The Ultratec Stand-By 300 is the brighter version of Ultratec's rechargeable stand-by light, giving up to 300 lumens from a built-in lithium battery. It is made for load shedding and power failures at home, but works just as well on a camping trip, in a caravan or at the back of the bakkie. A rechargeable lithium light saves the cost of disposable batteries and is lighter than older lead-acid lamps, so it is easy to carry from room to room. Keep it charged and in a place where everyone can find it in the dark. Check the packaging for runtime and charging details.
