ARRI‘s M18 HMI Lamphead (110/220 VAC) is a newly designed, more efficient lamp head built to work with a new power class of lamp: the 1800W SE HMI (not included), which has an average life of 750 hours, a luminous efficacy of 92 lumens/watt, and a Color Rendering Index (CRI) greater than 90 at 6000K. The M18 is an open-face, lensless fixture that combines the characteristics of a PAR and a Fresnel, creating diverging rays of light to produce a very crisp shadow. It can operate on a 20A circuit. This lamp has a beam angle (HPA) of 20 to 60° with a wide usable field angle. The lamphead is silver.
This is an ARRI Head to Ballast Cable. The 50′ (15.2 m) long cable is compatible with 575, 1200 and 1800W heads such as the ARRISUN 5, 12 Plus, 18, and 40/25 heads. It’s also compatible with the ARRIMAX M18, the ARRI X X5 and X12, D5 and D12 Fresnels and the Compact 575 and 1200 heads.
