Quite good so far (first few days of use). It doesn't turn on in daylight (only for 2'' when powered). It has a microwave sensor with good sensitivity: it was placed in a balcony ceiling spot on the first floor and detects pedestrian movement below the balcony (desired for me). It also detects movement even inside the house, near the balcony door (even when it's closed). In other words, the motion detection range is indeed 3-5m.

An excellent quality LED bulb, with a very good motion sensor. Tremendous money-saving and highly durable for frequent use. The only unique detail is that the bulbs are placed vertically in spotlights, so that the photocell can monitor the area well. Hassle-free use for years.

Do not bother buying this product, it turns on and off by itself without any movement. And it does not have a sensor to detect day and night, so it stays on constantly.
