The ZOOM ACTION head offers unique super short flash duration with a user replaceable single, twin electrode flash tube to ensure even light distribution. Further this head offers a microprocessor controlled, low noise fan cooling system, a new included transparent glass dome, and a zoom function for the modeling lamp and flash tube, to obtain individual results when used with reflectors or a wide and even light distribution for Rotalux softboxes. The zoom function is accessible from both sides of the head housing. The new housing is rock solid and lightweight with a large rubberized handle.
