I leave mine set to the on position always. There's a motion sensor so the light stays on & will automatically go off after about 30 seconds after closing my door. Otherwise, depending on what you're using it for you could mount on wall or door & keep in off position & then manually turn on when you need it.

I generally leave mine on overnight, but I know it doesn't need that much time. Never had one go completely dead, so don't know about that. When I observe it running really slow, I put it on the charger when done using it at that time. I find mine (and I've owned about 5 or 6 of them) usually run about a month on a charge.

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

We've left ours on for a month with no problems. It is thermostatically controlled so it seems easier to keep it on all the time than start from scratch every time we want to use it (the wax does harden when the unit is off).

I'm no electrician, but I suspect leaving it on all the time may pose a fire hazard. We leave ours on pretty much all day and turn it off at night. Remember, you want half as many watts going in to the transformer as what it's rated for (ie - 1500 max for a 3000 watt converter). The directions say to turn it off when not in use. Hope this helps.

We turn ours on and off to save energy. Turn on 15 mins prior. Works great.

yes it works up to a maximum of 12 hours when u have it timed. Other wise it stays on as long as you wish when you are not using the timer. Never a good thing to let anything run while gone just in case there is an electrical wiring fault... I always turn my things off after leaving home. I just feel safer that way.

I have left it on for extended periods but have never timed it. It is guaranteed to work for 3 years at above above normal use (9 hours a day for three years) with no change in lights or battery. It has a dimmable dial switch that allows for every level of brightness between off and ultra bright.

Saeree, I never tried leaving the light on until the battery dies. If I had to guess, based on my use and when I change the battery, I would guess six to eight hours.

If we are constantly viewing the picture it lasts about 6 hours. If it's just listening it lasts around 8 hours. We turn it off during the day when we aren't using it.

For me it lasts all day...I leave it on. At night before I go to bed, I refill it. I don't run it at its highest fan speed....that may make a difference. I've really found this to be relatively carefree. Let me know if you need anymore info!

I leave mine plugged in all the time until needed, then plug it in again. Doesn't seem to effect battery life as I've been doing this for over a year and I still get up to 6 hours of light.

I have only used mine for several short periods. Time would depend on whether you run it continuously or turn it on and off.

That's up to you. We leave ours plugged in all the time because that green light is so tiny. But if you want to unplug it just to be extra conscientious, it certainly can't hurt.

We keep it on all day and turn it off at night. It hasn't caused any problems.

Whatever time you set the switch to timer is the time it will come on every 24 hours. It will stay lit for 5 hours, then go off. Back on automatically the next day at the time you switched it. If you use good batteries, like Duracell, it will last about 100 days.
