Got one today for my friend.

 Of course had to test it before delivering it Smile

 

Tested it against UF-980L and I got to say, it had tough company to start with...

On a shorter distance, say 100 meters, it is easy to notice that STL-V2 has tighter spot and more lux.

Then if you compare an absolute throw in meters, there´s really not THAT astonishingly big difference.

STL-V2 throws further but after 980L it does not make my jaw drop that much. Could the difference be something like 50-60 meters? Hard to say, I don´t have a lux meter to leave up there to test.

 

It is now 0°C and RH is at 93%, I felt like the beam itself in the air was blinding me. 

At this kind if weather, I would say I saw it doing maybe 200m+, can´t say very accurately. Measured only by cars speedometer.

I was reading throught this topic - this Skyray has 2 group of modes?

loosen the body from head slightly to go to 5 modes and tighten for 3 modes

You know what's funny? I've had mine for a while now and I use it all the time, yet I never realized it had two groups of modes. Big Smile

I have always liked that feature on my Fenix lights. Anyway, thank you very much for an outstanding review.

Has anybody been able to compare STL-V2 performance with Crelant 7G5 yet?

Well I have a Olight M3X which this light here is pretty much a clone of.  I have a Crelant 7G5 coming.  I'll let you know who the winner is?  I say it is going to be close.

WIll this light be brighter on 4X16340? Anyone tried it?

No, it won't be brighter, coz it is fully regulated.  BTW, can it take such a high voltage?  Had the impression that it can only take 2 cells.  1 cell also won't work.

Yes yes, I know, digging up old threads and everyone has this already on the shelf...

 

I have a mild rant on these.

Battery tube is short. You can barely fit Xtar2600s in and that barely means hard pressing Flat Stare

If you want them to be comfortable, you´ll have to leave either the tube or the tailcap slightly loose...

Any real world experience of running STL-V2 on 3x16340/18340 vs. 2x18650? How's the heat generated or runtime - and what about the reliability? What brand/type of cells have you been using?

tried 3x16340s but never looked at runtime. also had 2 18500s without the extender. 2x18650s will give  the most runtime due to capacity as it is in series at either 2 or 3 cells.

I've got a STL-V2 ordered from DD in November. Just wondering whether somebody is able to confirm the existence of Low Voltage protection?

I'm asking this because I was running it on unprotected batteries (Trustfire Flames 2400 also from DD) for a while and after checking the remaining voltage of the batteries I had to carry the other one out-of-doors in a hurry because the battery was hot and the voltage was just above 2V. The voltage of the other one was 3,5V at that time. On the other hand I also wonder whether this difference in voltages makes any sense because the batteries are in a series. Could there be e.g. such a huge difference in the internal resistance...

From the numbers up top its 2.99v per cell. you probably had a weak/defective cell there and probably advisable to dispose of it.

^ OK, thanks. So it seems that if the other cell is not good the LV protection did not kick in even the total voltage was less than 2x2,99V at least in this case.

 

I was actually running STL-V2 for a total of 120 minutes on high (12x10min, 5min break in between) and it was still going quite strong:

BTW. What budget (un?)protected 18650 cells would you recommend when taking into account the STL-V2 stock driver i.e. quite low current and the existing low voltage cut-off feature?

What price? 6$ you have protected Hi-Max 2600 (+shipping) which are ok, cheaper you may get 2600 unprotected sanyo (shipped) and that't it I think.

I got my STL today, at home we'll se what current we have there, 4A in led will warm it up a little, hope that new KAI driver fits there Smile

Does this flashlight has low-voltage protection????

For my copy, yes.  I was testing some 18500 IMRs this way.

BTW, having LV protection does not mean it is safe.  The driver (budget driver to be exact) can still go POOF and give you a dead short. Probably IMRs would just fry something, but regular Li Cos have a high chance of venting.  Not all batteries will vent of course.  And that is still a persistent risk.  I know you din't mean it that way, but just to say it out loud.  Smile

Quite expensive shipping. Based on latest review Trustfire "3000mAh" are decent cells, real capacity of 2500-2600mAh fot $12 shipped/pair.

We need a GB from Dinodirect!

But seriously the TF Flames 2400 latest ones that came to me and Cheap Thrills from Dinodirect, all got very close to 2400mAh @ 1A. (Benckie's got a few which got close to 2500mAh) The SKU number is different from the batch that some folks had "issues" with ie unprotected, which i wouldn't complain as they were "free/giftcarded". Even the 8 unprotected the one which i randomly picked out to test got 2498mAh.

I would spend 12 bucks on these 3000mAh cells, if they do a real 2800-2900 like the NCR18650 which i tested as well.  Else 13 bucks for 4600mAh worth of 18650 juice from the TF Flames 2400mAh is better. Still runs a very long time in most lights in med/low, more than most would ever need, and 2 pairs in the STL-V2 would last you for a week's of blackout. (spread this over multiple flashlights)

 

TF Flames 14500 and 16340 i've got over 700mAh.  So far all my TF Flames branded stuff are the real deal.  So i'm really waiting for HKJ's word on the 26650.

SO, if I understood correctly, it has low voltage proteciton, but it is not high quality driver so possible that it wont work... (than maybe PCB on battery will work Big Smile

So, if flashlight suddenly stops shining, to prevent venting best thing would be to turn of the switch immediately?

To be little offtopic: My girlfriend recently returned me 504 R5 flashlight I have her, with trustfire flames from DD battery, she's quite clumsy with all these things and she wasnt careful about how to insert cell into the flashlight, so she obviously inserted it vice-versa, and the result was that she fried the LED. She probably turned it off and pulled out the cell when she smelled smoke (smell of burning, there wasnt real smoke) - what happened in that incident - there was a danger of venting too? Protection o the battery kicked in only after driver burned out?

Yes, there is a possibility that a budget light driver may present a dead short if it should ever fail.  The Sky Ray 3800 triple XM-L is a good example, there are still good copies running ok here, but there are also a number of failures that presented dead shorts to the batteries.  Quite a number = i'd believe at least 30 cases here and CPF.

I am not sure if it presents a dead short in your 504 light's case after it was zapped with reverse polarity (human mistake), maybe you can measure the current draw with a DMM.  

Yes, turn a flashlight off immediately when it knoks out, should you ever have a mix of unprotected and protected cells. You will never know.

But, I asked yoiu tghat on some other topic I cant find now (I was looking for it today bit cant find it), there are hundreds of offers on ebay with  2X18650 flashlight, 2 18650 unprotected Ultrafire, for ecample, and really cheap double one channel charger. - so, im making theories, if Li-ions vent out so easily (volently?) - there would be some news in newspapers about it, no :9Because it woudl be happening every now and than - hurting someone etc. Hmmm... You dont have to answer on this theory Big Smile (now I rememberd there were incidents reported on TV about cell-phone batteries exploding etc, that wwas actual for rome time... Some low quality batteries...

There are some documented cases, a good high profile one is that Trustfire X6 and of course that Solarforce L1200 incan. Unprotected ultrafire and not sure which one. Happened just last year bro.    Even IMR could vent (Sony Knion, the green IMRs).

This is why 18650/18500/14500s are not consumer products that are sold in counters. It would be nightmarish for the manufacturers with regards to lawsuits.

Need help with drivers:

 

Are there any 4,2V -> 8,4V drivers suitable for this, with max two modes, no strobes?

Having problems to find any 8,4V suitable for this and enough juice for XM-L...

One of kaidomain will fit, I will try sst-50 driver, 3 xml driver is fine, gives more light, but overheats quickly without beeing sunk in thermogrease.

It is 3 mode, but you have to live with it Smile If you want to use it, you should put it all in thermal compound, otherwise thermal protection will turn on quickly.

I want to try http://www.dealextreme.com/p/8-4v-sst-50-5-mode-memory-circuit-board-for-flashlights-50025

It should be more balanced and not overheat that much, it lies on my desk, only time is missing to check it Wink

If you use the DX SST driver be sure to mod the tube on the end that changes modes with the old driver. Remove material at the end of the tube so the threads bottom out and tube end does not make contact with driver. Another solution might be an insulator washer. Not heeding this suggestion may result in a direct short. Don't ask me how I know this information. YMMV Smile

Yeah, thanks, I was wondering where this short is, because there is. Light is visibly brighter, on meter it is only 5-7klux, but it is visible Smile I will try to make a washer today Smile
