I have tried 2 types of batteries (AA & C) in this flashlight - and it only comes on sporadically. What's wrong? LED bulbs bad?

I can't say that I've had any problems (have only used AA batteries). Perhaps you just have a "bad" unit?

I did not have that problem at all. Sounds like a defective product. I would ask amazon for an exchange....sorry for the late response...John

With all due respect, if you do not know what a 18650 battery is, you should probably look for another flashlight that uses AA or AAA. There are a lot of possible dangers associated with this type of battery if you do not fully understand it. There is a 4 dollar flashlight on Amazon similar to this that uses a single AA battery (search for "cree flashlight" - FordEx Group is a popular one).

I get the same thing. Basically I just think that this isnt a very good flashlight. I would certainly not rely on it. I would never recommend that anyone buy this flashlight. Also really surprised that so many of the reviews are positive for this flashlights. There are so many issues with it. What an awful flashlight.

I would suggest you make your own battery pack or buy a different light. My battery pack was dead on arrival. I haven't opened mine up, I started to pull the rubber stand off to get to the batt pack but it's glued on. It'll be damaged if I can't find another way. It's probably got 3 AA cells wired in series to give 7.2V. If I can't hack this to use AA or AAA 'Eneloop' batteries I will dispose of it.

I have 4 lights total and 2 have always worked perfectly, 1 has never worked and the 4th only ever "glowed" until last night, when I pulled it apart again, flipped switches and reinstalled batteries. Magically it seems perfect now. So, I'd suggest playing with it a bit.

As someone else mentioned in the battery test mode the Green (good), yellow (questionable/low) and red (bad) LED won't work, as those are meant for primary Standard primary batteries (AAA, AA, 9volt D and the like). I would just use the DC Voltage setting to test batteries other than standard primary batteries.

Sorry, can't help you with your problem, I bought this 9X TrustFire, but the seller sent me a different brand (CrazyFire) and it was bad from the start, there were only 3 modes instead of 5, hi-med-low and then it switched off when it tried to go to the next mode which I think it's S.O.S. I returned the flashlight.

Sorry but i have no idea where to get what you're looking for. The exact same thing happened to my Fenix led flashlight. I recommend purchasing a Maglite led or trying some other product with excellent reviews.

Sounds like you are having a heat related problem with the bulb itself. I'd say it's defective. I have no such performance with mine running on 12v marine batteries in my boat.

Send it back while you can. The batteries are expensive, not good for much else, and my light fried after a couple of months. I bought a Weiita H807 Starlight LED Headlamp, 300 Lumen headlight found elsewhere on Amazon. It uses good old AA batteries, provides plenty of light, and has been going strong since the first week in Sept. My son also has one of these headlights and we use them on a daily basis.

hi there, I bought 2 of these. Works very good, plenty of power for most jobs. As you can see in the left of the primary image, is the LED thing, in which you slide the battery. So you have to either use the drill, or the flashlight(if you have 1 battery). Personally not very impressed with the flashlight, not powerful at all. Recently bought a camp lamp(with 57 leds), from ebay for about 7-8$, it takes 3pc of AAA, and it works better, it is lighter, and you can hang it like a regular hanger. So don't rely on the flashlight..But the drill is awesome ! Got it for a deal here, was around 65$ with free standard shipping. hi there, I bought 2 of these.

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've had no LED (or other) problems with 4 Coast flashlights I've had over the last 2 years. Are you using the reular alkaline battery or the higher voltage rechargeable lithium ion battery?

My husband Chuck is a mechanic and he says it occasionally falls out of his shirt pocket without breaking. As long as it doesn't lamp tip first on the bulb it survives OK. When the light starts to flicker or seems dim, don't tap it or bang on it!Just replace the AAAA(4A) batteries right away. AAAA batteries are available at more stores than they used to be.Radio Shack has them. He is unsure of the lumens but it is plenty bright and the beam is concentrated enough for all uses. Chuck has used them for 5 or 6 yrs and bought 3 at a time because he loves them that much! My husband Chuck is a mechanic and he says it occasionally falls out of his shirt pocket without breaking.

I'm kind of having the same issue. The new batteries I have put in, die fast. I have been using regular store bought batteries. I know there are higher power batteries sold at places like Batteries Plus, that are specifically designed for high lumen flashlights. Might be worth looking into if you want to have optimum performance from your flashlight. I recently ordered a Zebralight SC52. Waiting on it now, but also ordered a $10 high powered AA battery to use in it. It was a battery they sell, and recommend. If you still don't have good light after trying these batteries, I would send it back, or try an exchange, because these Nebo Redlines are pretty cool. Good Luck. Hope I helped in some way.

A couple of the flashlights didn't work in my package too. I shook them up a bit and wiggled the battery and some responded to this. I didn't have the issue of any hot lights though.

i did same thing at first, & was sure I installed battery right. In frustration, I flipped battery opposite direction inside flashlight & it worked fine. It stil seems backwards to me, but I LOVE, LOVE, LOVE this flashlight! If yours still won't work after installing battery in all directions, then it must be a defect. Hope it works for you. It's the best flashlight I've used!
