CANCELLED -- Group Buy for Trustfire TR-S700

I'm no longer interested in pursuing this.


Group buy price is $116.99 if we can get 20 people.

This version has XM-L2 emitters, but it'll still say XM-L T6 on the side.  

I've been looking at this light for a long time because it has infinitely variable output that is controlled via a slider on the handle that starts at less than 1 lumens and goes to over 3500 OTF lumens with the older XM-L version, 3x 26650's in parallel, and anodized threads.  

 

The low mode should be lower.

How good is the infinite control on it though? Doesn’t seem like much area to work with on the slider? Am I seeing this correctly? 7 LEDS? This looks like a beast. I really like how the switch and handle combo, seems like it’d be easier to hold.

I have this light and the control of the switch is fairly good.  I can make it go so low you can barely see the LEDs glow and can put your eyes right to the lens and look at all 7 lit up.  It's a little touchy getting smooth transition at the lowest modes but is pretty good overall.

Mine stock made 3500 OTF lumens and modded with upgraded wiring from driver and on the LEDs as well as upgraded FETs on the driver it only bumped up to 3600 OTF.  If there is a secret to getting as much as the cells will give I have no clue what it is.  Richard (RMM) didn't think a resistor mod would make any difference at all and suggested the FET upgrade.  It did nothing as the upgraded wiring added made it go to 3600.

 

Edit:  Mine is an original that I purchased from FT as soon as it hit the market.

Hi Leafty, thanks for getting this GB going. I hope you don’t mind me posting this information on this thread. With the number of post about this light recently, I thought this information should be put in this thread rather than my inquiry thread I started a few days ago.

Also, thanks to member, Rollinstone157 for his assistance behind the scene. Lastly, member JohnnyMac for his initial review on the Fasttech website that put me onto this light in the first place.

These numbers and options are direct from Trustfire, nothing special about them, but the options are what’s important to me.

They are offering the light with the case for $87.38. If I want it with 3 protected Trustfire 26650 5000mAh cells (real ones) , will be an additional $16.50. I can always use these cells, and given the fact they’d be real ones, I’ll likely get them.

I’ve been given a choice of which XM-L2 LED’s, either 6500k or 5000-5500k. Well, I’m taking the NW XM-L2’s for sure.

The TR-006 charger for an additional $6.45, I have and don’t need it.
The TR-008 charger (chargers 3 cells) for an additional $18.26, received not great reviews from CPF, and won’t buy it.

I did specifically request DHL shipping, and due to the weight of this light and case, that’s an additional $69.43.

If I go for this, my total cost delivered would be, $173.31. That shipping price might be less, but I’m not sure.

The reason I’m considering an expensive purchase direct from Trustfire is due to being able to purchase the light
exactly how I want it with the exact XM-L2 LED’s I want. So it won’t require any upgrades whatsoever.

I also have 3 extra brand new KeepPower protected 26650 5200mAh cells (if they fit) and 3 extra brand new KeepPower IMR26650 5200mAh cells. So batteries won’t be a problem and why I purchased them ahead of time for this light.

Out of respect for Leaftye’s thread here, I’ll hold off purchasing from Trustfire unless GearBest isn’t willing or able to give us a choice on which XM-L2’s we can purchase. Thanks.

BTW, payments accepted are, you can choose paypal, T/T or wester union.

Unfortunately I just ordered one from FT and it supposedly shipped today. Bad timing but only $8.60 over the GB price but w/o the XM-L2 upgrade. If we can get it with the warmer XM-L2s I might jump in though.

JohnnyMac;

I thought that you promised a full review of this light years ago. I still cannot find it! Wink

Hi Rich,

Did you order it with some type of shipping upgrade? If not, using the forums coupon code, you should have only paid about $3.00 more than what’s shown in the OP. I was just wondering, thats all.

Actually as I recall I did use the coupon code so you are probably right about the actual price. No shipping upgrade but the shipment was delayed a couple of weeks as FTs stock status was incorrect and they did not actually have it in stock, thus the memory fade on the price.

Great, sounds like you got an excellent price on what’s suppose to be an excellent and beefy light. It can’t be cheap for any retailer to ship one of these in the case. It also looks to be the ultimate tail-stander with that excellent flat base too.

Doesn’t look like there will be any more takers for this light. I know this forum has had way to many GB’s lately and wallets need a rest.

I decided to make the purchase directly with Trustfire this morning. To get it custom assembled with the XM-L2 5000k color temp and real Trustfire protected 5000mAh cells that I don’t have to worry about being fake, makes it a great deal for me.

I’ll be sure to post about it and try to put together a decent review for you all. Thanks.

Here are some pictures of the TR-S700 from one of the vendors that might make this GB happen.

The low mode should be lower.

Afraid that spotlight style handled lights are a specialty format that only appeals to a limited number of people even though to me they are the logical format for larger lights. To me accessory spotlight style handles should be available for every light with a battery tube/handle that is 2”/50mm in diameter or larger like all four physically parallel battery lights including those that use a four 18650 battery holder like the Fenix TK75 and TK76. If this was a more popular light format then there would be more clamp-on handle accessories like the one that Nitecore recently introduced for their TM lights.

The TR-S700 is a limited appeal light for most people due to the sheer size and weight. It almost has to have a handle due to the diameter of the three 26650 in parallel battery tube. If this was a massive throw distance light offer you would probably be beating takers off with a baseball bat though to me a light with more flood is a more practical light for most uses. Also the fact that it is continuously variable output makes it very appealing to me. IMO it would be even better if the output was controlled by a magnetic ring so that it was easier to get an exact output level.

Gearbest took awhile to ship out my only purchase with them. They only shipped it out after I complained on here. I’ll give them another chance though.

Put me down too for this GB thanks leaftye

Per a USPS tracking email received this morning mine just cleared Customs in LA and entered the USPS system last night so I should see it by Friday unless they send it on a wild goose chase which has happened before.

id be all over this light excepth that after reading that johnny only got 3600 otf after mods.
if 6000 lumens was doable, id be on this list .
other than the cool switch, why would i carry something this big when i can just carry one of my smaller coke can lights that has equal or even more output.

IIRC Johnny also reported that the light had good enough heat control/dissipation so that it could be left on maximum pretty much full time if required. That is something I would NOT like to try with a ghetto blaster SRK or Supfire M6. I have a 6 LED SRK clone modified by RMM which tests as 5000 Lumens at turn-on, a Supfire M6 that does 4600 and a seven LED Supfire L1 that does 7000 Lumens at turn-on. All Ultra bright RMM lights but once the turbo timer kicks in they drop to <2000 Lumens.

For high output that is sustainable you need both mass and good heat paths from the LEDs and per my understanding this light has both.

@ rich: True about the power. I have cooked off a 7 emitter king clone once running it on high with no step down. All 7 leds slid off their pads and some of them died and went to heaven. Funny thing is I did not notice it to begin with though. But when I did and turned around I was just in time to see the last 3 go out Smile

EDIT: And make no mistake about the quality difference between this light and a king knock off. These genuine trustfires are a quality that is wayy up there compared to what people generally consider xxxxfire quality. Leagues above.

Hi there Ray,

I have to agree with RichWouldnt’s comments. True this Trustfire S700 is a large heavy light, but the proper heat sinking is one of the reasons I was sold on it, not to mention Trustfire custom building it the way I want. I also use my lights to tail stand, which this one would be great, but I sure wouldn’t use it to go for walks due to the size and weight.

Recently I purchased the high power SuperNight 12x (Lightcastle) flashlight. Simply using it for beam shots to post to the forum, the Fujitsu heat sink paste under the star already began to melt or loose adhesion, allowing it to slide around with the reflector removed. I guess that’s what 10.45 amps at the tail cap can do when heat dissipation isn’t great.

Richie086;

Isn’t that 10.45 amps at a nominal 12 volts or more or what was the voltage drop you saw? That would still be in the region of 100 to 120 watts of heat to get rid of from a relatively light weight light. No wonder things heated up in a hurry. IIRC I have also been reading of the springs heating up and discoloring on those lights. Sounds like they are NOT going to be examples of reliable flashlights except maybe in the middle of a Siberian blizzard in January which MIGHT give adequate cooling.

Hey Rich, I didn’t monitor the voltage, but the cells were fully charged to 4.20 volts. I used the new KeepPower IMR26650 5200mAh versions due to the protected 5200mAh Keeppower’s were much to long to fit properly. But I did get a tail current with the protected versions of 9 amps. But the IMR’s fit perfectly, so that’s what I’ll be using in it once I remove the star from the light and go with some Artic Silver or something.

I used the standard formula and came up with the following, 10.45a*3.8v*3=119 watts. Basically the same as what you came up with.

Sounds to me like some of the Chinese budget light sellers are really starting to push the envelope on output and need to start paying more attention to the basics as far as LED heat dissipation is concerned. Use copper LED mounts, smooth heavy integral mounting tables and have plenty of metal cross sections in the path from the LEDs to the rest of the head. Otherwise they are going to have lots of failures which will not help sales once the web starts reporting them.

For years we complained of underdriven LED lights from China and now we are starting to see the exact opposite in some cases it seems. Underdriven allowed for reasonable reliability even without the best engineering but at high output levels things need to be right or failures WILL HAPPEN. That includes the possibility of battery cook offs and explosions if people leave them in tailstanding turbo mode. Not good!

Rich, you’ve really hit the nail on the head with the above. In addition to that, they also forgot to realize they’ve overpowered some of these lights to the point, only the highest end IMR26650 cells can run them on HIGH mode.

I guess that old saying fits here, be careful what you wish for, you may get it.

My background in Silicon Valley was Reliability & Specification Compliance Test Engineering on electromechanical monsters for years, ie daisy wheel printers at Xerox Diablo Systems. Any one remember them? Electromechanical monsters that the laser printer and then the inkjet killed. So I know something of subjects like component derating, temperature sensitivity and it’s effects etc. Overall a LED flashlight is pretty simple in comparison.

Speaking of batteries does any one think that this TrustFire flashlight could come close to reaching full output with TrustFire batteries? Wink

I haven’t received mine yet, but I did want to see how it performed with the 4 different 26650 cells I have. The light is wired to have the cells in parallel, which is another thing I liked about it. I assume the Trustfire 26650’s would act as a single 4.2v 15,000mAh cell (rated mAh not actual) and simply share the 10 amp current load between each cell on HIGH mode.

The power output I come up with is, 10a*3.8v= 38 watt gross output.

Considering it’s rated to run on HIGH for 2-3 hours, depending on how good the cells are, I’d say on lower settings, this should be a real long runner.

This was the review HKJ did on the Trustfires, REVIEW TR26650

ok now theres an incentive . i didnt know that this light has superb heatsinking. thats what makes the difference.
since this group buy isnt a huge savings, i think id wait for richie to give us his 2 cents after he receives his light.
im curious to know what the otf lumens is after 5 mins of running it on turbo.

JohnnyMac posted a review of the light on the FastTech web site shortly after buying the light. I suggest you read it. Short but interesting and it has a Pros list which references the heat sinking and it is expanded on in the text.

I have no means of testing Lumens. I know what some of my lights output as I sent them to RMM for modifications and asked him to give me his test sphere results for all levels. The TR-S700 will probably make the same trip for wiring, LEDs and braided springs upgrades along with testing before and after.

I didn’t even check the normal price until blueb8llz said the GB isn’t much cheaper. If they GB doesn’t go through. I’ll still buy one for sure.
Want a light that can run on high for a long time.

Only wish it had a tripod hole so I could use it on a tripod when working on the car and stuff.
