While 71" Silver Shallow Umbrella 180 was designed for NanLite P-series monolights, but its 8mm shaft makes it compatible with most LED, strobe, and constant light fixtures. The light source can be slid anywhere along shaft to focus and de-focus the output to vary the umbrella's very wide coverage that makes it ideal for large groups, expansive spaces, or to increase the ambient light level. The modifier has a rigid 16-rod design and that delivers an even, wrap-around look, while highly the reflective silver interior offers a snappy, contrasty quality of light that can be thrown a considerable distance.
