A lighting system includes an LED downlight mountable to a ceiling, a driver, and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The driver has an input with a first voltage and an output with a second voltage, the second voltage being lower than the first and being provided through a wire system extending from the LED driver. The IDC connects the downlight to the wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding IDC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.

A lighting unit, configured and adapted for illuminating subjects for photography and filming, has a connecting element that comprises, on the one hand, plug-in locations configured and adapted to receive at least two light sources, and, on the other hand, contacts configured and adapted to be connected to a generator, the contacts being electrically connected to the plug-in locations. At least two light sources are inserted into the plug-in locations. A substantially transparent protective cover is connected to the connecting element and at least partially encloses each of the light sources connected to the connecting element. One light source is designed as an HMI (Hydrargyrum Medium-Arc Iodide) light and the at least one other light source is designed as a flash tube. A lighting device including a lighting unit, and a reflector assembly with a lighting device, are also disclosed.

A COB LED lighting lamp cooled by a liquid agent, in particular water, used for year-round illumination of the LED light of this lamp in a greenhouse of plants and includes a load-bearing and lighting component, having a cooling plate with three threaded mounting openings arranged transversely, the inner surface of which with channels for the cooling liquid flowing through it is permanently and tightly connected with a cover equipped with neodymium magnets magnetically connected to contacting neodymium magnets of holders fixing COB LED modules equipped with COB LED diodes and lenses, and a cooling subassembly situated above it, including a cooling fan and a water radiator placed thereon and detachably connected thereto. Both components being connected to each other by two connecting pipe sets, such that the upper connector of the pipe set is screwed into the threaded opening of the water chamber of this water radiator.

Strip lighting systems that include a series of LEDs and which comply with AC driving power.

A mounting plate assembly has a mounting plate for mounting a light fixture in holes of different diameters and wherein a guide rail assembly is secured to a rear face of the mounting plate on opposed sides of an aperture. Each guide rail assembly has a novel displaceable spring clamp structure having to a displaceable base coupled for sliding displacement along a guide rail assembly. Spring biasing elements are provided between the displaceable base and the guide rail assembly to urge a bottom face of the displaceable base against a flat top surface of a mounting base to which the guide rails are secured. A retention formation is provided in the bottom surface of the displaceable base for retention coupling with a selected one of space-apart engageable retainers immovably secured to the flat top surface of the mounting base and aligned with the retention formation to arrest the displaceable base at a desired location to position the spring clamp structures at a desired location with respect to the size of a hole formed in the sheet material and to which a light fixture is to be secured.

The present disclosure is directed to a stern light for illuminating a watercraft without visually impairing a passenger of the watercraft. The stern light includes a flexible pole with a hollow interior for housing wires. The wires are connected to a watercraft at one end of the pole and to a light source at another end of the pole. The light source, which may be an LED light source, is covered by a globe that at least partially refracts light. When powered, the stern light produces light capable of providing visibility of the watercraft for at least two nautical miles while also avoiding the visual impairment of watercraft passengers. Pole flexibility allows operation of the stern light during watercraft motion and in areas with potential obstructions, such as low-hanging branches.

A furniture item includes a main body with an electrical device installed thereon. A power line electrically connects the electrical device to an external power source and is concealed in a power line channel formed in one or more of the walls of the main body. A switch may be connected to the main body and electrically connected to the electrical device, for controlling the electrical device. A main body door moveable from a first position to a second position may trigger the switch to enable and disable electrical connection between the external power source and the electrical device.

A multi-conductor bus with radially arranged conductor wires on which addressable bead devices that may incorporate light-emitting diodes (LEDs) or other surface mount devices (SMDs) can be easily mounted. The radial bus is designed to provide an improved range of flexibility and motion while allowing for easy addition of bead devices along its length that utilize self-addressing bus protocols such as cascading device protocols. The design of the flexible, interruptible radial bus facilitates the use of pass-through and interrupted paths along the bus that simplifies the installation of addressable devices along the bus such as the bus-mounted bead devices disclosed herein.
