What's your experience as far as the 820lumens lasting 3hrs(and is that only w/ a certain type of battery)?

Unfortunately for me the battery does not last three hours at full brightness. As with any LED light once there isn't enough better charge rather than getting dimmer the LED will start to flicker on and off. So I guess depending on the quality of the battery you get varying lengths of full usable boringness. I usually get about 45 min of continuous full brightness before it flickers, although capers batteries i have used don't last as long.

I am not sure if it is in fact 820 lumens, however the light it's SUPER bright! You can easily blind someone with it LITERALLY... I am a current law enforcement officer and I use the light a lot on my graveyard shifts, the battery last about 2 weeks with multiple uses. The flash light does not use regular batteries however it comes with 2 rechargeable batteries and it uses only one battery at a time... Overall I am really happy with this flashlight and I highly recommend it.

I've never had mine last 3 hrs on the 820 lumen output. An hour to an hour and a half would be more accurate based off my experience. That's with the surefire cr123s you can find at lowes and some cheap 18650s.

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.

I recently purchased the Tenergy charger with the 2600mAh Li-ion dual batteries and when I brought the Klarus XT11 I get about 8hrs of use with no problems. I'd say the best flashlight I've owned to date.

I have used 2 different batteries. Klarus 2200mah and an eagletac 3100mah. Both have about the same results and last 2 1/2 to 3 hours on the highest setting. The klarus 2200mah will not be as bright as the eagletac but will give you about 3 hours, and the eagletac will be slightly brighter but gives you about 2 1/2 hours. It's not a problem for me since I carry extra batteries. Is it worth it???? Definitely!!! Best flashlight I have ever owned...I have 2 of them. Keep in mind that these numbers are on the highest setting... you can still drop to medium and low after a few hours.

I have never had to use the flashlight for more than a few minutes at a time, but I do use it frequently each night. I use Orbotronic 3400 mah batteries that are fantastic. I change the battery once every month or so.

It's been my experience that most high end flashlights (with power management circuitry) fail to live up to the manufacturer's claims. They're general guidelines at best. Granted, I've never actually put the flashlights up against a clock, but I think the Klarus is as good as any. Honestly, I think the brand of battery is a more significant factor. I typically use Duracell, Panasonic, and Surefire. I've had noticeably poor performance from cheap batteries.

I cannot really confirm the 3 hours number: I can tell you I have only used 1 set of batteries in 3 months of fairly regular use. I rarely have the light on constantly for over a minute at a time though. I bought my batteries online at Home Depot-surprisingly good price and name brand. Am happy with the light so far--extremely bright-good range.

It definitely lasted more than 2 hours so I'd say it meant hours. I've gotten a lot of use out of mine. I did find the batteries difficult to change. I broke the clip hinge twice. So be extra careful with that. Otherwise, a lot of light coming out of these puppies. I use two on my visor when I run at night and can see everything.

I ran mine for 2.5 hrs on the brightest mode, just to see what it can do. Didn't see any drop in intensity and still had battery left. How much don't know. My other lights are over $200.00 each so was real impressed with how long it lasted so far.

I used to get 2.5 hours but I've now had the light for a couple years and am getting 1 hour. So I ordered another one just now. The light still works great, I'm tempted to take the battery "pack" apart to see what it is and maybe go buy some replacement batteries for it.

Battery life around 1 to 1 1/2 hours depending on features chosen. Proprietary , but I STRONGLY recommend that you spend another $10 to buy a second battery from 3rd party vendor that has almost double the inherent power. That will last around 3 hrs. With factory battery and sevond battery you get a total of approx 3-4 hrs. In short, don't trust factory battery alone if going on snorkel trip.

I use the 4 ah battery for campin trips and usually get about 16 hrs at a moderate volume. My little 1.3 ah batteries make it about 4 hours

My Mom uses the Inogen One and gets about 7 1/2 hours at 3 liters from an 8 hr battery.

Try Energizer Ultimate Lithium batteries ... I find they last the longest for the long haul. Don't do videos myself so cannot say that this will be an improvement; but it is worth a try.

I get around 8 minutes of flying time with the standard batteries. Life shortens with dramatic maneuvers - rapid altitude, extreme banking and reversing, etc. Larger amp batteries are available, but I don't have any experience with them.

Milliohm hours deals with longevity, and depending on the flashlight it won't affect brightness. Most flashlights won't allow the brightest levels when battery starts to get low. Also the quality of the batteries and charger had an impact. My boss had a crappy 3600 mAh battery that lasted half as long as my 2600mAh Tenergy, both 18650 style. I would say that the 18650's are a better option than two 123's, but some flashlights won't take the slightly larger 18650's.

Joseph, I've never gone 24 hrs w/o a charge but the light lasts a long time. I run it on stone mode which I sense consumes lots if battery(while riding for safety) and it lasts for 3-4 hours no issue. I often do that 2 days in a row and then connect to the charger after the second ride. There is no "meter" telling you where you are on the charge and it's better to have and not need than to need and not have. Finally, a bunch of my buddies have the same light and it works well for everyone in my group.

I've had a couple of these and even when new I don't get more than an hour out of a charge. Currently it's about 30-45 minutes. I've never found the batteries to replace the original and my belief is they aren't replaceable. I just buy another WLB26B since they are relatively cheap and I like them because of the light output.

Hey bro...i just got mine yesterday and I've used it for so far 3 to 4 hours...and it works well...I'll make sure I put it up on exactly how many hours the batteries will last...

I'd say mine lasts just under 3 hours at the lowest power levels. The battery is easy to remove, so you can always buy a second battery to double your life.

I bought a set of Tenergy 18650's and I let the headlamp run on low for 14 hours before I got bored and shut it off.not sure how much longer it would have gone.

The boys get about an hour to an hour and a half run time. I have had issues where I thought something was wrong with the battery and it was the forward reverse switch going bad. I had to disassemble and file to remove pitting from the points. Also my connector plug for the battery seems to beg eying warm according to the discoloration and deformity of the plug.Hope this helpsRobby

The stock Nimh battery lasts about 12 minutes on a full charge. I recommend upgrading to lipo power asap
