The Quick Release is a coupling device that allows you to attach the pendant lamp to the Lightswing®. The Lightswing® Single has 1 Quick Release, while the Lightswing® Twin has 2 Quick Releases. You can slide the Quick Release out of the end of the Lightswing®, regardless of whether there is a pendant lamp attached to it or not. With the Quick Release, you can easily hang up your pendant lamp, but also temporarily remove it.
