I just bought 2 of these after reading the reviews. Will the light stay on for 3 minutes after cranking or will it last longer if you crank it more?

I am sorry. I got it as a gift for my uncle. Not sure about the actual capacity.

I've used mine for more than three minutes (after having cranked quite a bit and let it sit for two weeks). I can get four or five before I have to crank it again.It will last much longer and still produce light, BUT it will get dimmer and dimmer as the charge dies. That said, it recharges very quickly.

No matter how much I have cranked mine, I have only had it stay on 3-4 minutes. So once you have cranked sufficiently to energize, you have 3 minutes of light. I no longer crank mine more, just enough to give me the 3 minutes of light since I bought this as an emergency so I can find candles, lanterns, etc. during a power outage. I have one by my bed and one by my computer. Hope this helps.

Actually, the light is very bright. White light with 3 brightness. The crank is in case you need to charge it up due to over use or no sun. I love these little lights. We have 7 of them and use them often. The charge last a very long time. I highly recommend them.

I always leave it on charge overnight. Sometimes a little longer, and it seems to be ok. It is a very powerful light, but the instructions say to only turn it on for 30 seconds at a time, I guess it's because the drain is high, and it gets hot. So, for a quick look around, it's great. But not for continuous use.

I work ten hour shifts and have yet to have had a need to run the light for longer than 15minutes. Additionally, I will toggle with the buttons and switch from one setting to the next and so on. I even play around with the strobe light function. I have not used it for longer than 15minutes at any single given time. Just to be on the safe side I always have the second battery in my cruiser. And I charge the battery every night when I go home. Hopefully this helps!

I'm with the previous posters. Light output brightens during and after cranking. I think that is ample evidence that cranking recharges the unit.

When using battery power the backlight stays on for 2 minutes. When using AC power the light stays on continuously. (Unless you turn it off).

I would estimate the rechargeable battery lasts about 5-10 minutes. With the crank the battery does not last that long. Maybe I got a bad rechargeable battery, which suggests bad quality control. At this point it is useless when the rechargeable batteries are in the unit. Regarding the 3 AAA battery it takes, I just checked the unit and they appear to be drained, but I am unsure of the power they had when I installed them. I believe someone else documented the fact that the battery drains when in alert/standby mode. Also, the unit is quite small. It is slightly bigger (but much deeper) than a smartphone. I hope to try another rechargeable battery before I toss the thing. I would estimate the rechargeable battery lasts about 5-10 minutes. With the crank the battery does not last that long.

I just want to add onto what Energy Guy said. Yes. Flipping the switch for 3 seconds will leave the light on. The only interesting thing is, when you wait 3 seconds and flip the switch again the light comes back on even without motion. I thought I was going to have to wait till the morning till it reset itself, but, after about 5 minutes of a constant on, it reset back to motion.

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.

Not long, about 3 to 4 min. I have it in the garage. The problem is when I work in the garage, it turns off after a few min and I have to move around to turn it back up again. May need an alternative light source.

You control how long it stays on. Mine is set at about 60 sec after being tripped. It's surprisingly bright. Electric will be brighter but this is plenty to light up my yard and the patio door it covers.

Hello This is a great light and stays on for up to 12 hours after a very sunny day. It turns on at night, right at sundown. You could add a switch in series where the light sensor is and bypass the night sensor. But on a cloudy day the light will not last nearly as long of course.

It's a motion detector light, so I don't see why it should stay on for 2 hours. Mine is set for 10 minutes, or so. I've had mine for a year or two, and haven't yet replaced the bulb.

depends on how much sunlight you get, but I'd be willing bet it would last a few hours at least. Mine only comes on for a few mins at night when I come home from work. That's all I need it for. Works great, no problems with it yet. Very bright.

Don't know. Mine is connected to my cranking battery and has been left on foe 3 days and I was still able to crank motor. A friend of mine has same setup and did same after 7 days.

It stays on approx. 8 hours with a low dim light but gets brighter for approx 3min with movements. I love the lights and recommend getting them.

I found that I needed to turn the timing dial all the way and it stayed on about a minute so far. For a solar powered light , I think that's ok.If you needed something longer than I suggest having a hard wired light installed. But for me in the location I have it , that wasn't possible. It just gives me enough extra light when it comes on to help illuminate the darkness. There is an on and off switch so it would stay on longer if you desired not to rely on the sensor.
