The newest top-of-the-line Flux headlight continues the Flux tradition of optimal beam pattern, wide variety of mounting options, and super rugged construction. Compared to the Flux 1200, the Flux 1250 increases lumens and runtime, throws in the helmet and camera-style mounts, while dropping the price. BOOM! Mode Shift user interface gives you three steady modes for just the right mix of lumens and runtimes to match riding conditions. Press-and-hold to enter the secondary modes, where you will find a Steady Flash mode for increased visibility in urban conditions, a Flash mode for daytime use, and 10 and 20 hour flashlight modes for bikepacking conditions, or when you forget to recharge and need to maximize the last few percent of battery life. 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.
