A lighthouse includes a mast device and a lighting device mounted on the mast device. The lighthouse further includes a main body including a box body and a top cover, the top cover is arranged on a top of the box body, the top cover and the box body define a receiving chamber, and the top cover is movable or detachable relative to the box body to open or close the receiving chamber. The lighthouse is convenient for overhaul and maintenance, and improves the maintenance efficiency.

A tool that allows a person to attach a fixture to a ceiling, and do the job on their own, quickly, safely, and without frustration. The tool includes a guiding rod that is selectively attached to the ceiling mounted electric junction box, a fixture support that is movable along the length of the guiding rod, and a lock that secures the fixture support at any of a number of desired positions along the length of the guiding rod. A first embodiment of the tool is used in pairs and includes a threaded cavity at the distal end of the guiding rod that is selectively attachable to one of the pair of holding screws extending down from the junction box. The second embodiment of the tool includes a threaded section on the outside of the distal end that is selectively attachable to a junction box crossbar that has a central threaded opening. The embodiment chosen by the installer depends on the fixture design and the preference of the installer.

A drive apparatus according to an embodiment includes a support unit, an arm, an operation target and a bias part. The support unit includes an electrically-driven first driving source. The arm is supported by the support unit at one end part of the arm, and is, by the first driving source, rotatable about a first rotational axis that is along an extending direction of another end part of the arm extending from the one end part, the arm including an electrically-driven second driving source. The operation target is attached to the another end part side of the arm, and is, by the second driving source, rotatable about a second rotational axis intersecting with the extending direction. The bias part biases the operation target in a direction toward the arm along the second rotational axis.

An adapter for changing LED light bulbs can have a threaded fitting for attachment to the pole of an existing light-bulb changer. The adapter has a body, preferably formed of a rigid material such as a rigid plastic. The body has multiple teeth to engage the spaces between the cooling fins of the LED light bulb. The light bulb can then be unscrewed from its socket and lowered using the pole and the adapter. A new light bulb can be placed on the teeth, raised, and screwed into the socket.

A string hanging device for hanging a continuous ornamental string on a physical object having a portion elevated above the upward reach of a user, is disclosed. The string hanging device includes a tubular member having an arcuately curved interior passageway configured for receiving the ornamental string. The passageway includes an entry port and an exit port. A pole member is included that has a proximal end and a distal end, and a coupler portion disposed at the distal end. A coupler is provided for removably coupling the tubular member to the coupler portion of the distal end of the pole. A hook member includes a coupler for removably coupling the hook member to the coupler portion of the distal end of the pole.

Embodiments include a lighting assembly includes an elongate gasket body formed of a resilient, optically transmissive material. The gasket body includes a light source cavity at least partially defined by a light transmission portion and an attachment channel configured to attach the gasket body to a mount. A light source is disposed in the light source cavity. Other embodiments include securement ring including a clamp portion and a lighting assembly portion. The clamp portion includes first and second segments, each being semiannular in shape and curving between first and second ends, the first end of the first segment coupled to the second end of the second segment and the second end of the first segment coupled to the first end of the second segment to collectively form an aperture. The lighting assembly portion includes a first and second segments, each being semiannular in shape and including a light source.
