The ARRI Arrisun 18 PAR With ALF/DMX Ballast Kit (120/220VAC) is an all-in-one lighting kit that includes a PAR fixture that accepts a 1200W or 1800W SE HMI lamp (not included) and can operate from a single 20A 120VAC electrical outlet--making this light not only very efficient, but also highly versatile. The 1800W SE HMI lamp (not included) has an average life of 750 hours, a luminous efficacy of 92 lumens/watt (L/W), and a Color Rendering Index (CRI) greater than 90 at 6000K.
