Hi Jouna, thanks for these pictures. C8S host in my wishlist, both 20mm driver and MCPCB very nice. May do some fully regulated DIY torch with one in the future.
I'm waiting for a C8T to be reviewed, hope I can at least get some meaningful measurements for that new dual MOSFET driver.
With regards to the photographs, I'd improve focus and increase exposure. If you're using an Android smartphone I recommend Open Camera (F-Droid, G00gl€ Play), most stock smartphone camera applications are a joke.
Yes, I know photos suck. This was my first “real” review so I try to do better next time I did take photos with my old Panasonic DMC-LZ5 camera even better systems camera was few meters away Of C8S: That needs little bit centering with H1-A driver but that’s not so bad
And thank you all!
For the photos, they’re too dark to see anything meaningful- just use one of your other flashlights to provide some better illumination during the shots.
That photo is clearly from my album in cloud. I don’t know if you are kidding or not but photo is for showing what is “integrated head”. There is same kind of photo with more light in my “quick review”.
The Thorfire C8 has not had a removable pill for a long time. An integral shelf. Screwed down MCPCB. And a “fully regulated” buck driver, generating about 900 lumens in standard form. (moddable) Nice simple UI, with useful ultra-low. Also compatible with 2S cells, 18350 or CR123 for example. A personal favourite. Still worth considering.
Not bought one in a while, just reporting my most recent experience, this year.
Interesting information Tom Tom. What you say sounds like a sort of LD-29 driver, also one of my favourites like all sorts of fully regulated drivers. Modified a pair of TA13 torches with H2-C drivers recently.
Take a look, usually on Amazon fulfilled at a decent price. Sometimes in a package with a (good) cell, charger and a bike mount. Their grey anodising is soft, but I like the way they wear with use.
Disclosure: I received one of the first (with pill) for review here, and liked it so much I bought several more. The emitters are on Al MCPCBs, cool white but OK, and the larger XM rather than eg. XP footprint and appropriate SMO reflector, so not perhaps the ultimate throwers. The driver seems very good and balanced to me, but maybe does not appeal to those obsessed with max. amps. I like it, and it seems very efficient to me (run time).
Not sure what you mean by driver boot. If depth of cavity, well I only have my review sample with separate pill, so not relevant to current production. There was enough room left that I considered packing it with a piece of thermally conductive silicone, but didn’t.
Mine takes I think a 17mm driver (screwed into the pill with a nice ring), and a 20mm MCPCB. But don’t quote me on that. The driver is mostly obscured by a big wound inductor on a hefty toroid core, taking up pretty much the full diameter of the cavity. Not the sort of square sealed component I’m used to seeing these days.
But everything may have changed since then, you will just have to take a chance and see for yourself. I don’t think you will be disappointed.
Nice inductor, not so nice current sensing resistor. 82mΩ is too big, causing a lot of voltage drop and power loss in the driver. If current for high mode is 2.8A, Pshunt = I² × R = 7.84A² × 0.082Ω = 642.88mW. Looks like sense voltage is set at ≈0.23V.
An LD-29 uses a 25mΩ shunt for the same 2.8A maximum driving current.This is much nicer: PLD-29shunt = I² × R = 7.84A² × 0.025Ω = 196mW. Sense voltage is 0.07V. How good would it fit I don't know.
I should be getting the ’F by next week, acto the email notifications from the Post Orifice.
I doubt it’d have the throw of a single big-reflector C8, but the idea of trip XP-Gs is intriguing! Wonder if it’d be floody or throwy. Best of both worlds, or worst?
Never had a multi-reflector light, so this should definitely be interesting!
My Sofirn C8F arrived today, what picture do you like to see?
I will try to post pictures tomorrow but I can’t do a full review like everyone here :person_facepalming: .
These are pictures of Sofirn C8F with stainless steel bezel for Convoy C8
