About how long is the battery life on this light?

If this is the Sima IR light the battery life is about 45min to 60min. You can plug it in and run it off the wall as long as you want, but the battery life is a little weak. It is a really bright light and worth the money.

The most I have had battery life is a little over 2 hrs. If you charge it and don't use it right away it will die. But honestly for the money its a good price. Hope this helps.

I charge mine every month the battery last quite awhile. I use the light as I'm coming out of work at night..I have purchased several of these for my children.

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.

Hard to say. I use it to light my keyboard when I'm on my computer in the dark. It's lasted me for about 2 months now, but when I use it I usually only use it for up to an hour and I do use it quite often though.

I haven't gotten that far along, but I'm estimating at least six months. The light only stays on about 15 seconds so it can go longer. I used alkaline batteries.

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

Not long, about 3 to 4 min. I have it in the garage. The problem is when I work in the garage, it turns off after a few min and I have to move around to turn it back up again. May need an alternative light source.

While I have not specifically timed battery life under high or low settings, my observations are that on the high setting, the light lasts on the order of several hours but the brightness decreases fairly early on. The light still provides useable light when the brightness wanes but do not expect the light to be "300 lumens" for more than an hour or two. I do not use the light on the low setting.

I have my time setting to allow the light to stay on only 3-4 minutes. I don't know how long it will stay on with a fully charged battery. The vendor could better answer that question. The light is bright enough to illuminate the whole front yard about 25-30 feet out to the road. As far as how many lumen s, that would be another question for the vendor. My limited contact with the vendor indicated that they know their product capabilities very well.

Not long at all. I had to stop using mine. When you put batteries in you get about 8-9 good hours, then light begins to dim. It is worthless!!

Its bright enough to read by, I'm not sure of the # of lumens, it gave off enough light for the room. I had it going for approximately 2 hrs on a full charge when I shut it off, so I cannot tell you how long it would run.

I cant say, it has never died on me, but then i dont keep it for long periods of time. I will say this, it,s the best light i,ve ever owned.

I've experienced no problems whatsoever with this light. No light drop off after 5 mins.or battery drain with the light off. Batteries appear to last about 6-8 hours continuous use on high beam. My light begins to fade just as the batteries are nearly exhausted, as you would expect. The light beam while brilliant has a short range, no doubt the cars would see you, but a bike light may work better for you.

it depends on how low the battery is -if only one red light is out -ive never timed it -but its about hour

Can't say because after several months this light is still bright. However, I have not used it everyday. I have used it twice a week for at least 1.5 hrs each time. Hope this helps.

I am getting about one and a half hours of continuous use, on high power, out of a 1.5 volt AA battery. You may get more time if you use the 3.7 volt 14500 rechargeable lithium battery. I love the light, it is very bright, brighter than my 2 D cell mag lite. I bought 4 more to give to my family.

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.
