Abstract: System and method are provided where a plurality of luminaires, control switches, occupancy detectors, and photocells are connected to a central control module including a user interface which is used for setting up, testing, commissioning and maintaining the system; a memory card interface and associated memory card which can be used to load and save configuration data, update firmware, and log system operation. Lighting system can be set up and tested and then the configuration saved in a portable memory, such as on a memory card which can be transferred to another system where it is read to facilitate faster and easier configuring of the other system to parallel, or to be exactly like, the original system. Data stored on a portable memory can be automatically recognized to perform appropriate actions such as, for example: update configuration, or update firmware.

Abstract: A low profile linear high bay fluorescent luminaire with a downwardly facing and room side accessible ballast channel. The lighting fixture includes a housing assembly having a longitudinal axis with a first reflector located on a first side of the longitudinal axis. A second reflector is located on a second side of the longitudinal axis. The first and second reflectors are spaced apart with at least one ballast therebetween. At least one ballast is coupled to the housing assembly and extends downwardly from the housing assembly. A cover for the ballast is located below the ballast. The lighting fixture also includes a means for releasably coupling the cover to the housing assembly. The lighting fixture can be suspended from a ceiling or joist in a number of ways including mounting brackets, wire hangers, and ceiling assemblies, and can have an occupancy sensor attached thereto.

Abstract: An adjustable lighting fixture has a moveable housing. A first housing has a first opening and a second opening. A second housing is adapted to movably engage the first housing. A resilient member is connected to the second housing and adapted to be received by one of the first and second openings in the first housing. The first opening corresponds to a contracted position of the lighting fixture and the second opening corresponds to an expanded position of the lighting fixture. A lamp disposed in the lighting fixture has a longitudinal axis that is substantially perpendicular to a direction of movement of the first and second housings.
