ARRI ARRIMAX 18/12 is an open-face HMI PAR lamphead built around lens-less MAX Technology. A facetted parabolic reflector in high-purity aluminium delivers a dense daylight beam without spread lenses, keeping shadow edges crisp and straightforward to cut. With the standard reflector, focus travels continuously from 15° to 50°, giving gaffers a single-source option for long-throw daylight key, hard backlight, or wide flood washes on large sets. Lens-less optics also remove the need for a spread-lens kit; beam changes happen at the focus control.

The head operates with single-ended metal-halide lamps at 18,000 W or 12,000 W. One lampholder accepts GX51 and GX38 bases; a self-aligning clamping mechanism and recessed lock handle stabilize the arc position while reducing mechanical stress on lamp pins during relamps. Correlated color temperature is approx. 5,600 K. With a compatible ARRI electronic ballast, intensity trims from 50–100%, and the specified voltage range is 225 V / 160 V (lamp dependent). Maximum surface temperature is specified at 240°C.

Paired with an EB MAX 12/18 or EB MAX 18/12 ballast, ARRIMAX 18/12 supports high-speed imaging through AutoScan square-wave drive up to 1,000 Hz, supporting flicker-controlled imaging at 1,000 fps and, in many configurations, beyond. Ballast options add professional set integration such as DMX control, while the lamphead can work with motorized yokes such as BigBee for remote pan/tilt in studio grids and condor rigs.

An IP23 rating and a mature accessory ecosystem—spot reflector (8° to 15°), 4-leaf barndoor, scrims, snoot, and head-to-ballast cabling—make the fixture practical for exterior day-for-night, stadium-scale toplight, large greenscreen keys, VFX plate acquisition, and industrial high-speed tests where stable photometrics matter. ARRI specifies safety clearances of 15 m to the illuminated surface and 2 m around the luminaire. IP23 supports work in light rain, sea spray and set atmospherics.

M-Series ARRIMAX 18/12 with MAX Technology - “The most powerful HMI light on the planet”
Lens-less system with MAX Technology - The Academy Awardwinning ARRIMAX remains the ultimate choice for productions requiring maximum light output. The 580 mm (22.8”) 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.

Safe and easy for both lamp type bases - 18 kW and 12 kW. 18,000 W single ended lamps use a sturdier GX51 lamp base for which ARRI engineers have designed a special lampholder that alleviates mechanical stress from the lamp pins, now serving 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 18,000 W single ended lamps with G38 bases, the new lampholder accepts either lamp type with no modification or adjustment.

The ARRIMAX 18/12 has a unique proven track record in numerous major feature film productions worldwide. Operated with the EB MAX 18/12 even worriless shootings for SFX, VFX, commercials, sports industrial applications, automotive component testing, ballistics or material testing are feasable.

The AutoScan technology supplies the lamp with a greatly raised 1,000 Hz square wave current and makes it easy to achieve high quality flicker free images even at frame rates of 1,000 fps and in many cases beyond even with a single source. Going along with the enormous light output the ARRIMAX 18/12 is part of an optimized lighting system in conjunction with the latest generation of electronic ballast and the specifically designed accessories, providing both versatility and maximum quality unreached.
