How long does it stay on when used?

As long as the filter, which is short, touches the water. Maybe 6-8 hours. My biggest concern is that it doesn't screw onto the bottle even though it's supposed to. It doesn't sit upright on the bottle and in danger of tipping over.

when nit's new a long time, till filter does not touch water, then after a few times it doesn't always work, and then not a long time if it does.

To tell you the truth, I never finished it. I use it in the office. It runs for about 8hrs or less then I take it apart when I leave. I think it depends on how big of a water bottle you use. It hasn't broken down on me yet. So it's been good so far.

It stays on for as long as you have it plugged into an outlet. I even plugged it into a timer and had it go on and stay hot for several hours until the timer shut it off.

One application will stay on for 1-3 days. However the longer it is on it can cause irritation. Once taken off it will not stick to use again.

Yes, There are 3 settings: on, off, and timer. On will keep it on until you turn it off. Timer leaves it on for 5 hours and will turn it on for another 5 hours the next day.

Though I manually turn mine off to make the battery last as long as possible; the manual indicates it turns itself off after 10-15 minutes of inactivity.I consider that to be both good and bad. It's good if you're forgetful - it's bad if you want to closely monitor something longer than some preset time limit.

I haven't timed it, but I would estimate that it stays on for about 15 seconds. It lasts just long enough for me to open the combination padlock on my shed. I don't think the time it stays on is adjustable.

I looked up the manual and if you set to 0, it is ON all the time. If it is set to A, on at dusk and off at dawn. If it is set to any number, it will stay on for that many hours after dusk. You scroll through these settings using the up/down arrows.

open the velcro on the underside and up toward the neck is a switch to select how long it stays on for. it is probably still on "try me". you can choose 15, 30, or 45 minutes....or "off"....also important to know!

No, it stays on until you turn it off. This is electric, not battery operated.

It will turn off after about 5 minutes of not being used. It also doesn't drain a ton of Battery while being on because it's just the light of the device that's on.

Several hours. Check the item description. and google the item title for blog discussions for more details. I think it also matters on what you hook up to it, but I'm not certain. It's also ok to keep it plugged in while it is in use.

The light stays on as long as it detects movement and it is dark. Once movement is no longer detected, it takes about 20 seconds or so to shut off.

It stays on. We use it here at the Senior Center and it stays on from about 9:00 a.m. till lunch at 12:00.

It remains strong for about 20 to 25 minutes of on and off use. I don't have a lot to take care of so I am turning it on and off often.

It stays on unless you turn the button off. Hope that answers your question.

It lasts a good 6 hours at least. Source: I accidentally left it on overnight

the light can be set to stay on for up to 15 minutes when activated by motion. I have had mine over a year and have not had to change the bulb yet. I expect it to last several years.
