The 28 x 28" Westcott Apollo is a softbox based on an umbrella frame fabricated from fiberglass for added durability. It needs no speed ring to attach it to a flash head. Simply open it, and slide the shaft into the umbrella receptor on the flash head or the umbrella swivel supporting your speedlite. A lightweight reflector plate may be purchased separately to produce indirect lighting.
The 28" Apollo can be used with flash, fluorescent sources or hot lights up to 500 watts.
