A lighting device assembly includes a light source attached to a heat sink member, a first optic device and a mounting housing configured to be secured in or to a ceiling, wall or other object, and to hold the heat sink member. A second optic device including a second optic member is configured to receive light emitted in a first direction from the light emitting surface of the first optic device and to emit light in a second direction that is transverse to the first direction. A connection mechanism selectively connects the second optic device to the mounting housing, for selective disconnection from the mounting housing.

A grow light for stimulating plant growth is presented herein. The grow light includes a plurality of primary light modules with LEDs fixedly mounted to a support assembly and spaced a distance away from a plant canopy, and one or more secondary light modules movably or pivotally mounted to an end of one or more of the primary light modules. A positioning assembly is disposed interconnected light modules for manually or automatically movably disposing the secondary light modules into different angular positions relative to the plant. A height adjustment assembly is also include to movably position the light assembly, such as the plurality of primary light modules or the secondary light modules in a vertical direction. Additional features can be included, such as positioning sensors, environmental sensors, CO2 delivery systems, water cooling systems, ground wire interconnections, and light frequency control.

A lighting device, for attachment to an object structured to be worn on at least one facial feature of a human user, having a releasable fastener adapted for attachment to the above-noted object and a pole, having a first end pivotably connected to the clip, and a second end, opposed to the first end. An electric lamp is pivotably connected to the second end. Further, the pole defines an internal cavity and has battery contacts positioned to contact a battery set placed in the internal cavity. A conductive assembly is electrically connected between the battery contacts and the electric lamp, so as to power the electric lamp.

Devices for mounting objects on space frame truss or other structural members are provided.

An illumination system includes a light assembly. The light assembly may include a housing having a first zone and a second zone isolated from the first zone. The housing may be configured to fit generally flush with a ceiling. A movable light source may be positioned within the first zone and is configured to emit a first light. A stationary light source may be positioned within the second zone and is configured to emit a second light.

A luminaire arrangement for providing lighting in or near buildings. The luminaire arrangement may contain one or more of the following components: (i) at least one portable luminaire, which has a body and a lamp arrangement, (ii) at least one energy store, which is connected to the luminaire, is rechargeable, and is designed to supply electrical power to the lamp arrangement of the luminaire; and (iii) at least one charging device, which is designed to recharge the energy store. The energy store is attachable by means of an interface arrangement to the charging device in order to at least one of recharge the energy store and supply power to the lamp arrangement. The energy store is separable from the charging device in order to take the luminaire as necessary to any target location to be lit.
