Multipurpose flashlight with dual red LEDs and dual white LEDs, for night vision projecting red light or regular white light, both easily controlled by a switch. A convenient control wheel allows you to adjust the brightness setting for just the right amount of illumination you need. The casing is constructed with a durable plastic and includes a neck strap. Includes a standard 9 volt alkaline battery, which under normal usage will run for many hours. The total weight with the battery is only 4oz. Slightly tapered design from front to back, but maximum dimensions are approximately 5"x1.5"x1.5". Same product as sold under other brand names for a lot more, although our current stock does not have any brand name imprinted on it.
