Item description: The Broncolor Verso A2 Power Pack is the ideal lighting solution for studio and location photographers, as it can use an alternating current or battery source. It combines high output power and short loading time and is characterized by a robust, reinforced aluminum and hard rubber construction for additional durability and protection during transport. The A2 offers a power control area of no less than seven aperture levels via practically the entire power range of the system (1200J to 9J). This in turn corresponds to a contrast ratio of 1: 128 and offers the photographer many creative lighting options and fine control. In addition, the properties and the contrast of the installation light match when using the strobe of the system exactly with those of the final image. Al.
