This is the Impact Two Monolight Kit with Case (120VAC). The VSD300 has cushioned touch-pad function control buttons. Power is adjustable in 1/10 stop increments, from full to 1/8 power. Its model light intensity may be controlled coupled to, or independent from the strobe power levels you select. This kit provides ample power to light a three-four person full-length portrait.
The Impact VS300 is a good unit for occasional use by a hobbyist, or beginning professional. It is a good choice for building a system - its built-in optical slave fires the flash without wires, from the light of any other flash system. Its flashtube is good for tens of thousands of pops, and is replaceable.
This two monolight kit includes air cushioned light stands, 43" white translucent umbrellas, sync cord (Mini plug to PC), and soft padded case with shoulder strap and internal movable dividers.
