Arri M40 – High-Performance 4K HMI Light

The Arri M40 is a powerful 4,000W HMI daylight fixture that is part of Arri’s renowned M-Series, combining the benefits of PAR and Fresnel lighting into a single, efficient unit. Thanks to Arri’s MAX Technology, the M40 eliminates the need for traditional spread lenses, delivering an exceptionally even light field while maintaining high output and flexibility. The fixture’s rugged design and weather-resistant construction make it an industry standard for professional film, television, and commercial productions.

Power & Performance

The M40 delivers an impressive light output with excellent beam control. It can be focused from 18° (spot) to 52° (flood), allowing for precise illumination without the need for additional lenses. Its highly efficient reflector system ensures maximum brightness with optimized energy use, making it ideal for both studio setups and on-location shoots where powerful daylight sources are required.

Light Shaping Options

The Arri M40 can be customized with various light shaping accessories to fit different production needs:

• Barndoors: Allow precise shaping of the beam, controlling spill and defining the spread.
• Softboxes & Diffusers: Transform the M40 into a large, soft light source for beauty shots and natural-looking illumination.
• Chimera Lightbanks: Ideal for creating soft, even lighting while maintaining high efficiency.
• Scrims & Nets: Reduce intensity without altering color temperature, providing subtle adjustments to exposure.
• Reflectors & Bounces: Modify and direct the light for more creative control on set.
