how long (Hours) will the three side LED light stays on during a power outage.

I did a test on mine which is about 18 months old. On a full charge, 3 lights illuminated on the side, it lasted 27.5 hours. It was still illuminated but about 1/2 the brightness of a full charge. You can easily get 24 hours of useful light out of this.

I have only put these to the test once...but I used it for a good five hours before my lights came on during an outage. When the power went out, they came on, and very bright. I could see my way around my house. I used one to read by, another to cook by. I have purchased them for all my family...good to have!

I've been testing mine since this question came in, 4 hours continuous use of the 3 LEDs since I turned it on (i.e. unplugged it from power) earlier today to do a test. It's still "on" and still quite bright after that time. I rely on these (I have 2 of them in the house) to come on automatically in an outage, and help me find my way to my stash of brighter flashlights and other emergency supplies. They do cast plenty of light for that and other basic purposes. If you REALLY don't want to be in the dark though, consider having additional sources of battery-powered light in your emergency kit. As we've all learned recently, it may be days rather than hours that you'll want some light.

it lasts approx. 5 hours. that's why i bought more of them to put around. when the power goes out at night it helps to find your way around the house right away, then i just keep a few in where i need them so i can swap out if i still need light longer. the 3 leds in the front are very bright to light stairs & hallways, i like this model the best of the ones that i have. started looking into a back up power supply and/or a solar generator but didn't buy any yet but it would be good to recharge power for an extended outage.

It is a non user serviceable sealed assembly. The LEDs should last 10's of thousands of hours. However if one goes out then 3 will because there are 4 x parallel series of 3 LEDs. If one series of LEDs goes out the odds are the problem is the driver circuit not the LED itself, so you would either accept that it became a ~ 15W light that's a little dimmer or buy a new one.

If you want to leave the other two lights on all the time this will work fine. Obviously if you turnthe switch off the unit will not work. If you turn the switch off and back on again later the motionsensor lamp will turn on and stay on for about 10 minutes then turn off and turn on when it sensesmotion

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

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.

Below is what the tech specs say about loss of power. There is no replaceable battery that I see. I suspect it the local time is saved via a capacitor type back up and the other settings are stored permananetly any time you set them. I have only reset mine once and that was because I wanted the light to come on later because of holiday deco's on the porch. Power outage: The screen is blank. Only the time must be set if the outage lasts more than 4 hours; all other settings and programs are permanently saved.

If it's in a shadow it will probably be on all day. It's led so it will still last a really long time even if it's running all day.

They would have to have some type of ballast system to power the light. I would just replace the entire unit. There cheap. Mine seem to last about 3 years but i only run it on the weekends. I want to update to an LED in the future. Good Luck.

You cannot! When the unit fails, you toss it. These are disposable like printers. It does not pay to fix them. The lamp is all sealed, nothing to service. The reasoning behind this is that LED's last a few thousand hours and should give you about 3-5 years of service with normal use.

Theoretically, leds should last for years regardless of operation hours. If they fail from defect, it is usually right away. That said, voltage spike or damp will shorten average lifespan.

Well, after a month but not using it every night...it's still on the original set. Since the lights are LEDs, it should go for a very long time.

Dear Customer, If this LED lamp is fully charged, it will last 7-10 hours. Please be noted.

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.

The 60 LED on this Solar Motion light can be set to stay on from 20 seconds to 4 minutes at a time. The light will last for 4 to 8 hours on one charge depending on the duration setting and the number of iterations triggered by the motion sensor. The light will illuminate an area like a 40 to 50 watt light bulb, so enough to see where you are going, not enough to read by.

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.

Should last for months. LED use little power. Mine has been up 2 months I think.
