Unfortunately, two lamps cannot be hung on the Lightswing® Single. The Lightswing® is assembled and closed on one side, so an extra Quick Release cannot be attached to this side, and therefore, a second lamp cannot be attached. If you still want to be able to alternate between 1 or 2 pendant lamps, it is best to choose the Lightswing® Twin. With the Lightswing® Twin, both 1 and 2 pendant lamps can be attached.
