The present disclosures provides a collar for positioning at least partially around a recessed light fitting and between the recessed light fitting and a structural body. The collar comprises a plurality of collar portions each of which are configured to surround a portion of the recessed light fitting.

The invention provides a lighting device (1) comprising a housing (2) including a solar-power unit and a lighting element, and a shade (3) connected to the housing (2), wherein the shade (3) is releasably connected to the housing (2) and loosely rests on an external surface of the housing (2) when connected thereto.

A line lamp is provided, which includes a power connection assembly, a light transmissive housing and one or more lamp lines. Lamp lines includes a fixed end electrically connected with the power connection assembly and a free end provided with a first connecting member, free end, and the light transmissive housing is provided with a second connecting member matched with the first connecting member. The first connecting member is a first suction member; the second connecting member is a second suction member, and the first suction member is in suction connection with the second suction member. Or, the first connecting member is a first hooking member; the second connecting member is a second hooking member, and the first hooking member is hooked with the second hooking member.

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).
