how long will the batteries last if the device turns the light switch on and off once a day?

I have not had to replace batteries more than once a year - and mine turns on and off once a day all year.

Have had a set of batteries (alkaline) in, for over a year, and it still functions fine. However, I would suggest changing them every year, or so. Beats coming home to a dark porch/front door.

I had one set of batteries last about 3 months.. the second one was still going at around 5 months when I took it off the wall.

Ours has been in service for the last year and we decided to change the batteries this March when we turned the clocks ahead for daylight savings time, although there was nothing wrong with the batteries in the device. We do use a better brand of battery in the time though.

That's a good question, however I've only had it for around 2 months, so I don't know an answer yet.

Mine can last all night long and into dawn if I have them only on motion detector mode. If it is on continuously and is FULLY CHARGED I have had the light stay on for about 6 hours.

I don't think so. It uses LED lights, which should last 35,000-50,000 hours, so you will never have to change them.

I haven't timed them. I use it for about 10 or 15 minutes per day, and I have to change the batteries on average once a month.

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.

One person wrote that their batteries lasted for 24 days having the candle operating 24/7 before having to replace them. On a timer of course,you will probably get two/three months of battery use.

I have been using this mouse with the lights on setting for a while and it seems that I use about 2 batteries every week to week and a half, but I have not used the mouse for very long in the lights off setting so I'm sure that they will last longer if you have the lights off.

Almost 6 mths to the day - the little red light will steadily glow when the batteries start to wear down. We installed all of the window and door sensors that came with our package on the same day. All, without exception, died within 3 days of one another.

As far as I know, no it doesn't. Simple on/off switch turns on light. I suppose you could keep it "on" all the time and let it run out of juice, which would be replenished the next day when the sun is out?

Most batteries last 4-5 days depending on how many hours you have them on each day.

Depends on how often it is activated. It runs on 4 C batteries. I've had two outdoor ones in for over a year and have not replaced the batteries yet. The light will be dimmer as the battery power fades. It shouldn't just abruptly stop. Hope this helps.

May be, but it depends how you use it. If you turn on/off many times usually it lasts less, if you keep it on more constantly it may last more hours.

Yes, that's correct. I think the amount of time that it stays off is programmable. This is quite a nice switch although I haven't figured out how to "train" it to only come on when it's dark. I haven't really taken the time to work with it. The support folks are very helpful and friendly.

The batteries are already in the light. Just place the light where it will get direct sunlight for 3 - 4 days, after which you can turn on the light in the proper mode that suits you. These lights need at least 10 hrs of sunlight a day.

It depends on how often you will use it . If used a lot i don't think the battery will last for several days.

I have used this light for diving and usually get closer to 1 hour of use per set of batteries. I usually change them better dives. When they Hey low the light does not dim. It will just shut off.

There is a photo sensor which you can set to turn on and off the lights. It also can be set by number of hours by digital selection. I usually set my for 4 hours when I use it.
