This is a Westcott Apollo Speedlite Kit based on the 28" Apollo umbrella style softbox. The 28" Apollo light modifier allows you to scrim or control the light more readily and allows for 104° of light spread. Built on an umbrella frame, this unit requires no adapter ring and opens and closes just like a standard umbrella, allowing for quick set up and tear down. Pairing this unit with Westcott's #5015 Shoe Mount Umbrella Bracket offers an ideal set up for speedlites. Insert your shoe-mount flash directly inside the Apollo, rotating the head of the speedlite towards the back of the Apollo, and achieve an indirect (evenly distributed) beautiful light source.
