This is the Impact Two Monolight Kit without Case (120VAC).
Each basic monolight in this kit has a digital readout coupled with its four-stop power variator. It accepts Bowens monolight reflectors and head accessories. The VSD160 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.
The Impact VSD160 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, white umbrellas, and sync cord (Mini plug to PC).
