These were exactly what I was looking for, I needed a light for my daughters wardrobe and was considering the push in lights as I didn't want one that ran off electricity as my daughters have a habit of turning lights on and off or just leaving them on,and with it just being for their wardrobe for short periods of time and this item is perfect for that. It arrived in amazing time. The motion sensor works perfectly on it, so as soon as I open the doors it comes on. It provides a very good light, and it stays on for 2-3 mins. It obviously has a sticky back which was easy to remove and it is easy to stick on to the surface and it hasn't detached since putting it up. It does require 4 batteries and I recommend getting rechargeable ones. It also has a day and night setting although I'm not entirely sure how it affects the light as it didn't come with instructions so I'm none the wiser to that, it also has what looks like the timer for the lights once activated I presume but again with no instructions it is guess work. They were perfect for what I needed and will be considering on getting more for my stairway.
