What is the approximate battery life at a brightness setting of 6?

It should be longer than 1 day in the field. I say this because I've left mine on at least 3 times set for a bright sunny day approximately 4 hours each time and haven't needed to change the battery yet. I go with other rifles and do the same also carrying spare batteries just in case. Just speculating, but I believe the long battery life is due to just a single dot illumination where other scopes light up larger reticles. Hope this helps you. I live this little scope.

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.

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've never done more than an hour at a time on maximum brightness, but I'd expect to get at least an hour or two from a fully charged battery

around four hours if you put the brightness button to a minimum since it's very bright anyway.

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.

one night we were doing a bbq outside and it was giving at least an hour of light: the light did not have full charge. the light is pretty bright.with full light it can give you a more than 1 hour i believe. but I don't know about 4 to 6. I don't think it is designed for this long or for constant light, This light turns off automatically if no movement.

Inherent brightness is controlled by whether on battery or not. As to ambient light sensing: mine works well.

Tested with a Kill-a-watt.55 inch 6000 Samsung LED.High power saving mode about 80-90 watts.Low power saving about. 150-160

Always keep in my jacket pocket and batteries have lasted 6 months so far with no loss of brightness. Never use it for more than 10-15 minutes.

You can adjust backlight of the LCD screen to save power + You can get an extra battery (4 hours)

The time greatly depends on the brightness of the screen. At a moderate intensity, I'd say 4 - 5 hours.

i am not sure..i would guess at least 3 years...As for how long the battery would hold a charge:Depnds on how you use it...I had the wifi on and was playing a 3D game for 2 hours with full display brightness and after 2 hours i had 40% battery left...i got tired of playing so I am not sure how much longer it would last.....you could set the display brightness to 50% if you are just browsing the internet and it may last 3 hours with wifi on.....

For me, Battery life lasts about 1-1 1/2 months on brightest setting and 2- 2 1/2 months on dim setting. I use as under cabinet lighting and turn on only when cooking, 8-10 hours a week. Overall, I am very pleased with this product and battery life because it is still a much cheaper option to buy batteries than hiring an electrician to install lighting. I would like to get rechargeable batteries to save even more! Also, the wireless feature makes the system look more sophisticated, my friends could not tell they were stick on!

William, thanks for taking the time to respond. I will also let everyone know what kind of battery life we observe. Best of luck to you.ww

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

Yes, about that long if you have the backlight on. I discovered that turning the backlight off (F1 key) will allow it to last all day on a single charge.
