A lighting appliance includes a housing, a lighting element disposed in the housing is capable of displaying multiple color temperatures, a control unit disposed in the housing, an electrical communication system in communication with the lighting element and the control unit, and a sensor disposed on a portion of the housing, where the sensor is in communication with the lighting element and the control unit via the electrical communication system, and when a motion signal is detected by the sensor, the control unit is configured to instruct the lighting element to illuminate in a predetermined light mode for a predetermined time.

A downlight apparatus includes a light source, a light housing and a stop unit. The driver box is used for storing a driver. The driver is connected to an external power source to generate a driving current to the light source. The driver box has a wall with an installation escape. The light housing has a light holder and a rim. The light source is stored in the light holder. The rim defines a light opening for a light of the light source to escape. The stop unit is fixed to the installation escape. The stop unit has a switch holder and a wire holder. A manual switch is placed in the switch holder and an enlarged wire head of an power wire is placed in the wire holder. An operation part of the manual switch is exposed outside the driver box. The manual switch is connected to the driver for adjusting a setting of the driver.

A folding grow light has a main body with a main body housing. A driver is installed to the main body. The folding grow light has a right folding arm and a left folding arm. The right folding arm holds at least three linear arrays of LED lights perpendicular to the right folding arm. The left folding arm holds at least three linear arrays of LED lights perpendicular to the left folding arm. A right front main joint and a right rear main joint connect the main body to the right folding arm. The right folding arm rotates from a first position that is folded in a vertical orientation to a second position that is unfolded in a horizontal orientation.

A portable light includes an elongate body having a first end, a second end opposite the first end, a longitudinal axis extending through the first and second ends, and a locking recess between the first end and the second end. The portable light further includes a movable handle that is movable between a first position and a second position along the longitudinal axis of the elongate body, the movable handle defining a grip axis that is parallel to and offset from the longitudinal axis of the elongate body. The portable light further includes an actuator positioned on the movable handle, the actuator operatively coupled to a locking pin that selectively engages the locking recess.

A yoke for a suspension system for a medical lamp comprises a rigid yoke member having a first end and a second end, a first revolving joint-component fixed to the first end, wherein the first revolving joint has a first rotation axis, and a second revolving joint-component fixed to the second end, wherein the second revolving joint has a second rotation axis. The first rotation axis is included in a plane and the second rotation axis intersects the plane or is included in the plane, and the first rotation axis and a projection, onto the plane, of the second rotation axis intersecting the plane or the second rotation axis included in the plane enclose an angle (α) of more than 0 degrees and less than 90 degrees.

A warning system for a work vehicle includes an arm mount attached to a side portion of the work vehicle above a head of a person standing on a ground surface adjacent to the side portion of the work vehicle, and an arm attached to the arm mount. The arm is movable from an arm transport position, where the arm is oriented inside a path of the work vehicle, to an arm operating position, where the arm extends laterally outward from the side portion of the work vehicle. A warning light is mounted on the arm and is visible to traffic approaching the work vehicle from a rear end of the work vehicle, and a work light on the arm shines downward on the operator to illuminate the person the oncoming traffic and to facilitate operation of controls.
