These are the ones that've just arrived today for me. They are brilliant! Although they have sticky things you can use, they are magnetic, ideal for in-cabinet use and whipping out to charge them. They have a few settings but the most useful looks to be the one where, day or night once it detects you, it switches on and will stay on for around 15 seconds when it switches itself off, assuming no further detection. And the light, unlike some cheap LED things does seem to usefully flood your cabinet. Brilliant! So obviously once you close the cabinet, it'll switch off after the given 15 seconds.
How long do they last before they need charging? That I can't tell and, obviously I didn't charge them before putting them in because at heart, I'm a kid with a new toy and couldn't wait!
