The ARRI M40 HMI is a location work horse. Whenever you need to punch light through a silk or bounce light off a reflective surface, an ARRI HMI is the ultimate answer. At the design stage, the interaction of lamp, reflector and converter lens was taken into consideration and computer simulated, resulting in unmatched performance. The M40 can be fitted with a 2,500 or 4,000W single-ended HMI lamp, making it a very versatile lighting fixture. A wide range of converter lenses is available to ensure maximum beam control in all situations.
