    Abstract: An illustrative light fixture includes an emitter housing and airflow cooling channels. The airflow cooling channels are defined in the space between opposite edges of the emitter housing and a rim around the periphery of at least the opposite edges of the emitter housing. The airflow channels are further defined by fins spanning between the rim and opposite edges and spanning across a side of the housing opposite the illumination side.

    Abstract: A light fixture includes a central housing, a panel, a light source, and a tether. The central housing defines first and second side surfaces and a bottom surface, and the bottom surface defines a plane. The panel is pivotably coupled with the first side surface, and the light source is coupled with the panel. The tether is coupled at one end with the panel to pivotably suspend the panel, and the second end of the tether includes an attachment member. The attachment member is configured to selectively couple with any one of a plurality of anchor positions located on the central housing. The panel is therefore fixable between a plurality of angles relative to the plane as determined by the attachment member being coupled with a selected one of the plurality of anchor positions.
