•The Flashpoint M series allows you to choose AC and or DC powered operation (FP2PP, DC power pack sold separately). • Flashpoint Monolights are designed with the latest in high-tech features. They are compact, lightweight and deliver the performance that gives you a definite competitive edge. All at a fraction of the cost of heavier power pack units. Monolights are self contained, they do not require being hooked-up to a central power pack. That means no more wires winding throughout the whole studio. They have variable flash power settings,a flash-ready indicator and a built-in slave.
