ARRIMAX – the ultimate choice for productions requiring maximum light output. Combining the variable beam spread of a Fresnel with the light output of a PAR, the ARRIMAX uses a unique reflector concept for beam control that eliminates the need for spread lenses. The 580mm (22.8”) diameter, specular, flatted reflector can be adjusted to provide continuous focus from 15° – 50° 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 12,000W lamps or versions of 18K Single Ended lamps with G38 bases, the new lampholder accepts either lamp type with no modification or adjustment required.
