An articulating accessory cartridge for use in theatrical and commercial lighting fixtures in which optical accessories are utilized. The cartridge includes an outer member removably insertable in the fixture and an inner member telescopically retained in the outer member. One or several optical accessories can be removably received and retained in the inner member in an axial stack, depending upon effects desired. The inner cartridge member is telescopically extended before the cartridge is mounted on the fixture. As the cartridge is inserted, the uppermost accessory engages the end of a reflector associated with a light source in the fixture. Continued insertion of the cartridge results in telescopic retraction of the inner cartridge member, depending upon the number of accessories in the stack, until the outer cartridge member is fully seated. The accessories are held against the end of the reflector for optimal efficiency of the lighting and lighting effects.

A narrow angle LED illuminated spotlight in which the light-emitting output of an LED light source is coupled with an optic element, in the form of a focusing reflector or focusing lens, and a masking element is interposed between the light source and the optic element to partially mask off the output area of the light source and significantly reduce the area of the emitted light reaching the optic element. This enables the light passed by the masking element to be concentrated into a, narrow beam (i.e., 18&#xb0; or less) using an optic element of much smaller size than otherwise, thus making the use of an LED light source module a practical source of light for narrow beam spotlights.

An adjustable track lighting fixture of a type having rotary locking lever for securing the fixture to a bus bar, where the locking lever is economically formed with an internal confinement facility of removably housing an Allen key to be retained with the fixture and used for locking the adjustments of the fixture when desired. A spring, also housed internally of the locking lever, resiliently but releasably retains the Allen key until purposefully withdrawn by a workman. The key is returned to its confinement after the workman has finished using it for the purposes intended. The key is retained in an inconspicuous manner but nevertheless visible to the workman and readily extracted for use when desired.

An electrical busway system comprising a busway uniquely configured for cutting to length in the field. Special connector devices are also disclosed, with features for engaging and immobilizing busway insulators to assure accurate initial alignment of conductors and contact elements prior to joining of connector devices with busway sections. An accessory device, specially adapted to the new busway design, includes a rotatable contact element, slideably received in its rotatable support, which progressively displaces a spring as the contact element is rotated into contact with a busbar carried by a busway insulator. Good electrical contact at both ends of the slideable contact element is assured. The accessory device also includes a positioning element which is rotatable with, but rotationally advanced with respect to, the contact elements, to accurately position, and substantially immobilize an insulator element prior to the contact elements being rotated into restricted, busbar-receiving recesses in the insulator element.
