Designed specifically to work with the Nova P300c RGBWW LED Soft Light (sold separately), the Aputure NOVA P300c Softbox increases the size of the light source to 27.5 x 20 inches, while simultaneously softening the output of the bright LEDs. This softbox slides securely into the fixtures accessory channel, and the front diffusion panel is easily removed so the softbox can be used as a large reflector. Control the fixtures beam angle with the 40 fabric light control grid, and safely transport everything in the included carrying bag.
