The ELB 1200 Hi-Sync Flash Head from Elinchrom is one of 3 flash heads redesigned for use with the ELB 1200 battery-powered pack. If you're using High-Speed Sync to control ambient light, freeze action or to use wide apertures for shallow depth-of-field, the Hi-Sync head is for you. When combined with the separately purchased EL-Skyport Plus HS Transmitter, shutter speeds as short as 1/8000 sec are possible. 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 Hi-Sync Flash Head has a 5/8" receiver for light stands and will accept both 7 and 8 mm umbrella shafts.
