The Impact Soft and Natural 4-Socket 3-Light Kit was put together to help image makers who need a lightweight setup for a wide variety of subjects. The three included Impact 4-Socket Fluorescent Fixtures accept lamps up to 50W and have built-in tilting brackets and 5/8″ receivers for the included 6′ light stands. Instead of a speed ring, these lights have four receptacles around the head that accept the poles from the included 20 x 27.5″ softboxes. The kit includes 12 digital-friendly CFL fluorescent lamps with E26 screw-in bases and a daylight temperature of 5000K. It all fits in the provided nylon carry bag.
