion internal battery is USB rechargeable via included micro USB cable. - Depending on mode, up to an additional three hours of super-low output are available when listed runtimes expire.
