The 105 2-cable universal quad light unit is recommended for any situation that requires the action-stopping ability of short flash duration coupled with plenty of power. The 105 2-cable is constructed of aluminum, has forced-air cooling and two standard power cables, which allow up to 4800w/s of power to be used with its four 2400w/s plug-in vented flash tubes. It also includes a bright 250w quartz model lamp and protective tube pouch.
