This is the Elinchrom ELB 1200 Pro Head [20187]

The Elinchrom ELB 1200 Pro Head is one of 3 flash heads redesigned for use with the ELB 1200 battery-powered pack. A great all-around head, the Pro has a short flash duration of 1/5050 with the power pack set at 140Ws. Featuring aluminum construction, the head conserves battery power with the use of a 50 W LED modeling light with a tungsten equivalent of 250 W. The lamp is daylight balanced with a high CRI of 92 allowing it to be used for video if desired. The lamp gets 80 minutes of run time with the standard ELB 1200 battery. The fan-cooled head has a Silent Video Mode for sound-sensitive venues. Modeling light settings include On, Free (user-selectable) Proportional (to selected power level), Dimming and a 1-60 second Timer. A VFC (Visual Flash Control) shuts down the light after exposure and turns it back on when the pack has recycled. The ELB 1200 Pro Flash Head has a 5/8" receiver for light stands and will accept both 7 and 8 mm umbrella shafts.
