A light system for an aquarium includes an aquarium tank and a lid covering the open top of the tank. The lid is pivotably attached to the tank and is pivotable between a covered position and uncovered position. A light source is secured to an interior portion of the lid and moves with the lid between the covered position and uncovered position. The light source emits a. light beam. An alignment arrangement is provided for the light source and is constructed and arranged to ensure the light beam projects into the tank interior volume regardless of the position of the lid and light source.

Example embodiments described herein involve a system for testing a light-emitting module. The light-emitting module may include a mounting platform configured to hold a light-emitting module for a camera. The mounting platform may also be configured to rotate. The system may further include a housing holding a plurality of photodiodes arranged in an array over at least a 90 degree arc of a hemisphere. The system may also include a controller configured to control the photodiodes and the rotation of the mounting platform.

An improved decorative lighting system constructed having a support framework assembly for mounting decorative lights in connection with a window frame. The support framework assembly comprises a plurality of tubular track members, each formed having a slotted chamber section extending the length of the track member with a squared outer edge formed along either side at the base of the chamber to provide a substantially flat planar surface along the base of the track member. A plurality of articulating end clips are formed to engage each track member and interconnect with another to join the track members in a substantially rectangular configuration adjustable to conform to the shape of the window frame. A plurality of specially configured light mounting clips are formed to press-fit and slide along the flat perimeter surface of the track members and hold the decorative lights in selected positions along the track members. Ring members included upon selected ones of the articulating end clips are used and positioned in upper corners of the framework assembly to engage conventional hooks or tabs secured to the window frame and facilitate the mounting of the framework assembly and its removal and storage when desired. The articulating end clips further allow the complete support framework assembly to fold and store more easily.

An improved dimming apparatus is disclosed. Major economies are achieved by the ability to distribute groups of dimmers in proximity to the lamp loads that they control. Variations in the location and distance between the apparatus and lamp loads, as well as in the differing connector types installed on such loads, are addressed by terminating the six power stages contained in a common enclosure in a six-circuit multi-pole connector, such that a variety of prior art “break-out” adaptors between said multi-pole connector and individual circuit connectors can be selected among. The power input to the enclosure can be made re-configurable.
