Abstract
A motion sensor lighting control includes a hemispherical mounting plate having a pair of first circular apertures and a second circular aperture, a pair of lamp holders for receiving lamps therein rotatably mounted on the first circular apertures by a pair of first swivel devices, a sensor housing for receiving an infrared sensor rotatably mounted on the second circular aperture by a second swivel devices. The first swivel devices and the second swivel device are such arranged to let the lamp holders and the sensor housing to be manually rotated in universal orientations, yet limiting the rotation angle to be less than 360 degrees thus preventing the wires therein to be twisted and broken.
