If this light was to stay on, how many hours would it last?

We took two of the lights with us to a night outing in Golden Gate Park and with fresh batteries the lights last a full five hours (a little before midnight, one light outlasted the other by about fifteen minutes). The light is not your conventional soft white light but a very bright and crisp light. It is the same light you see in oncoming headlights of newer cars. Great to play cards by, eat dinner or to sit around at night at a patio table. I keep two lamps in a living room book cabinet and they light the entire living room area if on by themselves. I also keep one on auto-light in the bathroom on a high shelf so that when you walk into the bathroom late at night the light goes on offering plenty of light and stays on thirty-seconds after you walk out. If you've a room with few electrical outlets or an area where electricity isn't available, these lamps are excellent. You can get the batteries (Size D) in bulk package from Radio Shack at very reasonable cost.

use pro cell batteries, I have had this lamp, with the same batteries, all summer, I use it to read while camping, as a night light, and leave it on auto to light when we go in and out of camper. Pro cell batteries will last SO MUCH LONGER

one AAA battery, replace the handle and slide the ridged button up to illuminate the long-lasting LED light. (LED light lasts for 8 continuous hours, or 100,000 hours if used only intermittently.)

No,the light will stay on for about 20 minutes then shut off after there is no motion.

I don't see why not. It's just turning a light on and off. It has a timer inside that you can set how long you want it to remain on.

I can't tell you exactly since I usually keep it on for no more than 4 hours at a time, then I will recharge it.I've had it on for 4 hours straight at the high setting without it dimming at all. I suspect I could get at least 6 hours at the lowest setting.

Very rough estimate, probably around 10 hours till it's completely dark... that said, it depends on which setting it's at (there are 3 brightness settings), and it doesn't just go dead, it gradually gets dimmer with time. I have not had it actually turn off even after probably more than 6 hours of use over a long period (i lost the charger), but it definitely got dim. I'd say you have a good 4-5 hours that it's "strong." For what it's worth, it can get power/charge from a USB port on your computer in addition to the wall outlet.

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.

I don't know as I only use it for 1.5 hours at a time and I never really checked but I am sure you could get 4 hours or so all I can say is that this light is super bright and I sell led lighting for a living.Solid in the hand and overall impressed with the quality...

Not long at all. I had to stop using mine. When you put batteries in you get about 8-9 good hours, then light begins to dim. It is worthless!!

More than 2 hours actually. I left mine unplugged running at max brightness overnight to see how long the battery will last. I was up for more than 5 hours before falling asleep and it was still running. Light at max wasn't as bright compared to when it was plugged in though. There's most likely a circuit preventing the battery from over discharging as it turns on then off for some time still before I plugged it back in.

It all depends on what you're running on it. If I'm using a sixty Watt bulb it's good for 11 1/2 hours. That's what I use it for in the summer at festivals.

I don't know. It was in my house for an hour and then back in the box. I think it can stay on. The timer may just be an option...

This lamp is supposed to last up to 10,000 hours, so you would replace the lamp not the bulb.

I haven't tested it (Thankfully) but I think I read in the packaging that it would last up to 48 hours. They are really fine LED lights so I could imagine it would last several hours for sure.

I do not know how long it would last, however we had a power outage of 1 hour and 15 min a few weeks ago and was during the day. The flashlight comes on automatable but our hallway is dark and the night light stays on. I pushed the button to turn off the flashlight and left the night light on. After one hour and the 15 minute outage the nightlight was just as bright as when it first blacked out. In one hour there should be plenty of time to get some lights going (flashlights etc.). With the lamps being LED I am convinced there will be plenty of time on the battery. Hope that helped, I'm sold on it.

Usually this light has a dedicated feed which keeps the battery fully charged. If you wire it or feed it through a switch, it would wise to make sure that nobody turns the switch off. Remember that this light is designed to work when there is a power failure and will usually work only for four to six hours after a power loss.

About 2- 2.5 hours. Make sure you stick the battery pack in a ziplock bag if you plan to use it in the rain as it's poorly sealed. Other than that this light is awesome!
