ARRI M18 1800 Watt HMI
These HMI units combine the variable beam spread of a Fresnel fixture and the light output of a PAR fixture. They use a unique mulit-faceted reflector that eliminates the need for spread lenses. These powerful units in various power classes produce a shadow quality that is crisp, clean and sharp.
Based on the design principles of the ARRIMAX, the M18 is an innovative lamphead that works with a new power class of lamp: the 1800W SE HMI™. This lamp boasts 750 hours of average life and a Luminous Efficacy of 92 Lumens per Watt (L/W). The Color Rendering Index (Ra) is greater than 90 at 6000K (CCT).
Now the "Brightest HMI you can plug into the wall,"* the M18 is a lensless, open face lighting fixture that combines the desired light distribution from the optics of a PAR and a Fresnel fixture. The unique ARRIMAX reflector design creates diverging rays to produce a crisp shadow.
With a beam angle (HPA) of 20 to 60 degrees and a wide usable field angle, the M18 is designed to be both intense, efficient, highly versatile and meet better lighting efficiencies in a new performance class.
