1. An illumination device comprising:

  • (i) a connector for connecting the illumination device to an Edison screw light socket or other standard light socket;

    (ii) an adjustable mount attached to the connector; and

    (iii) a luminaire module coupled to the connector via the adjustable mount, wherein the luminaire module comprises(a) one or more light-emitting elements (LEEs),(b) a light guide comprising an input end and an output end,(c) one or more primary optics positioned to receive the light emitted by the one or more LEEs and coupled with the light guide at the input end, the one or more primary optics adapted to at least partially collimate the light from the one or more LEEs and to provide the collimated light to the input end of the light guide, the light guide positioned to receive, at the input end, light from the one or more primary optics and adapted to guide the received light to the output end along a forward direction, wherein the light guide is elongated along a transverse direction orthogonal to the forward direction, and(d) a secondary optic elongated along the transverse direction and adapted to receive light guided by the light guide to the output end, the secondary optic having at least one redirecting surface, the at least one redirecting surface being adapted to reflect at least a portion of the light received at the secondary optic,wherein the adjustable mount is adapted to rotate the luminaire module relative to the connector.
