A system comprising track-mounted luminaires and track. In some embodiments, electrical power for illumination is accessed by a luminaire through electrified railing recessed within a relatively narrow slot of the track. In some embodiments, a mount is provided separately from and/or additional to the power slot; for example, a magnetic mount. Optionally luminaires are orientable to select a direction of illumination, while secured by the magnetic mount. The track is optionally mounted flush and/or recessed with a mounting surface such as a ceiling and/or wall. In some embodiments, a recessed surface of the track is formed with an arc. Optionally luminaires conform with the curvature of the arc. Additionally or alternatively, the track is at least partially masked and/or decorated, for example by plastering and/or a face plate.

A luminaire (61) is disclosed with a close coupled ballast (62) having a support arm (66) from which is suspended or hung a reflector, and preferably a variable focus reflector (41), having either a single ended lamp (3) or double ended lamp (23). The luminaire (61) is supported from a greenhouse rafter (9) by filaments (10, 11) which are connected one to the ballast (62) and the other to the free end of the support arm (66). In one embodiment the arm (66) is connected to a rigid side plate (64) which is mounted on the ballast (62). In another embodiment the arm (66) is connected to a side plate (164) which is hinged. The arrangement enables flimsy reflectors (41) to be close coupled with electronic ballasts in a way which minimises Radio Frequency Interference (RFI).

A light disconnect system has a base that affixes to a ceiling of a structure, such as a house or other building. The disconnect system includes a removable center that is received by and can affix to the base. The base has at least two receivers that mate with tabs that are located on the center. The receivers have a slot portion adjacent to a ledge portion which is adjacent to a contact portion. The contact portion has an electrical contact that faces upwardly. The contact is electrically connected to the structure's wiring. The tabs on the center have electrical contacts that face downwardly. To install the center, the user inserts the center into the base and rotates until it stops. The user then allows gravity to lower the center, which puts the electrical contacts on the tabs to make electrical connection to the electrical contacts of the base.

A lighting device, in particular suitable for being embedded in the ground, comprising an external appliance body, of a substantially cylindrical shape, comprising a bottom wall and a side wall which extends from said bottom wall. A lighting source attached to said bottom wall of the external appliance body and suitable to emit a beam of light with a main axis (X), towards a lens suitable to focus said beam of light. Lateral translation means are also provided for suitable to cause a translation of the lens on a lens plane orthogonal to said main axis so as to offset the center of the lens from said main axis, and rotation means suitable to cause a rotation of the offset lens on said lens plane around said main axis.
