Does it really last up to 24 hrs on a single charge? Does it gradually dim or just die completely?

Yes it lasts longer, I did a 10 hours long ride with this on my bike and on full fire(Constant lighting). and even after that it lasted for couple more weeks for 2 to 2.30 hours rides. It gradually dims while its running out of charge.

Dunno. I've only ridden in the dark no more than a couple of hours at a time on each side of daylight. But really, man, within 24 hours you should get you some sleep; unless you're nyctophobic, then keep a wooden stake handy. Holy water may help, too.

It gradually dims. I have used it several times for 2-3 hrs each without recharging. I cant imagine needing it to last 24 hrs on a single charge, but you could get a second battery and swap it without removing the light from the bike.

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.

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.

note that battery life is specified at minimum backlight ; i ran mine for 5 hr 25 min , then i recharged even tho it was still going. i imagine those who got 4 hr. were using the default backlight setting.

It dims.(not like huge bright OFF) My battery lasted 2 years with almost daily use.

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.

The main led light on the corner will glow blue while on, red while charging, and purple while on and charging. When just charging it will turn off completely when full or to blue when done charging while on. I believe it will last aprox 10 hours?

When it is fully charged the light turn into green and stops. I don't think there's any problem in living it more hours connected... I have forgotten it some times charging of r a day or more and nothing happened...

From all the way dead about 6 to 8 hours for a full charge. When it is charging there is a red led, and when it is fully charged it turns blue. It works great!

First, I haven't actually timed its duration. However, I do notice that the intensity decreases when you switch to nightlight mode. I believe it should last longer because of this, but cannot confirm.

Not very long, We've gone through 2 of these things thinking maybe the battery was bad in one, but to no avail, both seem equally bad. There seems to be no indication that the battery is fully charged, the charging light stays red from what I can tell, I've charged it for 12+ hrs, take it off and almost immediately the battery percentage drops to 2 bars. All in all the battery lasts about 4 hrs in a silent house. If your child cry's a lot I'd bet you get less.

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.

I can't tell you exactly since I usually keep it on for no more than 4 hours at a time, then I will recharge it.I've had it on for 4 hours straight at the high setting without it dimming at all. I suspect I could get at least 6 hours at the lowest setting.

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

When it is fully charged, it lasts about a week, and then the battery loses one bar. I presume it can go a month and be just about ready to "die." It never actually "turns off" otherwise--the clock display is always on. But this is just in standby mode, without using the features.

Very rough estimate, probably around 10 hours till it's completely dark... that said, it depends on which setting it's at (there are 3 brightness settings), and it doesn't just go dead, it gradually gets dimmer with time. I have not had it actually turn off even after probably more than 6 hours of use over a long period (i lost the charger), but it definitely got dim. I'd say you have a good 4-5 hours that it's "strong." For what it's worth, it can get power/charge from a USB port on your computer in addition to the wall outlet.

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'm not sure how long it may last but it depends on the settings of your pc. Example your brightness and power management!

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.
