Other bulbs when left for a while do not switch on again when someone enters the hall. I have tried 3 different PIR light bulbs and this one has a unique fearture. The sensing distance is about 3-5 meters based on the placement of the bulb.Overall, this item scores a five in most of the departments if not all and hence deserves 5 stars. You need to move your arm or body around for it to detect some movement. Merely, sitting in one place and shaking your head won't trigger them. Also, they require the movement to be of a displacement type. They switch off after ~1m of detecting no movement. For a 6W they are comparable to an incandescent 50W bulb and easily light up a 5x5m room. Just let them be and they start functioning as expected. I didn't really understand why therefore thinking both the bulbs I received were faulty. The top dome feels like glass and is thick enough to assure that it wont just break off.Function:When you switch on the bulb for the first time, it comes on and stays for quite sometime. The silver part that is used to dissipate heat is solid and heavy and appears metallic. Most of the bulb is of plastic construction but very good quality. They do not feel cheap like some other ones. There was no damage on the packaging.Build quality:The build quality is what compelled me to write the review. However, the boxes itself are strong cardboard and could probably take all the hits while being shipped. It was just one of those thick plastics wrapped around the bulb's boxes. The packaging was a bit nifty for a product that's being shipped overseas. Nevertheless, expected date was 9th December so arrived well ahead of time. So its most probably being shipped either from China or the USA, where the company says it is based. So here goes.Delivery and packaging:I placed the order on the 6th of November and received the product on the 21st. I must admit the quality of these bulbs had a hand in me writing this review.
