A retrofit switch apparatus is designed for attaching to a mechanical switch. The mechanical switch has a manual switch for performing an operation of a connected target device. The retrofit switch apparatus includes an assembly box, a wireless module, a switch unit, and a control unit. The assembly box covers the mechanical switch. The wireless module is used for receiving an external command. The switch unit has a driving structure. The driving structure is disposed in the assembly box for engaging with the mechanical switch for moving the mechanical switch to perform the operation according to the external command. The control unit has an operating unit and a trigger unit connected to the operating unit. A portion of the operating unit is exposed outside a surface of the assembly box for a user to operate to directly trigger the mechanical switch.

A wall grazer apparatus is provided. The wall grazer apparatus has a heat sink platform, a light source, a lens, a driver and a main housing. The heat sink platform has a main portion and a tilt portion. The light source is mounted on the tilt portion. The lens is disposed above the light source to convert an original light emitted from the light source to an output light. The driver converts an external power to a driving current. The driving current is supplied to the light source. The main housing disposes the heat sink platform, the light source, the lens and the driver. When the main housing is fixed to a first surface, the output light is projected on a second surface for forming a visual effect.

A low-profile recessed light fixture has a housing with a low height and forming a light engine enclosure with an aperture. A light engine assembly within the light engine enclosure as a heat sink assembly and a light emitting element. The heat sink assembly has first and second heat sinks, and the light emitting element is mounted to the first heat. The first heat sink is operable to tilt relative to the second heat sink about a tilt a tilt range. The light engine assembly is operable to translate between an operation position and an offset service position. In the operation position at a zero tilt an optical axis of the light emitting element is substantially parallel to a vertical axis passes through a center of the aperture. The light engine assembly being operable to rotate relative to the housing through a rotation range of at least 360 degrees.
