The HYDRACELL™ Aqua Tac Flashlight / Lantern is a compact aluminium combination LED flashlight and lantern powered by a proprietary water activated HYDRACELL HC1D battery fuel cell. HYDRACELL battery fuel cells last up to 32 times longer than leading alkaline disposal batteries. Biodegradable and recyclable HYDRACELL’s battery fuel cells are a better choice for a smarter, cleaner and more sustainable future. A bright, long-life Cree LED provides an intense, focused beam of light in flashlight mode and 360 degree light in lantern mode. A focal head provides both area light and a focused beam. Ideal for everyday use, survival kits, or emergency situations. Simply activate the HYDRACELL battery fuel cell in water for hours of light.
