How long does it stay on?

It stays on forever, or until you turn it off. Some other products foolishly click or go silent for one second every 3 minutes when they reach the end of their built in digital recording, and then the white noise resumes again. The Marsona does not have this problem. Its noise is continuous.

It is at least 24 hours. Actually, I left it on one night and it think it said 37 hours and counting when I got back to it.

U can leave it on all night. I have 2 teenagers who leave them on constantly. There is a timer for upto 8hrs if u want that option. So far these have held up well and I recommend them.

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.

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.

That depends on the setting. I've never had it on long enough to go out. I usually use it on the brightest setting and have had it last >90 min without dimming. I believe the manufacturer states that it can last 2 hours on that setting. Lower settings will obviously last longer.

I don't know! Sometimes I leave mine on all night and other nights turn it on or off during the night. I absolutely love it though. So glad I got it. I ended up getting two. Do you want it on more than 10 hours?

I am not good at judging lengths of time, however it stays on quite a while maybe 15 - 20 seconds. If it goes off as soon asyou get in front of it will come of it the lamp comes back on. I LOVE mine.

I found it stays on for 30 seconds, then turn off regardless if you are in front of the sensor moving around. It will then to take about a full second before it will come on again if you move around the sensor

I have had mine for a couple of years. It does stay on for more than 4 hours. Unless they improved the battery draumatically you will not get 6 - 8 hours.

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.

20-30 minutes. Same amount of time you keep the gel on. The directions suggest not leaving it on for more than thirty minutes.

I don't seem to have this problem. I've not timed it, but I'm pretty sure mine stays on for well over a minute. Perhaps playing with the settings?

it stays on for about 15-20 minutes, and the batteries seem to hold up for quite some time. My granddaughter loves it!

I've had mine on for about an hour at it's longest. I don't leave it on without something in the cup, and I don't leave it unattended when it's on. The switch is very convenient for turning it off and on as needed. It also heats up very quickly. I've been using it for about one month, so I can't verify durability. It seems to work well, except it's not quite hot enough.

Mine have been in since I bought it, so over a month so far. They say two months, longer if you turn off when not in use. Mine has been on 24/7.

Depends how long you leave it on. If you leave it on all night, probably a couple of weeks. It gets dimmer as the batteries die.
