Thorfire C8s Review(one of the HQ C8 lights)900Lm Max output + New pictures of the pill(Removable)
Hello

Thorfire C8s is another look at the,maybe most popular 18650 flashlight,Ultrafire C8.
The form factor is almost untouched.The difference is mostly in the quality of machining and anodizing.
Build quality and anodizing are on top level.I have nothing to point as a bad point,so far.
All parts fit perfectly,without any gap.All edges are precisely machined for a rounded,smooth shape.
Aluminum is sufficient thickness-no skimp here.
I am a fan of the C8 form.Single 18650,big reflector.The wide part of the tailcap provides excellent grip,eliminating the need of additional grip ring.There is also quite good anti-roll shape.

Comparing with two cheap UF C8.
The matte finish of the C8s looks dark grey,compared to the glossy black finish of the UF flashlights.A sort of a "stealth" finish.No any reflection,at all.
The C8s has a one more cooling fin,compared to its cheap brothers.I have only these cheap UF C8. Don't own Convoy,or other high quality C8,to compare.


Thorfire C8s with Cree XM-L2 LED.(left side)
UF C8 with XP-G2 de-domed and XM-L dedomed(center and right side).

Almost the same size reflectors.

Nice cardboard packaging.
Two spare O-rings,Lanyard,User manual,Warranty card. No holster for this model.
A closer look at the knurling and the finish.

I love the matte finish.Nice feel in hand.It makes this C8s to stand out. Nice rugged feel,similar to a smooth stone for polishing.I am not very familiar with the process of anodizing,but imo the exterior is pretreated,before anodizing. The interior is smooth,not rugged(threads too).
One downside-collects dust very easily.
Smooth aluminum reflector. Clean glass lens. No AR coating.Perfectly centered LED.

Some of the silicone over the edges is missing,but the dome is untouched.The beam profile is not affected.


AR coating test.No AR.

My C8s came with a reverse clicky switch(by mistake). Usually the switch should be forward clicky.
I am happy though. Just selecting modes in a single forward cliky switch flashlight is not my favorite.I see no much benefits of using it instead of reverse clicky.
The switch sits deeper in the tail(compared to the regular C8),because the tail is designed for a forward clicky,which is longer.

Access to the switch is harder than usual,but not a deal breaker.

Stable tail-standing.
The front end is also precisely machined and anodized.
All parts fit perfectly tight,without any gap.
There is a water sealing O-ring.

Long protected batteries fit without problem.

Made of metal retaining ring.

Square cut threads at both ends.The battery tube is also precisely machined.

The aluminum reflector.





Aluminum LED board. There is a white thermal grease applied. I did not removed the star yet,to see how well though.

The driver retaining ring is also made of metal and thankfully it can be unscrewed with pliers/tweezers.



User interface
Four modes:
High-Mid-Low-Moonlight (in this sequence)
Full click for On/Off.
Switching between modes on my sample(with reverse clicky) is possible,by tapping the switch,while the light is On. Sometimes I have to tap it twice to make it work. There is mode memory,which memorizes the mode,if used for at least 3 seconds.
Current draw:
I high=2,15 A
I mid=770 mA
I low= 37 mA
I moonlight= 1mA
Max output(lumens):
High 890 Lm (30 sec after activating)
Mid 380 Lm
Low 32 Lm
Moonlight-Very low,hard to measure it correctly
Peak beam intensity 35kcd.
Typical curve for a buck driver powered by single 18650 battery. No output step down.
The output is stable,as long as the battery can keep its voltage.

The brightness of the C8s's modes is result of a PWM controlling. 
I was very surprised to not hear any high frequency sound of the driver on any of the modes!!
Great work this time,in contrast with my VG10 sample.
The PWM frequency is quite high.Very hard to detect it by eye.
PWM frequencies.
High mode No PWM
Mid mode ~3,9 KHz
Low mode 7,8 KHz(with the lower amplitude waves,I guess)
Moonlight 14,8 KHz
The Thorfire C8s features also Low voltage warning. The light will flicker frequently,when the voltage is too low.     I measured 3,3V no load,after the runtime test.
I like to have this feature,so I don't drain the battery too much,when I can't measure it.
Beamshots
I don't have any critique about the beam. Clean cool white light. Well focused hotspot.
Not too many artifacts. Much better beam than the flashlights with smaller reflectors,I tested lately.
No darker zones in the center.
1 meter, 1/20sec




1/6sec 5 meters


1/6sec 5 meters
Thorfire C8s 35kcd, Olight M22 24kcd, Nitecore EC4 30kcd



1/50sec 5 meters

5 meters
1/50sec
I have only positive impressions of the Thorfire C8s,so far.
High build quality-comparable with any of the top branded flashlights.
Unusual finish-makes it a great addition to any collection;feels great in hand.
The UI is quite good. No flashing modes. The Moonlight mode is really low brightness. Very hard to detect PWM without hunting for it. No any high frequency noise-not from the driver,nor from the switch.My C8s sample is absolutely quiet.(I can't guarantee,it will be the same with all other C8s).
I have not measured the efficiency of the driver,but I like that it's not just a 7135 linear driver. 900 lumen initial output with 2,15A current draw,from the battery.Good runtime curve,without timed step down.Low voltage warning.
Nice clean beam.Much better than many of the higher priced flashlights.
Thanks for reading!
Thanks to Thorfire for providing their C8s for test and review!

Now to decide if I want the 4 mode or the 3 mode. The high to low mode really bothers me, but having a moonlight is pretty nice… hmm

I have the 3+5 mode one, and the modes on the three levels are pretty nice. It is a thrower, so the moonlight would not be that useful to me, just a small ball of glow at whatever I am pointing it towards. The low on the 3+5 modes is useful for walking and not blinding yourself or others with glare. I have to agree, the quality on either is good it seems.

Hmm, I don’t know man but they looks different to me in both FlashLion and James3 review thread,

From James3,

From FlashLion,

Don’t they look different? Or is it just the camera angle?

Looks like an integrated shelf.  Yell 

The old version and new version hosts look suspiciously like the Convoy C8 V2 and V3.  It looks like the Thorfire might be a rebadged line, so it makes sense that they would also be going to an integrated shelf.

Great review Flash! Sorry I did not see it sooner.

I like my Convoy stuff and I think Simon is a stand up guy BUT........

This Thorfire line is something to look at. It is unfortunate that they chose a ***fire name but in the spirit of Thor it looks like they are dropping a hammer on that.. Personally I like the forethought of Forward Switches as I use them often and although I never would have thought about it when I originally bought Simon's C8...the removable pill will make some mods much easier.

The Thorfire stuff is looking pretty good.


It's the simple things that we take for granted that cost us the most

Thanks for the nice review! Great work again.

And there's the driver again that was developed for/first appeared in the BLF X6.

Thanks bugsy36 and djozz!

I love the machining on this flashlight. Absolutely perfect. It is much better than many of the expensive brands.

After reassembling the tailcap and the pill,I can here a high frequency noise on Mid mode Tired Sometimes the reason is switch vibration. Maybe this is what happened after my intervention. The C8s was absolutely quiet before.

I think this torch deserves another bump.

Its great !

A few of us in the UK were lucky enough to receive review samples recently.

That will most likely be from the toroidal inductor. On my recent version it is wrapped in a thick material, very different from the usual shrinkwrap.

If yours is not, you could e.g. coat in silicone RTV.

I bet that would fix it. Don’t use anything rigid, or you risk cracking the core.

Fine review. Really like the Thorfires.

Does anyone know what (specific) LED is in here?

Thanks,

This was my very first real flashlight, after numerous multi-LED AAA junk from various deal sites. I loved it.

Until it was stolen during a house party.

And they keep on. Keeping on.
Better, improved models by the yr.
I had my first C8 yrs ago Ultrafire Q5 Then an Ultrafire XM-L6
Then a Convoy XM-L2.
Currently a SOFURN C8T (Warmer than the C8a model) which is like turning the light on in a dark room. Copared to prev models.
Now I believe they have a 35, 50 ot 70 chip plus drivers in them.

Basically. for 90% of usage. It does ALL you want with decent drivers in there.
I’ve got a cupboard full of torches over last 10 yrs or so.
What do I reach for. Sofurn C8 or my Imalent DN35.
and a Convoy S2+, XP-L (GIVAWAY. Thank’s Southland.) in pocket as spare on walkabout.
With a “BOOM…Daylight”, within range of my old eyes,
Old SKYRAY KING 9 (Updated to XM-L2) pills,
4 cell can light.
Covers whole backyard. 8×4 pool the lot in one hit.
Look out bats.

When you look at it. it really is a (Enjoyable) disease.
Affecting many. costing less than a night in the pub, or a bottle of spirit once a week, with much more enjoyment for much longer time.
My fav torch is still an old (8 or 9yrs)SkyRay S-R5 with XM-L2, driver to match in there now,
was Q8 originally. Drop ins surely help.
Most comfortable torch to hold long term out of all of them.

With a leetle $1.65 Chinese special Delivered (x3)
for bathroom work, Hi\Moon.
Fits perfectly between lips when handling things. Shirt pocket. wife’s bag.

But. We’ll go on forever. Looking. Looking. Wondering.
Maybe the next one hey???.
Human nature is a weird thing when aroused. Thank god.

So the Thorfire has a good spill? I can’t tell from a wall shot. I ask this because I had a couple of lights that looked exactly like this a couple of years ago (or longer) that I liked a lot. Had very good throw and very good spill too making them very useful as an all purpose light. Well I don’t have them anymore (gave one away and one broke) and lately I’ve tried to find this light again. I’ve tried like 3 times in a row buying cheap knockoffs of this light and all 3 had a very small focused spot at distance and next to no spill around you. I hated all 3 as they were not at all a usable light for me. I don’t know what’s happened since I had those I was talking about but the 3 (all no name brands from different places) I bought since then were complete junk and seemed all had way too focused of a reflector in them or cheap LEDs or something cause they were sure not the same. I read this and wondered if this was a comparable light to what I had. I’d be willing to try again if I don’t get the same thing as the last 3. Here is a link to one of the junk ones I bought and the other two were from ebay. My cheap ass tried to save a buck and struck out 3 times in a row.

Sofirn is clearly the winner in those videos, and rightly so. It’s a 1700 lumen beast in a wash of 800 to 1000 lumen C8’s. Convoy may have made the C8 popular but others just improved upon it.

Only one mans opinion folks, and in that opinion Sofirn is putting out phenomenal C8’s for a very small amount of money. C8T, C8A, and C8F. All very worthy of your hard earned dollar.

Mike89 I have this beam shot of a the Sofirn C8A. The shed is about 100 meters away.

Now that screenshot looks pretty good, a better representative picture of total light. Well I took the plunge and ordered the Sofirn from Here

Hope I get a better flashlight this time than the last 3 lights I bought. Thanks for the tip on the Sofirn. I’ll post back when I get it. To show how long it’s been since I ordered anything from Ali Express is now I notice I did not get put through so many hoops as long ago when they required photo ID and a copy of a bank statement just to order something. Now that junk is gone and they take Paypal now. Much easier to order from them now.

I should have read your post before I posted mine. When you said using the light was like turning on a light switch in a dark room. Now that is what I’m talking about, that’s what I want and what was like the others I’ve had years ago and quite unlike the 3 “no name, save a buck” lights I bought trying to find that light again. Turning on that light switch using the 3 junk ones I bought was akin to seeing a small spot on the wall and not much else. Good for searching for spiders but that’s about it. I need to see what else is around besides the spider. The Sofirn I just bought has shipped and I’m looking forward to checking it out.
