Product Information:The Gimbal Ring Electronic Track fixture suspends down from the track. The ring on the end of the fixture can be manually rotated in a 360 Degree radius to display direct light to a specific area in the room, and it can be slightly bent from a vertical to a horizontal positioning. This effect allows the track head to be easily pointed into the desired direction, to get the most out of the lighting system.
