Profoto 100993 Umbrella Diffuser EXL 1.5 Stops

The Profoto Umbrella Diffuser (XL) is a simple accessory that is pulled over the front of a white or silver umbrella to turn it into a huge softbox, thereby creating a softer and more diffused light. Compatible with the Umbrella Deep White XL and the Umbrella Deep Silver XL, this diffuser reduces the output by 1.5 stops.
