so who owns this?

Hows the build quality? Anodizing?

Is it everything you hoped for?

I’d hate to spend 88 bucks on a light and not be thrilled.

Anyone have some good close up macro shots?

I’m waiting on a KD driver for my TR-J12. Not sure what visual increase this SR will have over my existing light before or after the mod.
Anyone have both?

My Soshine 26650 arrived yesterday so I could do some measurements:
Voltage. H. M. L
Fully loaded 6.2A 1.8A. 0.67A
11.8V. 5.95A. 1.8. 0.7A
11V. 4.7A. 1.4A. 0.55A
10.5V. 3.9A. 1.15A. 0.4A
10.1V. 3.1A. 0.95. 0.35A

And it’s bright, everything is bright. I have a 3 XML and you could see everything good during night with it but with this thing everything is bright. For example if you point on a car 40 m away the hole street in front of of you till the car is flooded. I checked the roofs and trees from my neighbors and pointed them in their Livingroom, I could see everything as if the sun shines right in there window.

And it gets warm/hot what we should expect from a 50W+ in such a flashlight.

The driver could be more linear especially in the mid low setting, the strobe and SOS is crap like every time.

I can’t do capacity tests of the soshine because my charger is only the 50W type which discharges only at 1A max. But I could load 3.5Ah in it after playing last night with my Baby, so I think that they are about 4Ah like advertised and tested from others. One of my soshine came damaged, the wrap is ripped…but I can fix it with some tape.

Interesting to see that the review on CPF for this light got 3700 OTF lumens. My ceiling bounce test turned out to be quite accurate.

Hi folks,

Man I’m so pissed right now you have no idea. I spent a lot of time installing my KD driver in my Skyray 9x T6, being very meticulous and all, only to realize this driver, at least my example of it, won’t work using 3 × 26650 batteries. Occasionally it’ll turn on using 3, but will only illuminate in HIGH mode and not change modes. But basically using 3 batteries it’ll simply flash for a second and that’s about it.

I tested it using only 2 × 26650 (Trustfire 5000mAh) and it works fine using all three modes. Funny thing is the original driver doesn’t work well using only 2 batteries. For this KD driver, I’m pretty sure the modes are 100%-30%-5% and no flashy modes.

I was able to determine the Medium mode (30%) is just slightly less bright than a Trustfire J12 on HIGH mode.

I’m going to reinstall the original driver tomorrow and just leave well enough alone. The Skyray 9x T6 was a powerhouse with the stock driver and really didn’t need anything more.

UPDATE: With 2 × 26650, I get 10.5a at the tail cap.

UPDATE #2: I ran the batteries down a bit and tried it again with 3×26650, lux reading jumped to 1850 lux.

The only readings I was able to get were as follows:

Skyray 9x T6 stock lux on HIGH – 1295 lux (3×26650)
Skyray 9x T6 KD 9x driver HIGH – 1520 lux (2×26650)
Trustfire TR-J12 Stock 3 × 26650 – 810 lux (3×26650)


I removed the spring from the stock driver and installed it on the KD driver as shown.


Here’s the Skyray all buttoned up with the KD driver.

hmmm

first thing that comes to mind, is defective driver, since the specs say 3-4 cell, and ~2x the wattage

second thing is protected batteries

I think hkj tested the tf protected 26650s, and he usually does a protection trip test, right?

but…even if the driver was trying to pull 100W from 3 cells, it’d be less current than you’re already measuring, so that’s probably not it

don’t suppose you happen to have 3 x cgr18650ch unprotected?

anyway, if you determine it is defective and they won’t let you return it, you could buy another, and return this one in its place….of course if it behaves the same, you’re out $40!

Hi Dt,

I originally thought it could be the batteries protection kicking it, but I’d expect that to happen with 2 battery and not with 3 of them. What do you think of the tail cap readings from my post #96 ?

I think it’s pretty awesome, and since I personally don’t like 3 serial lights, I’d use it that way!

but, I can understand wanting to be able to go to ray gun mode…since that’s what KD advertised…

their specs are confusing – ie 9v low voltage warning but range includes 6V (yes, i know they’re not mutually exclusive, but that’s a rare feature)

also, 3-4x li-ion, but max voltage 12V

I’d try to measure the current and voltage for the brief moment that it will run in 3s config.

Are the 3 cells you’re using fully charged ?

Maybe it misbehaves when the voltage is above 12V,
try cells with voltage below 4V

If it works it obviously isn’t a fix, but might explain things

Hi Sigster, yes they were fully charged, but I discharged them each down to 3.95v each and it didn’t make a difference. However, once it did turn on using 3 × 26650 cells and I was able to get a tail-cap reading of 7a on HIGH mode. The stock driver on HIGH was 4a.

Also, I tried using 3 other very new Trustfire 26650 5000mAh batteries that serve very well in my Trustfire TR-J12 and it didn’t make a difference. It has to be the driver. Thank you for your input and suggestions.

wow, pulling ~78W

if 80% efficient, it is making ~15W of HEAT

could be it needs to be potted…even though the described behavior doesn’t match KD’s description…

i’d want to confirm that as the problem before I tried potting though.

you could freeze it, take it out pop the batts in and see if it runs any longer. Even just a bit longer would seem to indicate a heat problem.

I have a different high power driver from them, and there were reports of it not functioning due to heat.

I potted it w/ 2 ton epoxy w/ alumina mixed in, inside of a copper pipe fitting.

that worked, but I calculated efficiency and it was terrible – i forget exactly how bad but i did post results here (maybe 60%?)

Hi folks,

Unfortunately I was getting pretty aggravated due to the problem I was having with the KD driver, and didn’t snap a photo of what the LED wiring looked like with the reflector removed. I’m sure anyone on this board would have appreciated such meticulous soldering using such thin wire.

I will say this much, the person that wired this light had to be a master at his or her craft. The wiring is so thin (wired in series) and so neatly soldered, I could learn a thing or two from this person about soldering.

It also amazes me that even with the super powerful stock driver in this 9x T6, this little wire can allow this flashlight to produce the huge amount of light it does and eat a Trustfire J12 for breakfast.

that is surprising – though it’d be interesting to find out if a wire upgrade would make the stock config brighter.

probably an awful lot of work though…

I have no doubt it would make a difference and seriously reduce the resistance in the existing wiring. If I didn’t love the light so much and didn’t care if I messed it up, I’d give it a try. But there would be a limit to how much larger the wiring would have to be in order for the reflector to seat back down correctly.

Initially when I had the light apart, I was going to replace the stock + and – leads coming from the LED’s down to the driver, but I felt it wasn’t worth it at this time.

I’m thinking this KD driver for the 9x T6 simply requires more power than what any of my batteries can supply. I tried it with my Redilast 3100 × 3, and within about 3 seconds coming on high mode, one cell tripped the protection. Unless someone else is willing to try this driver in their Skyray and verify my findings, I’d say just keep the 9x T6 stock.

Maybe someone with a descent bench power supply can test this in more detail.

Maybe just unprotected 26650s? The kingkongs?

It has low voltage protection built-in

you could hook some test leads up to your new lifepo battery, although I wouldn’t do it w/ a full charge…

Hi FM,

I was thinking that too, but at this point, I don’t want to purchase more 26650’s, especially since I purchase these 3 extra Trustfire 5000mAh cells specifically for this light. But thanks for your suggestion.

Hey Dthrckt, That might not be a bad idea. I can discharge it to an acceptable static voltage and give it a try. Thanks.

LOL…okay, I reduced the voltage on my shorai 14Ah battery to 12.5 volts and connected it to the KD driver. OMG, this thing was so scary bright, I’ve never seen a flashlight this bright, as least first hand anyway. After 15 seconds, I noticed a very small bit of smoke come from the driver and then it went out. I removed the driver and can’t seem to find anything burnt, but it will not illuminate anymore.

At this point, I’ll just leave it up in the air as to whether this driver was simply defective only when using 3 cells or not.

Tomorrow I’ll toss the original driver back in, at least for now, until I get a chance to order another KD driver for it. Thanks for all the helpful input. It’s always appreciated Wink

It was supposed to have overvolt protection so maybe it was defective the whole time.

Try getting a return from KD? Its unfortunate this didn’t work, but thanks for being the tester!

The funny thing is when I tried it with the Redilast 18650 3100’s, for an instant, the tailcap readings shot up to 17 amps, so I yanked the 12 gauge test leads off of it…LOL. I’ll put an order in for another driver this week and give it another shot.

Until I can get a replacement KD driver, I tossed the original one back in the light. All works great as it originally did and I’ll get back to this one in a few weeks and let you all know how I make out with it.

Just an update on the KD 9x T6 driver issue.

BLF member, Dthrckt helped me out on this one and fully encapsulated a brand new KD driver he had on hand in addition to replacing the thin wires with 20g of the good stuff. The encapsulation insured heat wasn’t going to be a problem.

Using my 12g DMM leads and 2 × 26650 Trustfire 5000mAh cells fully charged, I was able to get 5.50a on HIGH mode. My previous KD driver, pushed out 10a+ under the same conditions. So that first KD driver was seriously screwy.

Now I decided to try it with 3 × 26650 Trustfires fully charged. The light came on long enough to get a tail reading of 7a, which I believe was on HIGH mode, I think. Then almost immediately it flashed off, as it did with the other driver and would not turn on. I installed the tail cap and pressing the switch, it would only flash momentarily and turn off, same as the last driver.

So it only appears to be useable with 2 batteries and 3 makes it crap out. Seems to remind me of that issue with the J18, 2 cells great, 3 cells the driver goes screwy. Who knows if this KD driver and the driver for the J18 are similar in some way, or maybe coincidence. Maybe it’s not related at all.

My stock driver on 3 cells pulls 4.24a and produces huge amounts of light. I’m not actually sure if this KD driver on 2 cells pulling 5.50a is brighter. Maybe someone can chime in with the answer to that one, but my eyes may have seen it dimmer.

Anyway, if anyone is considering improving their version of the 9x T6 lights out there, for one thing, stay away from this driver. I’d hate to see anyone in our forum toss money away on something that is very buggy.

In my opinion, the best thing you can do to your light, if you’re bold, upgrade the LED wires under the reflector to 22g or 20g, whichever will allow you to reinstall the reflector properly. I’m sure that’ll really cut down resistance and push more lumens OTF. As it stands, the Skyray 9x T6 stock driver, aside from the blinky modes, is really great even as is.

To Dthrckt, thank you once again for all your help and hard work helping me with the driver. It looked like a work of art Wink

There are some similar driver out there with just a controller and a FET, direct drive on high. This could be an option for a defective stock driver….

Richie086, sorry to hear about what you’ve been through with this light but I wanted to thank you for putting the information out there and saved me the money/hassle of ordering one. I really wanted this light and I’ve just been dragging my feet on it but once I read your story, I scratched it off my list. Hope everything works out with the mods and you’re able to salvage it.

Thanks guys for the comments. If anyone does find a good driver similar to the stock driver, feel free to post a link to it. I wouldn’t mind keeping one or two around as spares.

Also, I upgraded the wires again on my DMM. Still using 12 gauge but upgraded to high end silicone wires with bare ends. The stock driver is back in my Skyray 9x T6 now and works great. With fully charged 3 × 26650 Trustfires, tail cap reading jumped from 4.24a HIGH to 4.90 High mode. So this stock driver really does a great job. I’m fine with it’s power levels and will be leaving it as is.
