With a 200 lumen output, the lightweight (66 grams) Volt200XC is a solid option for riders looking for the perfect combination of lumen output, weight, and price. The USB-rechargeable Li-ion battery provides 20 hours of flashing light, 10 hours of low light, or 1 full hour of high power lighting. The secure rubber hook closure is easily removable so you can keep the light in a riding jersey or commuter jean pocket during daylight hours. The on/off switch doubles as a battery indicator light, so you know when the battery is running low on power. Click here for The Volt 200 Manual. The USB-rechargeable Rapid mini offers 4 modes of eye-catching illumination.
