ProTungsten Air is a continuous light source, which is dedicated to work with most existing lines of Profoto’s Light Shaping Tools. ProTungsten units can be used with 500W or 1000W halogen lamps and are equipped with a state of the art cooling system, which is designed to minimize noises. In addition, the unit has a built-in “Air” radio remote capability, which gives the user to activate or deactivate and dim from 100% down to 10% of the light at the palm of their hands.
