A double-ended socket system for safely and easily seating a double-ended lamp is disclosed. The system has two socket assemblies spaced a distance corresponding to the length of a double-ended lamp. Each socket assembly has a housing with a recess that houses a cylindrical socket for receiving a lamp end that rotates between a disengaged orientation and an engaged orientation. The housing has an attached electrical connector connected to a power source. The socket has another attached electrical connector that contacts the electrical connector of the housing only when the socket is rotated to the engaged orientation, thus eliminating the electrical shock hazard of conventional double-ended socket systems. The lamp may be removed only while in the disengaged orientation. A user may install a double-ended lamp into the socket system by use of only one hand. A method of use of a double-ended socket system is also disclosed.

A linear LED lamp having a body with a length between spaced first and second ends. The linear LED lamp has an elongate heat sink and a light source comprising LED emitters and a first end cap assembly at the first end of the body. The first end cap assembly has conductive power and ground pins and a support connector has conductive power and ground terminals for connecting with an external power supply and providing a grounding path for components of the lamp. The power and ground pins of the first end cap assembly are configured to engage the power and ground terminals of the support connector as an incident of the first end cap assembly moving relative to the support connector in a path that is transverse to the length of the body into an engaged position. A sleeve connector is also provided for mounting a non-power end of a linear LED lamp to a light fixture.

A lamp device with changeable lamp socket includes a light tube, a light source plate received in the light tube, and two lamp sockets locked with two ends of the light tube. The lamp socket includes a first tubular body, a first covering plate, and two conductive plugs. The lamp device further includes two adapter covers detachably locked on the lamp sockets. Each adapter cover includes a second tubular body, a second covering plate, and a conductive component. For each of the lamp sockets and the corresponding adapter cover, the conductive plugs are inserted into insertion holes of the second covering plate, and the conductive component is electrically connected to the conductive plugs, passes through an opening of the second covering plate, and exposed from the second covering plate.

A device for securing an object to a ceiling includes a threaded rod, a bracket and a spring-loaded tab. The spring-loaded tab has a tab portion with an outer surface. The tab portion is rotatable about an axis perpendicular to the threaded rod. When the device is attached to the object and the object moves into an opening in the ceiling for installation to the ceiling, the tab portion is urged from an extended position to enable the object to pass through the opening. Subsequently, the tab portion returns to its extended position such that the object can be temporarily supported by the tab within the ceiling opening. The bracket is configured so that during a removal process, a portion of the bracket urges the tab portion inward from the extended position to enable the object to be removed from the ceiling opening.
