ARRI 400/575W High Speed Electronic Ballast with ALF/DMX, 1000Hz

The Arri 400/575W High Speed Electronic Ballast with ALF/DMX is designed for use with Arri 400W or 575W HMI luminaries for high-speed photography at 500 to 5000 frames per second and includes DMX remote control--the ballast is set to 1000Hz rather than the typical 75Hz. It also uses ALF (Active Line Filter) which greatly increases the power efficiency of the light. Necessary for many applications such as sports, commercials, ballistics and material testing, auto component testing and industrial projects.
