It's cute that the puppy is joining Barbie in her workout routine.
The actual light source consists of a curly lightbulb inside of a rectangular umbrella type frame. Then there is a white piece of diffuser fabric that attaches to the frame with Velcro. The frame measures 20"x27" (50.8cm x 68.58cm.) Neither Mr. BTEG nor I could find a way to turn the rectangle so the long side was at the bottom. I have to take care when I rotate the frame up or down, to make sure the frame's weight stays balanced.
This light stand wasn't as expensive as I thought it would be, so I'm glad I invested in something a little bit better to help my photography.
