The Ultratec Tri-Light is a three-piece rechargeable lighting set built around a lithium battery, with a combined output of up to 1000 lumens and a power bank function for topping up a phone. A set like this is useful during load shedding, when you can spread the lights between rooms, or on a camping trip where one light can go in the tent and another at the braai. Being lithium powered, it is lighter than older lead-acid lamps and holds its charge well between uses. We could not find a detailed specification sheet for this model, so check the box for runtimes and charging details. The supplier lists it as end of line.
