The 2 in 1 Water Safety Light is both a high powered flashlight and a lantern that will float on top of the water! The water resistant flashlight is ideal to use in the rain or when boating. If this light were to fall in the water, it would float on the surface and continue to operate. With the turn of a lever the flashlight can be instantly converted into a lantern. Great for camping or to use during a power outage. Requires four "AA" batteries.
