Frequently Asked Questions
What is the diameter of this umbrella when fully opened?
The Westcott 4633 opens to a full 7-foot (84-inch) diameter, providing a very large light source for wrapping, flattering illumination.
What does the included black cover do?
The removable black cover converts the umbrella from a reflective silver modifier into a contained light source, blocking spill and giving you more directional control over where the light falls.
What shaft size does this umbrella use?
It has a 7mm shaft tip, which fits standard umbrella mounts on most studio strobes and continuous light heads.
How durable is the frame in windy on-location conditions?
The 16-rib fiberglass framework is designed to flex rather than snap, making it more resilient than metal-ribbed umbrellas. However, at 7 feet, a sturdy stand and sandbags are strongly recommended outdoors.
Does it come with any carrying solution?
Yes. Westcott includes a travel and storage case for transport and protection.
