new edc triple xhp70 not firing up
Hi all my friend and I bought this livht from Ric of edc and cnq qaulity goods http://www.edc-light.com/edc-light-triple-cree-xhp70-xhp-50-12000-lumen-... are the specs http://m.banggood.com/12000LM-Customized-Version-3XHP50XHP70-Super-Bright-LED-Flashlight-p-970456.html.I took the specs from banggood because they show better pictures and specs and how ric assured us he tested the lights before shipping them amd said they worked and when we got them I checked tail cap and drivwr with digital multimeter on diode test and it was good so when I installed the AWT 75 A 26650 nothing turned on ,I know the driver is a regulated and protected driver could to much amperage Set the protection on?I am bemmed we were both looking forward to our new mega torches any how here are the batteries I tried to use : content://com.sec.android.app.sbrowser/readinglist/0505201921.mhtml please any I dead would be GREATLY APPRECIATED!

Try completing the circuit at the tail with a DMM instead of the tailcap and see what that does. Are you using button-top batteries?

Does the light have a spring on the positive side?

Yikes! Quite a lot of money to pay for a light to not have it work out of the door. Sad

Ric does sell good products and has for a long time. Here's what I would do. I would take the body tube off the light and stand the head with the driver up, so I can get to it. I would take my cells and use magnets in between them and set them together, on a bench. Than I would use magnets on each end and take two test leads, with alligator clips on them and put the clips on the magnets, so you can use the other ends to clip against the positive and negative right there on the head. You can meter the leads that way, before testing and make sure you have voltage. If you do, then use them to test the light. If it does not turn on then, it's bad. If it does, then there's an issue with your cells when they are in the body, or an issue with the tail cap switch. You can meter the switch to see if it is bad or good.

Just so you are aware some batteries will not light up an LED or even a ICAN bulb.

I have a ROP Hi bulb That unless you use good quility cells it will not light up AT ALL.
I have 2× 26650s from radio shack that are not IMR cells therefor will not light the bulb. Same goes for a XHP70 build i HAD ended up making spacers to use 18650 IMRs which i have a lot of.
So before you jump to conclusions please try some high power batteries, I bet that’s your issue…
BTW thats a hefty price for a big @$$ 3x XHP70 light. i LOLd at the name EDC I pictured a smaller light for edc that had three XHP triple in it!

I agree with Old Lumens —looks like that light might take button top batteries—if you are using king kong 26650 the + is slightly recessed —I’ve had trouble with those in series—-

My buddy came and picked up the light and is returning both of them and is going to see about getting a refund he doesn’t want to deal with them if they are already causing problems ,so does anybody want to buy never cycled AWT 26650 75 amp high drain batteries cheap or trade for thrower?

If jumping from the negative terminal of the battery to battery tube with a small screwdriver doesn’t do anything to rule out trouble with tail cap, maybe a wire came loose during shipping due to a bad solder joint? I’d check to make sure driver ring was tight and grounding the driver properly first and then tear it down and check every solder joint for the wires coming from driver to MCPCBs. If I’m correct, the driver is a 18 volt buck/boost with the LEDs wired in series.

If the soldering job wasn’t up to snuff, all the banging the light received during shipping knocked something loose or it’s just a cold solder joint. It has to be something real stupid. I wouldn’t ship it back just yet. Try trouble shooting it first.

Try putting magnets between the batteries in case buttons aren’t protruding enough. Trying different batteries wouldn’t hurt either. Shove 3 of those plastic 18650 to 26650 tubes in there and drop some 18650’s in there for giggles.

A few things. First, this light is not and will never be a thrower.
I bought the ShengJie with XM-L2 emitters and converted it to triple XHP-70 before Ric got these done. Mine does over 11000 out the front lumens. ( actually am doing this for a friend, so it’s not mine )

Second, those cells wont’ run it. Try Efest Purples or King Kongs. Even good 18650’s like the Efest 35A, LG HE 2 or HE 4, Sam 25R, any of those will do it.

When it come’s to cells, cheaping out is likely to get you no result at best, and a very dangerous result at worst.

FWIW, I paid $75 for the light originally, am selling it to my buddy for $120 making 11,000 lumens. This is measured lumens, not Chinese.

That link to EDC is a great price! That’s almost cost, certainly for us it’s cost, I mean, I bought the light for $75 and then emitters for $18 ea. and built the driver and it’s $120 cost for me to build one like this. They even have a reasonable lumens quoted! Pretty accurate, surprising!

I have to agree with what’s been said, something must have come loose in shipping. There’s going to be a simple explanation that those 2 lights don’t work, seriously. I’d start with checking a better set of cells, or maybe a power supply. Then I’d go ahead and open it up and check connections.

The light is well made, once I had it in hand I didn’t want to sell it to my friend. Even the stock XM-L2 light is nice, with a suprisingly tight hot spot. Really, I wanted to keep this one and will probably buy another to keep as a long life emergency flashlight.

LOL, I used a 17mm FET driver with a Zener mod, and made a dummy cell to fill in the 3rd placement, closest to the tail cap. The light works with 3 cells, but I believe it’s stressing the emitters and won’t do it myself. (My BTU Shocker did a little over 20,000 lumens with all 3 cells in series, but vaporized the copper traces almost to the point of annihilation and I had to rebuilt the carrier because of this) I don’t recommend running one this hard. Somethings going to give and monies will be wasted.

Between my friend and I that’s 2 and then Vnre and I used. Multimeter.on diode mode and all was good from tail switch to emitter I tried Samsung 25rs with a homemade sleeve ,and you can’t get to the emitters without damaging something. So that is why my friend who bought them is returning for money and my responsibility was to buy the batteries which h were the AWT 75 A s brand new 6 each

Did you look up the review from HKJ on those cells? They’re most likely your problem…

http://lygte-info.dk/pic/Batteries2012/compare26650/AWT%20IMR26650%20380...(Yellow)-Capacity-20.0R.png

Or HERE

A screenshot from HKJ’s site…

This is AWT’s 3800mA 26650, not the 4500 like you used. Everywhere I saw yours was showing $10 ea or higher. Maybe you got scammed? At any rate, this lower capacity cell shown in the test sucks at higher amperage and the lights creds show 3*6A, that’s 18A in my book.

Dude, the red lines are Efest Purple 3500mAh cells, the blue lines down at the bottom are AWT 3800mAh cells. Essentially, the blue lines show the cells dropping below the emitters Vf requirement almost immediately. Won’t run the XHP-70. I have no idea what the driver is doing in that light, if it’d help a lesser cell work or if it’d shut down due to “low voltage protection” under load.

Also, the cells you listed are not 18650’s. They would have much different behavior patterns, as all brands show with different cell sizes.

Tell where this going to turn into an argument anyhow I tried 3 Samsung 25 rs in series with a pvc sleeve nothing and then I. Checked 3 AWT 266t0 in series 12.67-12.7 volts and what I was trying to sy HKJ did a test on 186t0 high drains and it tested well so WY wouldn’t the 266t0s if can send HKJ a battery let hkj Test it if he wants I will because Iam curious to see how they do and the bottom lin e the lights are gone I don’t have them my friend took them back and returning them and also Vnre s light didn’t work either so all 3 lights failed?

Didn’t read the whole thread but I have one of these except with XM-L2. Protected batteries were too long and were shorting out on the driver. Had to use unprotected batteries and use a spacer(a few coins). Unprotected were too short without the spacer and protected were too tong.

No argument, just trying to make sense of it all. I know that you can’t look at the test results from one cell and expect the same from another from that manufacturer. It might do as well, it might not. Typically the bigger cells can’t do as well in total output, although they do have more capacity. The Efest cell is the exception.

At any rate, I still agree that it was probably something relatively simple to fix the issue. Shame y’all sent em back so quick. Oh well. Happens that way sometimes.

I got started modding with an HD2010 that didn’t work out of the box. Every fix I did the dang light managed to come up with another reason to quit working! So I kept fixing and kept fixing til it was finally satisfactory. That taught me a lot, took some time but gave me confidence. Smile Then Old Lumens did the challenge and I found that one can do almost anything if willing and patient. I’m still not an electronics guru, so the drivers stump me sometimes. I just yank em and stuff an 17mm FET in and carry on. Wink (of course it’s usually not that simple, but that’s the fun, the challenge!)
