How long is the battery life / led life span / light distance?

Not so sure about battery life. I have a couple thousand trigger presses and the batteries are still fine. Distance is much further than you would need.

Depends on your light (LED vs Incasescent), the lumens, and use... Could range from 180+ hours with a 15-20 lumen LED to just 2-3 hours with a 120 lumen incandescent. Check out the lumens factory message board for more details...

Hi, this headlamp is powerful! It shine lights from my apartment's balcony across to next block which distance is ~20m. Battery life should be good, mine is still shining brightly from my 1st use which is a couple of months ago - anyway LED torchlights consume low energy. I find this headlamp a very good buy.

Should work fine!, its a 12 amp hour battery, so if the light is 1 amp (i doubt it for a LED) then theoretically you would have 12 hr.

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.

I have used it only for a few hours and so far have had no battery issues. The LED bulbs draw very little current and the batteries should last for quite some time.

The distance depends on ambient light. You get 150-200 feet. It's ok. I'd pass and get something else. I've had mine for about a year. It's ok, and good for the price, I wish it were a more focused beam and less flood. All led naturally provide flood aLight sound the beam

Hi there, the included battery lasts approximately 3 hours on high, 5 hours on medium, and 8+ hours on low. After these points the light intensity will drop significantly but will still run for several hours before going out completely.

I have had mine running for around a year almost constantly. LED's are rated for anywhere between 2,000 and 20,000 hours. So to answer your question, a long time!

Don't know about the LED lifetimes, specs say they last a looooong time. However, this unit was defective as it came out of the box. I.E. the "Mode Switch" did not work to switch from 'AUTO' to 'OFF'. It is always in 'AUTO' mode.

2 hours with all 48 LED's is about the max depending on the amount of sunlight it gets between uses, it takes a full day of full sun exposure to fully charge so anything less then that will shorten the duration

I haven't tested it (Thankfully) but I think I read in the packaging that it would last up to 48 hours. They are really fine LED lights so I could imagine it would last several hours for sure.

I believe that at 100 continuous Lumens you will find battery life around 10 hours or less!

I think about 50 meters. The light is very brilliant and it has big power. I don't know about the time that the batteries live yet.

Mine has had excellent battery life. Still havent changed the batteries and its one of the best motion sensing lights I have

I have not actually "test" how long a full changed battery can last. But after I used it for nightly walk several times a week ( not on for all the walk, only a few minutes per walk, but when it's on it is with full brightness ) about three months later I found the brightness is weakening. I know it is not a very scientific way of "testing", but that's what I know about the battery. It is decent but not great as far as battery usage goes. Hope it helps.

Honestly, it lasts quite long. even with the crappy brand batteries the mouse came with it lasted quite a while. and in defense of the LED lights, they are cool as hell, and still do not drain the battery that much faster (depending on the battery you use).
