The ARRIMAX 18/12 was introduced in 2005 as the most powerful HMI on the planet, capable of being used with either 18 kW or 12 kW bulbs. Since then it has become a firm favorite of top international gaffers and cinematographers, and is relied upon all over the world by productions requiring maximum light output and rugged build quality.
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.
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. In 2009 the designers of the ARRIMAX were honored with a Scientific and Engineering Award from the Academy of Motion Picture Arts and Sciences (AMPAS).
