The Ultratec Nightjar is a rechargeable light from Ultratec, the South African lighting brand, supplied here in blue. As a rechargeable unit it saves you buying disposable batteries: charge it up and keep it ready for load shedding, camping trips, the car cubby or the bedside drawer. Ultratec makes practical, everyday lighting for homes, farms and outdoor use, and the Nightjar fits into that range as a handy grab-and-go light. We could not find a published specification sheet for this exact model, so check the packaging for the light output, battery capacity, charging method and runtimes before relying on it for a specific job.
