1800w HMI PAR - Arri AS18

  • as18-2.jpg
  • m18-3.k.jpg


The AS18 is an 1800w PAR style lamphead, combining industry-standard ARRISUN features with the innovative True Blue design. The result is an exciting new class of HMI, as small as a 1200w PAR but with a 70 percent higher light output.

The use of an 1800 W lamp is made possible by the patented True Blue Cross cooling system, which maintains airflow at any tilt angle. This keeps all parts of the fixture within safe working limits.

The AS18 uses the same lenses, cables and accessories as the former ARRISUN 12, and has similar beam spreads. For compatibility, the lamphead can even be used with a 1200w lamp and powered by either the purpose-designed EB1200/1800 or any ARRI 1200w ballast.
