NEW Arri ARRIMAX 18/12 Head

The NEW Arri ARRIMAX 18/12 Head is a high-output HMI lighting head built for film and TV sets that need maximum punch with controllable, clean beam shaping. The original Academy Award-winning ARRIMAX remains the ultimate choice for productions requiring maximum light output. The 580 mm (22.83”) diameter, parabolic facetted reflector provides continuous focus adjustment from 15° to 50° beam angle and, since the ARRIMAX does not require a set of spread lenses, shadows are sharp and easily cut.

Beam Control and Shadow Quality

The lens-less design and facetted parabolic reflector are designed to deliver an arc-like shadow quality that reads naturally on faces and set pieces, while still giving crews the ability to shape and cut light precisely with standard grip tools. Continuous focus adjustment from 15° to 50° supports everything from wider coverage to a tighter, more directional look without swapping spread lenses.

Lamp Support and Faster Re-Lamping

18,000W Single Ended lamps use a sturdier GX51 lamp base for which ARRI engineers have designed a special lampholder. This new lampholder alleviates mechanical stress from the lamp pins, which now serve only as an electrical connection. The lamp clamping mechanism is self-aligning and uses a rugged, recessed lamp lock handle. To ensure that crews can easily use 12,000 W lamps or versions of 18 K Single Ended lamps with G38 bases, the new lampholder accepts either lamp type with no modification or adjustment required. Easy re-lamping is supported via the EZ lamp lock system, and ARRI Dual Pin Width support (GX51/GX38) helps keep the head flexible across lamp inventory.

Designed for High Output, High-Heat Workflows

With ARRI eXtreme cooling, the ARRIMAX 18/12 Head is engineered for demanding shooting days where sustained output and dependable thermal management matter. For crews comparing output, it is specified as 50% brighter than a 12 K PAR, making it a strong choice for large throws, big diffusion, and exterior push-through setups.

Reflector Options

• Standard reflector: 15° to 50° continuous beam angle
