ARRI M18 HMI Lamp Head, Blue/Silver

The M18 is an 1,800 W open-face lamp head, combining the innovative True Blue design with the Academy Scientific and Engineering Award-winning lens-less optical technology of the ARRIMAX. The result is an extremely powerful lamp head, as small as a 1,200 W PAR lamp head but with a 70 % higher light output. The M-Series M18 fixture is adjustable from 15 Degree to 58 Degree without requiring spread lenses.The use of an 1,800 W lamp is made possible by the patented True Blue Cross-Cooling system, which maintains airflow at any tilt angle. This keeps all parts of the fixture within safe working limits.
The M18 uses the same accessories and cables as the ARRISUN 12; it can even be used with an 1,200 W lamp an powered by either any ARRI ballast supporting 1,200 W power class. Using the M-Series M18 with ARRI electronic ballasts ensures maximum output and no decreased color rendition even at high frame rates. The included CCL (Compensation of Cable Losses) system maintains full power to the lamp even when using Head-to-Ballast cables up to 100 m (330 ft) length.The M18 innovations include the stainless steel friction disc, which locks the lamp head securely even when using the largest Chimera.

An alternative to the separate frame with screens is the frosted glass, which ensures an almost perfect homogeneity of the light field.It is also possible to convert the M18 to lens operation by fitting an ARRISUN style conversion kit and adding ARRISUN 12 or AS 18 lenses, giving a 6 Degree to 65 Degree beam spread.
Maintenance and repairs are easier with fast, simple access to all internal components. The M18 is IP23-rated weather resistance and withstands even driven rain.The 1,800 W power of the M18 is designed to work in offices and domestic situations without the need of a generator. Drawing less than 13 A (230 V-) resp. 20 A (120 V-) it can run on most domestic sockets around the world. It is the perfect daylight fixture to keep in the back of the car.
