ARRI M90/60

To fill the gap between the M40.25 and the ARRIMAX 18/12 ARRI introduced the 9,000W M90 HMI Head. They’ve put it together with a 6/9K high speed ballast specially made for it with this M90 9,000W HMI High Speed Kit. Osram has created a 9K lamp for this power class that is nearly the same size as the 6K version allowing use of either lamp in the MAX Technology reflector and with the ballast. The highly stable 9K lamp is perfectly suited for high speed use up to 1,000 frames per second.

The M90 uses lens-less MAX technology to combine the characteristics of a Fresnel and PAR source. With a focus range of 16 – 49°, normally only achieved with supplementary lenses, the M90 performs like a traditional 12K with the compact form factor of a 6K head. Innovations like Cross Cooling separates the electronics from the lamp housing, thus ensuring greater longevity of the head and lamp.

The EB 6/9K High Speed Electronic Ballast with ALF and DMX has been streamlined and packed with features like CCL to compensate for power loss over long cable runs and Active Line Filter to counter electromagnetic interference. This version of the ballast allows high speed shooting of sports events, industrial applications, automotive component testing and ballistics or material testing without any concerns about flicker.

Since the M90 can accept either of Osram’s 6K or 9K lamps, the ballast features automatic detection of both lamps and lamp heads. There’s also a low noise mode and DMX on/off and 100-50% dimming control. To help you monitor the unit while shooting, it has LED indicators for input voltage, protective earth, over temperature, lamp on, detected lamp, and low noise mode as well as an illuminated on/off switch.

The kit also includes a set of 4-leaf barn doors and a 50′ head-to-ballast cable. The lamp is purchased separately.
