How many hours does the light last?
1533078
I have only used it a few times outside and in the attic for a total of 2 hours. Still working great. I have not had to change batteries. I bought two of these including one for my father. We both like the adjustable beam. Interestingly, when tightly focused the light projects a rectangular shape. We are pleased with the item and think it is priced fairly. Exceeds our expectations. Hope this helps.

This depends on how dim you can accept before you declare that the time period is over. The longer it runs the dimmer it gets, running many hours but most of those hours it is not very bright.For example after two hours it will be less than half as bright as it was when first turned on. After 3 hours it might be around 20% of initial brightness and so on. It also depends on which type of batteries you use. High self discharge NiMH will run it longer than alkaline or low self discharge NiMH but with the high self discharge cells you must charge them not very long before you plan to use the light if you want to get full rated capacity out of them.

The battery will provide 1400 milli ampere hours over it's lifetime. That's 1.4 ampere hours or 1.4 amps for 1 hour. If your light uses 10 milli amperes, the battery should last for 140 hours.

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 have never tried it, but I can tell you it lasts a LOOONG time!! Its the handiest light I ever bought!! From using it ,I estimate about 3-5 hrs continuous.

It lasts 4-5 hrs on medium power, its a very bright lite, I like it. If you babysit the power button it could go longer.

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!

Seems to be about 3-4 hrs. It depends on how bright you run the screen and what you are doing.

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.)

I have been using this product for about two weeks now. While the battery is not great or 6.5 hours, it is most certainly close to 3:30 hours. IF you keep brightness to a min it will last even longer. Hope this helps.

Not sure if it lasts 24 hours, since I use it for an hour at a time, but I usually only have to charge it every other week or so. It does gradually dim, but in my experience it stays bright for most of the two weeks, then gradually dims just at the very end until it dies. Incredibly reliable light.

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.

I would say AT LEAST 8 hours, but probably substantially longer. I accidentally left them on the whole night and in the morning they were still going (this was also after weeks of use-where they were on several hours a night). I'm only saying 8 to be on the safe side, and to ensure that they remain bright enough, etc.

I would say around an hour. My problem with the light was flooding. I know of at least 6 of these lights that flooded. It lasted 5 or 6 dives...

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.

Assuming a usage of 4hrs/day, it gives 12500 days of use ie roughly 34.25 years. Assuming a usage of 10hrs /day, it gives 5000 days of use ie roughly 13.69 yearsI am not sure if there is documentation explaining about replacing the light, If I am going to be around that long, I would get a new lamp.

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.

the lights last a good 8-10 hours if not longer after a full day in the FL sun!
