The J18 is insane though with the IOS driver, and KK cells - 5,500 lumens I measured... DayLighter has it now, but I got a J18 and the IOS driver, waiting...

I had mod a J18 with a new 7x board from Kaidomain, 3 MNKE 26650 ($15 each). It is definitely brighter than a stock 9xT6 ak47. Since the ak47 yields probably near 3,400lm, I’d say 5,500lm is about right for the mod’d J18.

I bought 10 of 9xT6 to distribute among people I know. I did mod one of them with a 9x board from Kai. Ran tested it with a 7.5amp 12v Power supply and with the MNKE 26650. It runs very hot quickly, but yield brightness just a tad brighter, if any, to the mod J18. So considering its larger size, power drain, cost, yielded perceived brightness, the J18 is the more worthwhile flashlight to modify.

Also, 2 of 10 ak47 did not work. I traced it to the center LED of the 9x set, on both. That’s a bit of strange coincidence, I thought. And the interesting part was that in this 9xT6, the LED star was labeled “XML U2” ! On the J18 7xT6, they were labeled just “XML”. So if the U2 is marketed as 17% brighter than T6, your eyes can barely tell.

Anyway, the stock 12x or stock 15x on just the same 3 batts 26650 would just drain it faster but shouldn’t noticeably brighter than a modified (and smaller to carry) J18.

We spent a weekend at the beach in FL, the J18 is so impressive as did the ak47. They’d sweep the low tide beach from easily 100yrds away, revealed fishermen in the dark. That was illegal for them to run net on shallow water so they did it at night. While impressed with the flashlights, They requested me not to attract cops attention to the area. LOL

You’d be happy with any of these lights, I believe. I just pointed out trade-offs of efficiency, price, size and resulted light perception.

BarrelMount - real good info there... With TF 26650's, I measured 5,000 lumens at 30 secs, and that is plenty enough, and yes, it heats up pretty quick.

photon1K - it's the only 7 emitter driver IOS sells: http://intl-outdoor.com/boost-7led-3-modes-23-cells-input-circuit-board-p-545.html

We think it's the same exact one KD sells, about the same price. Mode switching is slow and you weill get a buzz/humm on med and lo modes.

The later versions of the AK-47 is only about 32 watts with the low power driver they ship it with now. The IOS driver installed in the J18 should be about 52-55 watts, so that’s a big power boost and makes a big difference in output.

1. Did you use the heat transfer gum paste between the board?
2. I think it has an auto shutdown feature when it gets too hot. If that was active, it would be impossible to fry if use within power supply spec.
3. High batts drain. Charge your batts again. It could be protection circuit inside a batt shutdown.

Fwiw.

Wow, crap! Maybe those KK's were too much. Let me know if you want me to take a look at it because I got a spare driver, or I could even swap in the original driver to get it working. Hhhmmm... I think other guys were having issues with these IOS and KD drivers - can't recall details...

The gum paste? Think I used that thermal pad thing it came with between the boards...

Yes, thermal pad…. I couldn’t think of the name.. :8)

Price has dropped to $97.00 at Lightmalls and $98.00 at Manafont. Guess these haven’t been selling to well.

It may be a business strategy to sell cheaper flashlights that require more batteries, and make money on battery volume….

Waiting for my last Sony 26650 50A battery and will see if the light handle 5 of them!

The Reading I posted was With the driver installed and 5x battery.
It is a driver for SST 50. I also use this driver to my 12X t6 lights. Have try to install 4 of the KD 9A driver but all this driver died or dont work.
The Board is big so you has to remove the treads to get it installed.
It is the batterytube who fastend the driver. Use it with thermal paste and not use any spring. The driver is designed for up to 18volt input. The tailcap is about 4A with 4x battery and 7A with 5x Sanyo 2600mah.
Here is link to the driver. This guy deliver now tiny driver Board for SST led.

I did a couple (J12 & J18) for a forum member and it took a nice tug on the spring along with some twisting to get the spring out.  

Mountain Electronics : batteries, Noctigon, and much more! What's new?

TR-J12 or TR-J18 isn’t difficult to pull the drivers out.. I was talking about the drivers on the 15 LEDs light Smile

Wow.  Less than $4 per xml2 emitter.  Sure wish they would make these long lights with side switches.

So what does this light need?:

  • I think I read 18650 said there are some open spots under the emitter base.  So copper sheet inserts to get the heat to the fins.
  • Copper plugs through the one large emitter base
  • Better driver or maybe a driver mod?
  • Side switch mod (not an option on a light this long)
  • Dedome the 3 center emitters

Sounds like a totally unnecessary, but fun project.  I really like the form factor and size of that 12 emitter that RaceR86 modded, but with stock xml2's for $58 this one is looking irresistible to me.  Anyone got a better bang for the 15 emitter buck option?

I bought one of them a while back. Not terribly bright and the driver died. also it has one round aluminum star and it’s hollow under the star and around the edges where the emitters sit. The star is sitting a a large donut. I filled the stupid hollow donut in and now I’m looking for a new driver. But I have a feeling I mostly bought some cheap XM-L2’s.

I’m a junky, I mod lights so I can sell lights so I can buy more light to mod so I can sell lights to buy more lights to mod.

If you wire the leds 5S3P, a 5xT6 driver will work, or the extra voltage of XM-L2 will kill the driver?
