[Canceled] Sofirn SP70 BLF Edition

Does anyone know if I can use a Sofirn SP70 driver in the original Convoy L6? I read the L6’s XHP70 is 6V, is the SP70 6V or 12V?

I do not know what diameter of the Convoy L6 driver. The diameter of the SP70 driver is 30mm but it has two bumps. You may need to grind them. The LED on the SP70 XHP70.2 is 6v.

If it fits, you could. It would at least be close on size.

I wouldn’t, though. The UI isn’t great and the FET is sub-par. You’ll also want to replace and/or bypass the spring if it comes with one.
Grab something from Lexel instead if you can.

Edit: Saw you said original L6, so XHP70. Nevermind the comments about springs/FET.

My L6 uses a 30mm driver. It’s 6v as it’s 2 cells in series. No boost drivers here. It should fit once you file off the 2 ears. The UI is fine for me in ramping mode. I don’t see a need to mod the double spring. The stock FET should keep you from burning up your led, so I would not bother changing it. The only thing I miss on the SP70 is the voltage readout that NarsilM has.

Appreciate the quick response.

Had a customer fry the original driver by inserting the batteries backwards. I thought the driver protected against this?

Have a couple SP70 drivers on hand so I’ll use one. Wish the notches in the side switch existed on the L6 to easily change drivers

A quick google search shows the FX-30 driver does have reverse polarity protection. Maybe his diode burnt up? IDK. I’ve never done that.

There a a lot of L6 threads, people usually file notches in it to be able to get it out easily.

I did it as well, but doing it symmetrical you have more material to file

I have a newer model Convoy L6 70.2 that I got in January. It has the notches already so it is easy to remove the side switch. The twin Wainlight I got in March did not though.

Also I have an SP70 driver, it does fit the convoy but the wires to the side switch are too short for use in the L6/clones, so you will need to replace them with longer wires if you chose to go that route. Since you have the SP70 driver you know it has 4 cables to the side switch. Mine were all black so you need to keep track of what positions the new wires need to be. I know it fits, cause I tried it before getting a Lexel driver.

Its not a bad driver for basic ramping mode and memory (similar to C8F triple 21700), plus double click for turbo. The side switch PCB isn’t round like the Convoys, more like octagon shape, and tiny bit smaller so should fit through even without the notch. Mine was in the Convoy so already had the notch.

I have the Wainlight cousin as well (Brown), but that one has a Lexel driver with Anduril and lit side button (blue LED), with bypassed springs running around 6800lm start up (Texas Ace Lumen Tube). I haven’t changed the LED wires to 18ga yet. I think that will help bring it up past 7000lm. Using Golisi S43 gold cells.



Thank you

I’ve already switched it over to the Sofirn Sp70 driver and it’s getting 3600 lumens instead of the previous 2850 so that’s nice. I ended up just re soldering the wires as it was less hassle than filing in notches.

The Sofirn TK70 gets 7200 lumens with bypassed springs using button top PLB 26650’s, the same ones Sofirn sells but my supplier added a button for me.

The L6 had some great potential. That’s the issue I have with Convoy is Simon isn’t into using drivers/firmware of the competition e.g., Anduril & NarsilM.

Why the low 3600? It should be higher than that.

Cool - Yeah didn’t see this until now. Didn’t know if you had already done it. Glad it worked out. With the XHP 70.2 it should provide more output.

I have no idea what the bin is for the Convoy vs Wainlight, both are 5000K temp. My Convoy is now back to stock driver with sense resistor mod, and lit side switch running just a tad over 4500lm on Texas Ace lumen tube at start up. Pretty satisfied with that. Especially with stock LED wires, and spring bypass.

This is the XHP70 in NW, not the XHP70.2.

It could be the dual high resistance springs on the Sofirn driver if it’s low

I think his was using the XHP 70 not the newer XHP 70.2 so output is a bit lower. Even with resistor mod it would go up only to about 3800lumen based on Vestureofblood’s posted output.

Not too familiar with the XHP 70 output vs 70.2 but could be the reason.

Okay, that makes sense. My CW xhp70 seems to max out at around 12 amps and the NW is usually a lower bin than CW. I thought you had a 70.2 in there.

Soooooo, what ever happened with this? Did we all just forget about it, decide we don’t want it, or did things fall through?

Welcome to BLF on your first post!

Lux-Perpetua is running this with his contacts at Sofirn, and he was out for a while, recently returned. Hoping these posts will illicit a response. The driver part is easy if we go with a FET and 7135 design. Basically the driver is already there because a driver designed for the L6 exists, and can run Anduril/Anduril2.

Most of the other things are tweaks/improvements to the light, such as SMO reflector, improvements in design, SS bezel, etc. What makes this light special is the big reflector and dual cells. It's an excellent host for high amps and max throw out of an XHP70.2. Most of the changes shouldn't add much to cost, accept for maybe the SS bezel.

It's also been made clear by Funtastic (and I've seen it on mine) that the SP70's have a poor machined shelf the MCPCB sits on -- this is a QC/production problem that needs to be addressed in this version as well.

I’m surprised people want an SMO reflector. I tested one and preferred the stock lightly OP version. The beam looked better and distance was very similar.

I haven’t looked at the shelf. Is it a bit rough?

I agree - this OP seems to work very well. In the past though if you recall, SMO was a big thing for big XHP70.2 throwers - I got a couple already, think the L6 and MT07. Here is one thread on it: https://budgetlightforum.com/t/-/42286. VOB compared throw #'s, etc.

Well on mine, there's a small bump in the middle, but Funtastic bought about 10 over a period of months took a vid and posted about the lack of flatness. Not sure in which way - at least the middle bump and burrs around holes, just not sure of the flatness of the surface itself.

Every light I break down and/or mod, I check the drilled holes for burrs and the shelf for flatness, so I'm quite used to detecting and fixing them.

+1 for BLF Edition.

I know some think it’s not necessary in such a light, but I would love to see a high(er) CRI option.

I will get in touch with Barry asap. Driverwise, I was always hoping for something like Convoy‘s FX-31 2S/3S buckdriver that should physically fit into SP70 and that would offer more stable output. Sofirn has successfully launched their new SP35 flashlight with constant current regulation, so maybe there’s some room left for even more potential in SP70 BLF edition.

I wonder if Sofirn was interested in the GT FC40 12V LED that Simon is now testing in the L6. Can it be run with 6V or would it require to use a boostdriver?
