The 43" 3-in-1 Compact Umbrella is a groundbreaking addition to both the LumoPro line and the photographic industry. Outfitted with white shoot through, white bounce off and silver bounce off options, this umbrella is designed to be versatile and compact. The umbrella's convertible cover can be removed for white shoot through lighting, reversed for white bounce off lighting, or inverted into the umbrella using the rib hooks to use for silver bounce off lighting. Each style changes the way light is shaped and offers a variety of applications in photography. The LP735's shaft is standard and designed to fit the LP633, LP679-1, or LP634 umbrella swivels. This umbrella is not compatible with smaller shaft holes as seen on Profoto, Elinchrom, and Strobe Light brand products. Diameter (Measured Concave): 43 inches Height (Collapsed): 15 inches
