Rotalux Strip softboxes are great for product photography, especially bottles and other round reflectives items. They can also be used for ¾ length portraits and also widely used to light backgrounds where the length helps avoid fall-off from top to bottom.
The easy mounting Rotalux system is probably the most widely copied of all Softbox systems. However, it is easier to copy a design than a quality and they remain the best units in their class.
