How long does the light stay on, and some times it doesn't go out?

There is a switch on the side to select 1. On all the time 2. Off all the time and 3. Comes on when motion is detected. In the motion detected mode, the light will stay on a minute or so with no new motion detected or stay on with continuous motion detected. A great feature is that it can tell when a room light is already on and doesn't come on at all. The unit is very sensitive and if pointed toward the doorway of a room will turn on every time someone passes. To fix that we simple angle the unit away from the doorway so that it only turns on when someone is actually in the room.

If you just pass by it, and no more movement is detected, it will stay on for approximately 38 seconds, but as long as there is movement in the detection range, it stays on.

If you leave the area, it seems to shut off after 20-30 seconds. But if it detects ANY movement, even from a distance or from an angle, it will turn back on.

Hi. I think the light stays on as long as it is plugged in. I don't think it goes out when the device if fully charged, but I could be wrong. To be honest, I never paid attention. It is fairly bright, though. You wouldn't want to charge overnight in a bedroom. I usually plug mine in in the kitchen. Good luck!

A long time. I've left mine on overnight by mistake and it was still delivering some useful light.

the light has a low level light always on. When activated it stays on for appx. 45 seconds.The major item you need to address is mounting the light where the sun shines on it or at least bright light during the day for hours.

It's annoying in that it shuts off after only a few seconds unlike other motion sensor lights which can stay on for 30 secs up to a few minutes. It will stay on as long as you're moving, but if you're standing there reading a label or deciding what to wear it shuts off.

The light does stay on to let u know. But it didn't work for me. I still have mine plugged in and I still have a mouse problem. They just wait until night time now to come out and ruin stuff.

The light stays on anytime the Vac is plugged in. It does not go out when it is fully charged.

The light goes out after 60 seconds or so. It's best function is like that of a flash light: its just bright enough to help you find your way in the dark.

we don't use this in the "on" position for long periods of time to get your answer. however, we have used the light for an hour or so several times and it has worked well. we have not had any issues. i have not yet replaced the batteries since i purchased over one year ago.

there is a timer that you can set for the length of time you want the light to stay on after it is activated. Mine is hooked to a regular light switch where you can turn it off if you so desire.

It stays on until the batteries run out. Kind of an expensive decoration and alot of batteries. You might want to look at one you could plug in a wall or something

My experience has been that the light is on when it is working. I don't know if the light goes out when the battery is fully charged.

My red light eventually goes off. I have not had any issues. I typically charge the battery for a couple hours - less may work. Not sure.

Mine is on most of the time as well. It has to be pretty bright in order for it to turn off. I have it in the upstairs hallway. When the hall light is on, the night light turns off, but otherwise, it remains on.

it turns on and off by depressing the end of the light. but, the brightness is not as good as a wired lite and it really sucks up the battery juice, can use about 8 hours before it starts to dim.

Not exactly sure how long mine comes on each night but it does come on, off & on throughout the night, and I have had my first one over a year and have not changed the bulb yet.
