The Impact Soft and Natural Single Socket 2-Light Kit was put together to help image makers who need a lightweight setup for a wide variety of subjects. The two included Impact Single Socket Fluorescent Fixtures accept lamps up to 105W and have built-in tilting brackets and 5/8" receivers for the included 6.0' light stands. Instead of a speed ring, these lights have four receptacles around the head that accept the poles from the included 20 x 20" softboxes. The kit includes two digital-friendly CFL fluorescent lamps with E26 screw-in bases and a daylight temperature of 5000K.
