The M18 is an 1,800 W open face 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 extremely powerful lamphead, 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.
