The WhiteDome™, which comes with the Lightsphere® Universal™ and Collapsible™ product lines, allows you to reduce the amount of light ommited from the top of your Lightsphere®. This is ideal in low hanging ceiling environments where the bounce light is too strong.
ALSO: To achieve an accurate white balance in mixed lighting, use the WhiteDome™ to take a custom reading. Produce professional results with a tool you already have on-hand or add another to your gear bag for quick balancing on the go.
I'm sorry the postage to your area was expensive. The postage options are available on checkout, and some are slow/inexpensive, and some are really expensive and still too slow. We will have some on Amazon (we are the only merchants on Amazon that sell my products), and if you are a prime member, you can save the shipping. Our prices are less though.
