I have bought and tried a number of brands with motion sensor: the least problems there have been with lamps in which the sensor is mounted directly on the glass of the bulb / lamp (manufactured by Lidl). This lamp holder here once does not fit into lamps that have a (too narrow) screen, and covers the screen too much from the sensor or not depends high enough in the room, the bulb burns permanently. It works relatively smoothly in such an (easy) versions.
