How long did your original batteries last? Mine lasted only a few tests (&lt;10min) then only one solid white light mode left, until replacing batteries.

I have not had to use them as of yet. If you are using them as lights in a dark area or tent - you should probably have spare batteries around.

Hi Ted, The batteries don't seem to last very long. I have them on for at least four hours during my shows and I have to replace them every second to third show if I want the brightness, I do have then on full power. Hope this helps. Barbara

I've been testing mine since this question came in, 4 hours continuous use of the 3 LEDs since I turned it on (i.e. unplugged it from power) earlier today to do a test. It's still "on" and still quite bright after that time. I rely on these (I have 2 of them in the house) to come on automatically in an outage, and help me find my way to my stash of brighter flashlights and other emergency supplies. They do cast plenty of light for that and other basic purposes. If you REALLY don't want to be in the dark though, consider having additional sources of battery-powered light in your emergency kit. As we've all learned recently, it may be days rather than hours that you'll want some light.

Hi Deann, honestly mine only lasted 3months. Switch to turn on/off, and day/blue night lite started acting up. The only blue light would turn on, then only the day light, then NO light. Very disappointed, because when we first received it I gave it a positive comment & loved it. I guess, I got that one bad apple of the bunch lol. Good luck and Happy Holidays

Well, Chad. The ones i bought work Perfect, No Issues. Sounds like your problem could be a Ground Issue? I guess i would hook them up, one at a time, to a good 12volt battery. makeing sure if the problem follows the same light. then...take that light apart and look for any possible Faults?

Wel we don't run the lights all the time so I only know that I have only changed the batteries once so far. We run them when we have guests over. It appears that they last pretty long though.

wow- I've had different LEDs for as long as 4+ years now. None dead. I'd definitely contact whoever you bought it from. they should replace it if they;re decent...

Well let see.... I don't remember every changing the batteries since I put them in place, so if you can see when I bought them, not since then. Thanks for reminding to change the batteries. I do test then so I know they still work. One has saved me a couple times.

I work ten hour shifts and have yet to have had a need to run the light for longer than 15minutes. Additionally, I will toggle with the buttons and switch from one setting to the next and so on. I even play around with the strobe light function. I have not used it for longer than 15minutes at any single given time. Just to be on the safe side I always have the second battery in my cruiser. And I charge the battery every night when I go home. Hopefully this helps!

My last one failed after quite a long time, it just wouldn't go on, I changed batteries, tried to open it, but just figured it wore out. I just bought another one. So I don't really know why they fail. Sorry.

New batteries, flush it out. Or maybe that part of it just burnt out. Sorry..

I have just cause I had them from another light that I killed and it didn't seem to make a difference. I keep 18650s in mine just because of how much I use it around the house. Just bear in mind that it is NOT 1000 lumen by a longshot.

I had the same experience. It operated great for a couple of weeks. Then one day I noticed it was on in total day light. It eventually went out and operated fine that night. A couple of days later it just stopped operating completely. I just returned it for a refund. It's a great light, just what I wanted, and worked fine then just quit. Go figure????

Doito, went dead, no LED light indicates to me that your batter is nolonger connected, Check to make sure it has not disconnected, make sure it's not bad. Even new batteries are bad out of the box. I experienced this first hand as an electronics tech

Sorry to hear about the problems you encountered. I've had no problems with mine since I purchased it. Seems like you received two defective flashlights. Suggest you request replacements or a refund from the company. I have no other suggestions as to what's causing those problems.

Mine were a bit dim when I got them.. I just replaced them with another Double AA battery I bought at the store.. no special battery... after I replaced it,it lit right up at dusk.. stayed lit until morning. I've enjoyed mine.. they do shine brighter with newer batteries, any kind.

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.
