I like this light a lot also, kind of like a mini-BLF-Q8. Your ceiling bounce estimates are similar to mine, and I agree that the mode spacing could be better, but it is what it is.

I’ve found the quickest way to get back to low is to just turn it off and then back on again (with a quick-press to avoid the memorized level).

The new code is Q9ZWHJVR. And we also provide some codes in this thread.

DB Custom, would one of these work for the C8F? https://www.digikey.com/products/en?keywords=Vishay%20SIR404DP

I use the 404 most of the time now, so I’d say yes. Wink

It’s interesting how certain FETs can limit output. I wonder if TA drivers can be swapped with a “lesser” FET in order to reduce max power on a small light which can’t handle big power in the first place?

Why put a FET driver in such light in the first place?

The awesome UI of course.

The supfire in my sig has a TA driver with 2 × 26350 cells. It does over 7A, but I’d like to limit it to 5A or so. The extra amperage doesn’t do much except add heat and reduce run time. This is an everyday work light for me.

It would also be helpful for fet drivers using the xhp50.2 as they tend to burn up due to too much current.

I've said this before somewhere… how about setting an inductor in series with the emitters? This can reduce emitter current to some extent, while at the same time filters and increases efficiency for PWM modes.

Teacher, this Sofirn C8 is what Convoy shouldv’e done years ago, after all the triples I’ve built using the Ledil CUTE-3 optics this reflectored version really rocks! The side switch really steps it up as well, you DO know they’re offering hosts for like $14, right?

I was impressed with your review of it Dale… that is what sold me on it. You seemed very impressed with it.

Nope… I had no idea about the hosts. Facepalm I did not see any on Amazon. Did I just miss them or are they offered elsewhere??

My C8F arrived today from Amazon. This is certainly an impressive light too. As was stressed in the review…. Sofirn did this right!!

Thanks again for the review Dale!! Smile

Oh yeah…. hosts ordered too, be a while before they arrive though. Wink

I built up a host with 3 different colored XP-L’s, I think 1A, 3D, and 5C, and the output is fantastic! About 3800 lumens from a FET driver with TK’s ramping firmware and ramping UI. Not the simplest of builds, what with the side switch and it’s wires to get in the way, probably the MCPCB screwed to the reflector and then the reflector screwed into the head make an impact on the ease of build as well, but all in all it’s worth the effort, the supplied e-switch is on a pcb with lights already installed so if a lighted switch is one’s thing then that too should be pretty easy.

Wow… that sounds pretty neat. I’m looking forward to getting my hosts, giving it a go, and see what happens… Wink

Don’t know. Have you tried any of the listed codes to see if any of them work??

You mean because they’re kinda “rough” looking?

I wouldn’t let that bother ya… you shouldn’t be lookin in there anyhow Silly

You need to just buy it, this light is EPIC!

Amen to that….. Thumbs Up

First time you fire it up you’ll forget “those lines” completely & never give them a second thought. Wink

Why didn’t they use XP-L2 in this light as with the C8A?
I hope they will in the future for extra output.

After the initial fiasco with the first version of this light (without direct thermal path board LoL) they probably decided to play it safe with these higher Vf XP-L emitters, which have a nice tint btw.

Just curious, can you elaborate about the “initial fiasco” without direct thermal path? Sorry I hadn’t read about it. So did the LEDs overheated and burned up without it?
