  • Publication number: 20110269353
    Abstract: A lamp system used in a light string system comprises a light assembly and a socket assembly. The light assembly comprises a light source, a base in communication with the light source, and a bypass activating system. The socket assembly comprises a socket adapted to receive the light assembly and a bypass mechanism having a first position and a second position. The bypass mechanism is in the first position when the light assembly is not seated in the socket assembly. When the bypass mechanism in the first position, current flows across the bypass mechanism. When the light assembly is inserted into the socket assembly, the bypass activating system of the light assembly moves the bypass mechanism into the second position, and current flows through the light source instead of the bypass mechanism.

  • Publication number: 20090188845
    Abstract: A cleaning system container includes a base, a side wall, a viewing portion in communication with the side wall, and a cleaning system. The viewing portion is a porthole of the side wall, which provides a window-like mechanism permitting one to see into the cleaning system container through the side wall. The cleaning system container defines a hollow cavity and is capable of holding a fluid, which can receive the cleaning system. The cleaning system container can include a filter assembly and/or a skimmer assembly. By positioning the portholes in desired locations, the amount of waste captured by the filter assembly can be ascertained without the need of opening the cleaning system container, prompting swimming pool owners to change the filter cartridges more frequently, which can improve its overall performance.
