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.

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.
