The M18 combines MAX Technology, True Blue features and a new 1800 W lamp. The result is an exciting new class of HMI that can be powered from most domestic sockets. It is as small as a 1200 W PAR lamphead but with 70% higher light output. The M18 can also be used with 1200 W lamps.
The Arri M18 HMI Lamphead (Sliver) is an open-face, lensless, more efficient lamphead built to work with a new power class of lamp - the 1800 W SE HMI (not included), which has an average life of 750 hours, a luminous efficacy of 92 lumens/watt and a Color Rendering Index (CRI) greater than 90 at 6000 K. DMX control and ALF (Active Line Filter) together produce much more efficient power use in an already very efficient lighting fixture. The M18 combines the best aspects of a PAR and a Fresnel, creating diverging rays of light to produce a very crisp shadow. This fixture is supplied for use with 90-125/180-250 V AC. This lamp has a beam angle (HPA) of 20 to 60 degrees, with a wide usable field angle.
