About Arri

The Arri 125/200 W High Speed Electronic Ballast with ALF (1000 Hz) is designed for use with Arri 125 W or 200 W HMI luminaries for high-speed photography at 500 to 5000 frames per second - the ballast is set to 1000 Hz rather than the typical 75 Hz. 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.
