The 7" Umbrella Reflector fits around the flashtube and modeling lamp on the front faceplate of all standard Paul C. Buff, Inc. flash units. The wide-angle reflector directs all of the light directly out front, blocking any undesired side spill. The reflector additionally has an umbrella hole for use with our PLM™ Umbrellas and various brands of umbrellas and brolly boxes. When used with umbrellas, the reflector directs all light into the umbrella, eliminating side spill.
