Westcott has listened to photographers and has carefully constructed a new line of high-quality 500watt softboxes. The Westcott Pro series is a perfect fit forphotographers utilizing compact fluorescent, LED or low-wattage strobes.
That may vary depending on the specific light unit. Generally speaking, most lights for photo and video use have a receptacle for the standard 5/8" stud found on most light stands. Softboxes normally require a speed-ring specific to the make/model of the strobe in order to mount them to a light.
