Abstract

A lighting device, system, and method are disclosed. The lighting system includes a connector configured to be coupled with a relatively stationary object. The connector may have a first coupling face. A light source support may be configured to support a plurality of light sources. The light source support may have a second coupling face configured to mechanically and electrically couple with the first coupling face. The second coupling face may be radially symmetric and able to couple with the first coupling face in a first orientation and in a second orientation. The second orientation may be substantially opposite the first orientation.

Claims
