I have two Venca flash units- - one 1200 watt-second and one 2400 ws. Each has 3 flash connections which can be used separately or combined for maximum power. These units haven't been used for several years (I am semi-retired, no longer using a studio location) but worked fine until put into storage. The flashes offer great control (from 25 to 1200 ws and 50ws to 2400ws) and have performed beautifully in my (former) studio.
