Rando is designed for extended adventure perfect for dynamo setups, touring, commuting, and off-grid riding. Featuring all of the safety innovations of the Urban series, the high capacity lithium ion battery has enough juice to power the light for a full 3 hours on high and a mighty 24 hours in daytime pulse mode! For those that find themselves on extended adventure, Rando is the first high-visibility bike light that allows the light to trickle-charge while in use. Perfect for dynamo setups with a USB charger or an external battery pack, cyclists can now rely on powerful safety lighting even if conventional charging is unavailable. Reliable construction is a prime consideration for extended rides and Rando’s waterproof lighting platform has a certified IP67 rating – meaning the light is certified to withstand water immersion up to a depth of 1 meter. Ride with the added assurance knowing rain or shine the light will keep performing. Whether competing in endurance racing, bike packing across the country, or commuting over 3 hours a day with no place to recharge – Rando is the ultimate long runtime lighting solution.
