ARRI M18:
The ARRI M18 is an 1,800 Watt open-face lamp head that has redefined lighting in the film industry. It combines the Academy Scientific and Engineering Award-winning lens-less optical technology of the ARRIMAX with the innovative True Blue design. The result is an extremely powerful lamp head, as small as a 1,200W PAR but with a 70 % higher light output. The M-Series M18 fixture is adjustable from 20° to 60° without requiring spreader lenses. ARRI M18 is a newly designed, more efficient lamp head built to work with a new power class of lamp: the 1800W 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 6000K. The M18 is an open-face and lensless fixture that combines the characteristics of a PAR and a Fresnel, creating diverging rays of light to produce a very crisp shadow. It can operate on a 20A circuit. This lamp has a beam angle (HPA) of 20 to 60° with a wide usable field angle. The lamp head is silver. 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.
