The M18 is an 1800W ARRIMAX style lamphead, combining the Academy Scientific and Engineering. Award-winning lens-less optical technology of the ARRIMAX with the innovative True Blue design. The result is an exciting new class of HMI, as small as a 1200W PAR but with a 70 percent higher light output. The “BABYMAX” gives a remarkably even beam spread that casts crisp shadows and is adjustable from 20-60 degrees without requiring spreader lenses.
