Welcome Dahnade!
Good to have you here!
Problem is that high current drivers are not something made in volume - most of them so far are hand built by people in the US/Europe who expect to get paid a decent rate per hour. This means they are horribly expensive. To get the best out of an SST-90 you ned 9-12 amps output. You cannot build a cheap driver that will do that. And the LED costs around $30 on its own.
Aloha and welcome to BLF Dahnade!
Thank you for the warm welcone! It's nice to find a place where people know what they are talking about. Well, that certainly puts it into perspective as to why they are expensive. Like everyone, I am waiting for soneone to try the X6. For a long time, I always thought the led lenser x21 was the best you could get. I am glad i found the sr90.
I had in my had the led lenser p17. For the price it is really a bad flashlight...
Yeah, it is overly price! It isn't regulated to start off with. It's performance is average, but the actual build quality is not too bad. I brought it because I hadn't really see anything better at the time, or didn't know of anything better. Now, I want something serious.
I don't know what the problem is with obtaining the Trustfire X6?
I have had one for over a month now. I too waited to see a decent review, but none were forthcoming, so I ordered one anyway (two actually, a friend of mine wanted one also, from www.sz-eyoung.com ). Paid through the nose for EMS shipping, but was worth it as another associate who ordered one from DX around the same time is still waiting to receive his.
As for the light itself. Well made and assembled, at least as well as a lenser (yes I have a couple of those also, M5 and P14). Heavy, the balance point is just behind the heatsink when loaded with batteries. Of the 3 output modes (I don't count the useless strobe and SOS modes), Low -.18 Amps at the tail, Med .8 Amps and Hi 2.35 Amps. 2.35 Amps would equate to about 27-28 Watts (3 fully charged 18650's = around 12V under load).
I have a Fenix TK-40 and Medium brightness on the X6 is about the same as the TK40. Hi is nice and bright, and the colour is good also, not noticably blue or greeen. Hi setting is a bit bright up close as it ruins your night vision. All in all, I don't regret the purchase and neither does my friend. I don't know how it would compare against the Olight sst-90, but it sure is a lot cheaper. Make sure to get an extra set of 18650's as the runtime would be about 1 hour on hi and they take quite a while to recharge, especially with one charger.
Ouch! 
I'm glad the guy didn't get hurt. Man, that looks pretty bad.
To be fair though, these things happen - just like KaBooms and slamfires. In a perfect world, they shouldn't but they do. We all take chances with our hobbies and the more you push the envelope (whether it's driving a LED hard in 3*18650 configuration or using handloaded ammo), the more likely it is to blow up in your face. Sometimes quite literally. :(
That's why i always disliked more than 2 18650 in series. Even 2x 18650 aint 100% safe but statistically and with proper care it should be reasonable.
The above picture looks pretty bad! I have seen some pretty interesting pictures of HID lights+batteries going bad. I finally took the plunge after 6 months of contemplation and attempted justification - I purchased a olight sr90 and I am now waiting for the beast to be delivered. I am just glad I have a very understanding other half, but then she can now buy a $400 hand bag if she wanted lol

You haven't experienced a glock .40 KaBoom, have you? 
[O.T. - Knock on wood, I've had one and only one KaBoom while reloading....It's disturbingly easy to double charge Unique in a .45LC case - Thankfully it was in a Freedom Arms revolver so the only damage was done to my trousers!]
[OT]
Not personally, thank God but you know how these things go - spend enough time at the range and it seems like it's a daily occurence and Glock went into the business of making handgrenades. ;) And I definitely know what you mean with regard to reloading. For the most part, I'm a pretty laid back guy but something about reloading brings out the OCD in me and that's when I start to triple-checking everything - much to the amusement of my wife who thinks it's hilarious when I turn into Mr. Uber-Careful. The thought of having a gun go kaboom in my hands just scares the living crap out of me.
Truth be told though, I wouldn't hesitate to grab a Glock to defend my family from the advancing zombie hordes, should the feces ever hit the rotary oscillator. I'd prefer a longgun, of course, but considering that there's millions and millions of tupperware guns chambered in 10mm, .40 and .45 ACP/GAP out there with a bajillion rounds through them collectively, I'd be more concerned about losing a finger to the wonders of Chinese quality control. :D
It is indeed worrying about these events. Maybe there should be a deliberate week-spot in the casing of these multi-cell flashlights. However simple mistakes can occur.
(From CPF)
Let me elaborate on the scenario:
Use LiMn IMRs?
All my batts, I check with DMM after every discharge and another time recharge cycle. The DMM is always just beside my PC, and the alu boxes which stores all the lasers, flashlights are beside the PC. I have never skipped this stage, even with my NiMH and SLA. I rely on NiMHs and Li-ion professionally for one of my incomes (photography). Even with 3 digital bodies and 9 Li-ion, you can suddenly run out of power due to a simple "mistake" and on a very demanding shoot (say you are relying on a power sucking body/lens with stabilisation and always AFing and LCD chimping....or some videographers use them to take video which really impacts battery power). I really want to carry the charger, but my darn bag is really too packed.
With Nikon original Li-ion packs and Nikon charger, the LED could stop blinking indicating a full charge, and yet when you measure it the thing isn't fully charged. You can see the same thing in the cam, like 70% full or something. This happens with the older cells....but you still can use the cell.
If you will, having a backup for the backup for each of the bodies including the backup for the backup body, still does not mean that the setup is 100% foolproof. When i was younger with more energy, there was once in 4 consecutive days during a date period which was extremely popular for weddings, I did 4 full day weddings (ie morning session and then be back at night for the dinner) with 1 x short 2-hr solemnisation session squeezed in for the afternoon. You don't even have time to charge them up. LOL!
CPF's Throwjunkie measured 2.9A at the end with IMRs. That's nearly 9A at the emitter before losses.
I like what old4570 said (the guy knows his batteries man!)
Were the batteries fully charged :
Did you match the batteries for current draw :
Did you check to make sure the batteries were not faulty in any shape or form .
Multi cell operation requires care and knowledge , especially for the batteries .
If you failed to use due care , then this is operator failure .
1/ Make sure the batteries are all charged to the same state [ voltage ]
2/ Rest the batteries after charging for at least 1 hour and test voltage state ..
3/ All cell should match
4/ Test current discharge in another light , they should all be close
5/ When using a multi batt light , often test batt state to check for even discharge
6/ Buying cheap cells means you may need to take more care matching cells
7/ failure to use due care , failure to educate yourself to the correct use , may result in possible problems , resulting in possibly anything but the operator taking the blame .
Hi,
I'm looking to buy a TRustfire X6 SST-90 torch.
Where can it be bought at a reasanable price as I see all kind of prices on the net ?
Regards,
Stefaan
Ric of CNqualitygoods can hook you up with a good price. 120 bucks.
Don't forget, you have to pay for shipping 
But Ric is a reliable guy!
Well, i cannot reveal all the secrets online! I can only say, get all your stuff from Ric, he always gives a good price.... DHL pricing is good actually.
THanks for the replies guys.
I have found his website and I have contacted him to ask him how much he adds for shipping.
THanks
