3W Zoom Flashlight IR Infrared Night Vision-Ghost Hunting Torch This is a very specialised infrared (IR) illuminator in the form of a neat hand held flashlight. It can also be used as a stand alone IR light or mounted on a camera rig. We have chosen this particular model as it runs from 1x regular AA battery (not included) The light has an array of 3 IR led chips that are mounted behind a movable glass lens allowing for wide or zoom narrow beam use. Infrared is a popular lighting format for Ghost Hunting/paranormal investigation as it is outside the human vision range allowing the location to remain totally dark while still being able to see clearly through the night vision cameras. Depending on the light sensitivity of the camera used, this torch light can illuminate to around the of range 10 m to 15 m. The infrared light spectrum is around 850nm, this wavelength of light is visible to the naked eye ONLY when looking directly at the led's and shows as a deep dark red. The light ray produced however is invisible to the naked eye and can only bee seen using night vision IR or full spectrum cameras or viewing devices. A great pocket sized self powered IR lighting option that can be used singularly or in multiples. Please Note! This light is for use with camera's that have infrared night vision,the light is invisible to the naked human eye Color: Black, 6061T Aircraft Aluminum Construction, Magnifying Abs Lens, 3 X /850Nm Ir Led Chips.Torch size Size 10 cm x 2.5 cm
