A ballast with multilateral lead wires is provided for supplying a power for fluorescent lamps. The ballast comprises a lid and a longitudinal container for containing a ballast circuit for processing an input power and generating a lamp power supply to one or more of the lamps. The circuit includes an input connector mounted on an edge of the circuit for receiving input power wires and an output connector mounted on the opposite edge of the circuit from the input connector for connecting one or more sets of output lead wires. The lid is tightly fastened over the container and has two opposite edgewise basins with access openings for the wires to the input and output connectors.

A lamp ballast is provided for attachment to a fluorescent lamp fixture. The ballast is adapted to a direct low profile mounting on a junction box of the lamp fixture by a varying degree of recessed positioning. The ballast has a built-in niche for the recessed mounting and comprises a ballast circuit on a board; a package for enclosing the circuit board save electric wires from and to the ballast circuit at multiple sides including a top surface, bottom surface and sidewalls extending between the top and bottom surfaces; and a flange extending from the sidewalls of the package at a predetermined level between the top and bottom surfaces. Thus, the flange acts as a mounting bracket of the ballast for a varied degree of recessed mounting of the ballast on the lamp fixture.

A weather resistant road light comprises a top cover and a ballast mounting surface disposed on a top surface of the top cover. The ballast mounting surface defines a ballast compartment lower surface. At least one wire aperture seat is disposed on the ballast mounting surface. A ballast is mounted to the at least one wire aperture seat. Wires from the ballast pass through the wire aperture seat. A ballast compartment cover covers the ballast compartment. The ballast compartment cover fits over the top of the ballast mounting surface disposed on the top cover. At least one securing member secures the ballast to the ballast mounting surface. A bottom tray mates with the top cover, and the bottom tray has a lens opening. A reflector assembly has a socket for receiving a bulb. The reflector assembly is mounted on the bottom tray.

A multifunction switch has a switch body; a main switch toggle rotationally mounted to the switch body for controlling completion of an electric circuit. The main switch toggle has an on position and an off position. A toggle switch button is mounted to the main switch toggle. The toggle switch button is generally planar. A secondary switch button is mounted to the toggle switch button. A secondary switch is mounted to the switch body. The secondary switch is mounted adjacent to the main switch toggle. A generally planar faceplate has a switch button opening. The switch button opening is sized to receive the toggle switch button. An offset gap is formed when the toggle switch button is moved to the main switch off position.

A garment hanger including an elongated body with at least one clamp for securely holding a garment is provided. The clamp includes front and rear clamping members pivotally connected to the elongated body, and a suspending member extending upwardly from the body for securing the hanger to a point of suspension. The clamping members have oppositely facing inner surfaces, and each surface has at least one receptacle cavity, with a protrusion therein, for receiving therein a gripping pad in an enhanced pressure-fit interlock. The gripping pad has a first side for contact with the garment and a second side for coupling with the receptacle cavity, in which at least one leg with an aperture is situated and configured for mating with the receptacle cavity and the projection situated therein. Finally, a biasing member is used to bias the clamping members towards one another to hold the garment.

An output transformer or inductor for electronic ballast which having a number of electronic components including diodes, transistors, resistors, various type of capacitors and different transformers/inductors mounted on a top surface of a PCB (printed circuit board) within a compact housing which envelops the whole ballast assembly. The PCB (printed circuit board) configured to relocate the output-transformer or inductor to an edge of the PCB (printed circuit board) away from the rest of the electronic components. The output-transformer terminal (the transformer's bobbin) has at least two of L-shaped brackets locked to the PCB's (printed circuit board) edge at its top surface. The output-transformer is designed in a cantilevered mounting so that it is able to quickly dissipate its operational heat to the ballast compact case with less interfered by other components. It also saves the PCB (printed circuit board) material cost because it uses shorter PCB.
