Diffuser for 155cm Aurora umbrellas. Optional diffuser cover turns the umbrella into an affordable and extremely portable 'softbox'. Aurora umbrellas together with diffuser produce soft and wrap around lighting that is perfect for single light portraits. Thanks to a draw-string, UD-155 is usuable with or without reflector. Just put the light in the centre hole of UD-155 and pull the draw-string hard around for no light spill.
