~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Extended Review :
The flashlight itself :
Good quality reflector , producing a nice beam :
Lens aren’t AR coated , but “clear” enough 
:
Some words for the accessories included :
- Battery is a true 3000mAh protected battery , test showed 2.890mAh on Lii-500 (discharged to 2.8V not 2.5V that battery manufacturers rate the cells) .
- Charger provides 0.75A charge current , and termination voltage is 4.21V . Great!
- Bike mount accepts great variety of diameters , fully adjustable . It can also rotate !
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A Quick Teardown :
Head , tube and tailswitch :
Tube threads (tailcap side) , anodized and “square”. Note that it has an o-ring , and threads are well lubed :
Switch (regular reverse clicky) :
Switch assembly (classic & trustworthy little omten switch used) :
Flashlight head . You can see the driver , with the driver retaining ring and driver’s nice gold plated spring :
Bezel removed , no glue :
Flashlight head , no pill as you can see . Also , emitter mcpcb is copper (non-dtp board) :
Driver is a buck driver , that accepts single 18650 battery or two 3V CR123A batteries .
Modes : It has 4 basic modes , and a hidden strobe mode .
Operation :
- Full click enables/disables flashlight .
- Half click navigates through the 4 basic modes
- A quick double (half) click enables Strobe
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Measurements :
Battery used : Thorfire 3000mAh battery (the one that comes with the flashlight)
Lumens on highest setting : Approx. 940 Lumens
Intensity on highest setting : 29.5 kcd
Amperage Draw :
Hi : 2.9 Amps
Med : 757mA
Low : 90mA
Moonlight : 17mA
Runtime (tested) :
Hi : 60-70 minutes
Med : 150-180 mins
Low : 27 hours
Moonlight : 42 hours

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Conclusion :
The review says everything i think . A very good quality C8 : good anodization , anodized threads , a nice buck driver and the high quality reflector . 4 basic modes (and hidden blibky) , with nice spacing from moon to high , what else can we ask for ? Performance wise , it isn’t the most powerful C8 in the market , but yet has some great throw and a great looking beam . Check post #2 with an optional mod also 
thanks!
Flashlight was provided by Thorfire for review purposes . You can find this flashlight here (non-aff) .

3$ mod (well , some skills involved :p)
As i mentioned in the review C8s uses a buck driver . It is moddable , with only a resistor you can get a ~25% increase in amps LED gets .
Here is a pic of the stock driver :
The brown component you can see in front of the coil , is an R050 (50mOhm) resistor . By adding an R100 (100mOhm) resistor on top (parallel) of the R050 , total resistance reduces to 33mOhms .
Current without any mod : 3.25 amps (using VTC5A in all measurements)
Current after resistor mod : 3.4 amps
Current after resistor mod and spring bypass : 4.05 amps
Other mods i did :
Parts before re-assembly :
Dedomed LED in place :
Results time :
Stock flashlight : 29kcd
After mod : 82kcd
Total cost : ~3$
2$ for noctigon , 1$ for 100*R100 resistors .
Reflowing and dedoming the emitter needs some expirience , it’s a bit tricky … Thanks for reading
Beamshot @ 12m before mod :
Beamshot @ 12m after mod (tint isn’t that yellow/green , it was in daylight setting
) :
Both pictures taken with the same settings , iso 250 , shutter speed 1/30s .

Under construction, yet already looking good!
nice review man
Do you have a Convoy C8 perhaps, for comparison?

Sorry grammarlovers, I am a real King Typo.
I really like these lights. Thorfire did a great job with the driver, in my opinion. Perfect spacing, with a hidden strobe. It appears to be a slightly higher amp output than the models I have with the screw in pill, and aluminum Mpcb. I do like the new tailcap design. I’ve been waiting for a deal to come up on these new ones, for a while now (Barry, are you listening?). I guess I’ll just have to bite the bullet, and order one.
I have been buying their protected batteries for a while now, at first they were samsung ICR18650-30b’s, but the last pair I got were Panasonic ICR18650BE, which are 3200 mAh (and they test out to that).
Looking forward to pictures of the driver.
Brian
I have one Convoy , but it’s modded with xp-g2 .
As a host form :
Both flashlights have : High quality Anodization , Superb Reflector , Nice anodized threads on tailcap side , Retaining ring for the driver mount and high quality switch . There isn’t any difference in quality of those mentioned .
A nice addition is Thorfire’s tailcap (look only , no difference in quality or operation) , it has a unique design with cut-outs (allowing tailstand , and easy operation with the thumb) .

Beamshot of the Convoy C8 (Fet driver + xp-g2 dedomed) vs stock Thorfire C8s :
tight but very bright too (around 175kcd) .

Hey Dusty, what kind of price do you think a good deal?
Not Enough Great Lights
Thanks for the review, interesting charger, looks like a Xtar MC1. I like the matte finish of thorfire more than the convoy.

Nice review George
I like the Thorfire C8S, it’s a real solid performer
I have 3 in our house (kids a me all have one) and I have gifted another 4 out to non flashaholics and they love them too.
I feel confident in giving these out because of the low voltage protection and can take protected Panasonic NCR18650B’s or the Sanyo 18650GA protected too
I give these out with Liitkala i200’s or 100’s
All up around $30AU a perfect gift set
I find it’s really useful for up to 100-130 metres and can reach about 300 metres but I wouldn’t say it lights up much at that distance but you can definitely see a bit of light hitting that distance
This ain't no party, this ain't no disco,
This ain't no fooling around
I got and modified several of both (Thorfire C8s and Convoy C8). In quality they are comparable but I like driver and and tailcap of Thorfire C8s more.

Thanks for the kind words people !
I’m already modding the C8s , a <5$ mod (not something “new”) that can make it throw waaaay better .

Well, you weren’t the Barry I was referring to in my post
, but I was buying them for $13 to $14 (for the older, upgraded model :D), through Slickdeals a while back. They are actually $17 on Amazon right now, but back-ordered. I’m going to order 1, and a TS07 I’ve had in my cart for a while.

Nice review. Got one several months ago. The cutout in the tail cap is a big improvement in my opinion. It fits the Convoy C8 also. I seem to remember TF had a coupon code for a short period, that brought them down to $14 or so.
Resistor mod , led dedome , installed a DTP board (yes , stock board is non-dtp) , bypassed springs and thicker led wires.
I will write a post with the mod , and step by step amp draw change (before resistor mod , after res mod , after spring bypass , led wires change etc .)

Nice review giorgoskok. I have read a few reviews of this newer model, but since I already had a few older ones, I never got one. Your review pushed me into hitting the Accept button, lol. I’m impressed that you got 4+ amps on the stock driver. Do you measure with a clamp meter?
Brian
Thanks! Yes ,i use the Uni-t 210e .
Just add one resistor and voila

Very nice review, we are waiting for the next one!
Nice review George. Well done.
I just took a look at the driver in my New C8s. This one is completely different from my older models, and appears to be different than yours George.
“C8s driver”:
It’s also 20mm, compared to 17mm, in my last one.
Brian
I have another C8s that i got AFTER the review one , from amazon .
Let me check the driver …

Just checked it and it has the same driver i reviewed .
Interesting …

Are yours 17 or 20mm? My inductor has a lot more windings, also. Still, I get about the same as you. 2.9A with heavy leads on my DMM.
Brian
Mine are 17mm .
It also has the sense resistor on the side , as i described , not on the center .

Yeah, my older model drivers looked like this
From what I can tell, it is the same as yours. I stacked 2 r100’s on top of 1 of them to halve the resistance. It was a nice improvement, but I don’t remember exactly the increase. I don’t have a clamp meter so I know I’m not getting that accurate of measurements, anyway.
This was also purchased on Amazon. After they got new stock, at the end of the month. Apparently, they have changed drivers. All modes appear to be the same. Inductor has a lot more winding’s. It will resistor mod the same (although, that resistor looks huge
). Just directly under the inductor. Maybe have to put a strip of Kapton tape there.
Anyway, I love the new tailcap
Brian
