This is the Impact Two Monolight Softbox Kit (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 3 - 4 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 2 monolight kit includes air cushioned light stands, 24 x 32" softboxes, and sync cord (Mini plug to PC).
