Image of this flashlight says 79h? Does it will run for 79 hours?

I have no idea how long it will last. I will tell you this though, I once used my flashlight to plug some cables into a computer under my desk that had poor lighting on a Friday. I completely forgot about it over the weekend and walked into my office that Sunday and noticed my flashlight was still on. It still seemed as bright as ever. I still haven't changed the batteries in over a year since that incidenet.

Don't know, never tried to run it that long. It runs much much longer on it's batteries than conventional flashlights.

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 can't answer that question but when I bought mine it was listed as flashlight only and when it arrived it did not work so I returned it for a refund.

I am sorry but I truly have no idea. I know it is the brightest flashlight I have ever owned and I do let everyone know it is worth the money. sorry I could not help with this question.

I have no way of testing the actual lumens but it is the second brightest light I have next to my nitecore mh25. It is plenty bright and it will run for about 2 hours on high.

I'm sorry, but I can't answer that question, since I never timed it. I can say that this is a super bright flashlight, with a beam of great range and width. I mainly use it to keep tabs on what my dog is doing in my back yard, and it lights up a great swath of the yard. I have been more than satisfied with the duration, and recharge the batteries about once a week, but I cannot quantify the battery light in terms of "How long does it last @ 4000Lm?". I have three sets of batteries, so I can pop a fresh set into the flashlight if its brightness begins to wane. I can say that it does not seem to have a sharp cutoff - the brightness just begins to slowly diminish.

The flashlight is super bright, for some applications I actually have to dim it to see labels. I do home inspections and it makes it through at least 2 inspections of approximately 3 hours each. I use rechargeable Eagtac 3.7v 18650 battery Li-ion 3400 mAh. I really like this light. Hope this helps.

Lately I've been a bit disappointed with the flashlights run time. I usually keep mine on the base but it's been dying withing 20 minutes or so, with noticeable kick down after maybe 5 minutes. This is leading me to believe it's probably better to charge it then take it off then only charge it when it's discharged. That's basically what I did with the first one I had and the battery had longer full run time over a much greater period of time.

I'd say it's good for about a month. Never tested it out as I use it before it gets to that point.. but I do know that it's rather easy to accidentally turn the flashlight on. Not a problem if you can see it, but sometimes if it's in a bag/pocket... you won't know til you try to charge and it's dead.

Wish i could answer that question; but the flashlight was stolen from my tool pouch in about a week. It is a pretty wicked light!

Not sure. But I will say this. After having this flashlight a few years, I will NEVER EVER EVER again purchase anything like this ever again. The bulbs went out too too too often. Constant replacement of the bulb exceeded the initial cost of the flashlight. This was by far THE WORST investment that I have made in a long time. A waste of money. I now use a rechargeable battery operated flashlight. So when the battery dies, all I do is recharge it and go. This flashlight is not worth the money. Sorry.

Dear Customer, The run time is: 1 hour at High Mode (930 lumens), 2 hours 10 minutes at Medium Mode (530 lumens), 10 hours 30 minutes at Low Mode (100 lumens). I hope I answered your question. Thank you,

From what I can tell so far, when running continuous on high, the battery only last around an hour. But that probably isnt real accurate. My uses are on and off a lot. I dont usually run it for more than a few minutes at a time. I do know that this light does get hot to the touch when its been on for an extended period of time.

but I just noticed that the description says 21 million volts, the flashlight I purchase was described as 12 million volts and it was exactly 12 million volts as represented so I'm believing that this one you're talking about would be 21 million volts you could send this question to the actual seller to see if you could give you more of a detailed answer than I can provide, have a good one man take care.

Well, this flashlight doesn't have a bulb, but an LED. The LED is soldered to a circuit board. It is my understanding that these Cree LEDs are rated to last many 1,000s of hours if not 10s of 1,000s.

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.

They do not have any specification on that. This is simply a cheap, made in china, rechargeable flashlight. No frills or fancy claims about the technical whizbangery.
