The Freejack Round LED Canopy 277 Volt from Visual Comfort Architectural, formerly known as Tech, Lighting provides power (60W) as well as support for any 12V FreeJack pendant or head. Its rounded metal design houses an electronic transformer and sits flush over a standard 4” junction box or an octagonal electrical box (not included). Can be installed on the wall or ceiling, though, in the case of wall lighting, an attached head should have no more than a 6” extension.
