No, unfortunately, two lamps cannot be hung on the Lightswing® Single. The Lightswing® is assembled and closed on one side, so a Quick Release cannot be attached to this side, and therefore no second lamp can be attached. If you still want to be able to alternate between 1 or 2 pendant lamps, it is best to choose a Lightswing® Twin. Both 1 and 2 pendant lamps can be attached to the Lightswing® Twin.
