If it is still available - from what I read the high-CRI ones were a temporary find - Do you mind sharing the link to how you ordered this ?
Thereâs three options: âcold white 5900Kâ, âcold white 5500Kâ and âwhite 3000Kâ. The high CRI option is cold white 5500K (the LED isnât 5500K btw, but itâs labeled as if it was). I believe that they still have these LEDs, but, just to be safe, i would choose the option âonly lampâ. You will have to reflow them yourself though. If you get them soldered thereâs the possibility of they sending some already soldered LED in a spec different from what you choose. They all look the same, and they can accidentally mix things up. Sending messages requesting this specific version can also lead to confusion, so i would avoid that too. Remember, the LED isnât 5500K, so if you ask for the 6500K high CRI version they will send you the closest thing available, which is the 5900K NOT HIGH CRI option, and the worker in charge might not know what CRI is about, so, more confusion (they surely have specialists in their team that know what CRI means, but they arenât the ones responsible for cutting the reel tape or reflowing the LEDs or sorting the packages).

Thank you! I will do just that and hope for the best. Your beamshots look too good to be true.
For another build with a larger L70, would you still go with the 7060 W45VCA1 over the Yingding 7070?
Edit: for the build with the L70 I am hoping to get similar throw to a SFT40, but more lumen overall.
For maximum output i would use the larger die 7060 LED. I didnât made peak output comparisons between them but at lower currents the 7060 performed way better than the 7070. Intensity of the big die 7060 was similar to the glass 5050 low CRI. Only thing on the 7070 that is imo better than the 7060 is tint, but that wonât matter on a build like this. 7060 tint is similar to the 6500K SFT40, so itâs not bad either.

Thank you! Sounds perfect for my intentions.
How hard would you recommend driving it? Is a 8A buck driver enough to out-throw an SFT40, or would it be better driven by a 12A linear, or even more?
I donât know for sure but Iâm running 12A on the 7070 using a shunt modified convoy linear driver and it seems like it can take more than that. The 7060 die seems to be slightly smaller than the 7070 die so 12A should be enough. The product description says 13A for the big die and 7A for the small die 7060 (the big die have twice the surface area of the small die). The 5050 peaks at around 1800 lumens, so we are talking about 3600 lumens of theoretical peak output for the big die (SFT40 peaks at 2600 lumens).

I had some spare parts laying arond so today I have modified Convoy S8 with Covex lens and SFT-12 driven at some 3.5A (donât remember from where I salvaged the driver).
Soldered MCPCB to the pill to make it sit firmly
And resin glued the lens
Adjusted the pill depth to get the most focused beam
And as a result I got ultra focused narrow beam in a small flashlight without any spill which I like more than expectedâŚ
Sorry for the hopeless picture (I hate Samsung phone cameras). Trees at 45m. The beam is similar (in range and brightness) to NM1 with SMO but totally without any spill and round in shape⌠I really like it

Does it turn blue due to high current?
1 Thank
No. And due to quite stable color temperature across the modes I would even dare to push it harder.
Edit : will do more pictures at my evening walk with Huawei P30 phone so the pictures should be better.
1 Thank
Since I donât test the SFT-12 yet it is all at your own risk I would say 
1 Thank
Yes Iâm totally aware of that but my curiosity takes it over. I got a few more so no worries in case of fatal overcurrent.
That looks like an upgrade over the SST-12. The ones i tested were crapping themselves at these currents.

Swapped an old Streamlight Protac 2L-X from the original XP-L to an Osram W2.
Much nicer beam and a good bit more throw, even if underdriven, and not perfectly centered.
Was incredibly easy to swap, the bezel wasnât glued and the pcb retainer came off easily.
Pics coming later.
Apologies for the blurry photo, Iâll try to take another in the future, as well as beam data. This light belongs to a family member so I was in a hurry to get it done and given back.
20.8kcd of intensity, beam has some tint shift because of the blue AR coating on the glass.

Upgraded a Mateminco FW3 from the stock forward clicky to a Convoy 16mm reverse clicky. Drop in replacement with the Covoy swith boot, might need a spacer if youâre reusing the stock one. But personally I prefer a brighter switch.
Reusing the stock translucent ring instead of the clear Convoy one might also lower the brightness a bit.
Stock switch:
Convoy switch:
Makes the light so much nicer to use.

This morning I was operating on Q8 PRO.
Swapped 20AWG leads to 18AWG
Replaced XHP50.2 with SFT-40
Put things back together
And compared beam pattern to original (left).
And no doubt this improved beam quality and focus/throw significantly. No (or tiny little) tint shift, much better defined Hotspot and maybe some lumens drop but thatâs fine for me.
Hope to provide nightshots after evening walk.
Have a nice Sunday guys

Today I put together an SFT40 3000k D4Sv2 for a customer as well, the beam is the same as my 5000k D4Sv2 though it is nowhere near as intense. Using convoy-sourced emitters, the DUV was -0.0005 and a CRI of 96.7
Iâm looking forward to seeing how the FFL505A perform, should be a lot more rosy and noticeably more intense.
I also swapped my TS10v2 to dedomed 519a 5700k, because the original emitters were burned and I got a refund. Was my first time putting together an aux PCB, surprisingly tricky to hand solder.
Used an MCPCB and aux board from Master_Nate (on Reddit), worked well though needed a lot of sanding of the edges to remove the manufacturing leftovers.
The tint is incredible, 219b-levels of rosy, though the beam is not as good as the originals, possibly of my own fault for not getting the emitters perfectly seated.
Also, did some more modding today and in the last few days.
Roughly 2 weeks ago, I swapped 4000k XHP70.3HI into my Haikelite MT09R to replace the incredibly high-CCT XHP70.2. Sorry not many pics of the operation, I was busy working on the light. @Texas_Ace you might enjoy this one
Incredibly high intensity, with Samsung 20S and dual-FETs it has 252.8kcd of intensity, though it is R70. Surprisingly neutral tint, doesnât get too rosy or green, right at a DUV of -0.0003
Few days ago I finally got around to fixing my Pioneman K75 (equivalent to a Convoy 3x21C with SFN43), the replacement driver for it wasnât working so I decided to piggyback it with a spare D4v2 driver that I had. Itâs a miracle all those wires were able to fit.
I also ârestoredâ a Mateminco MT07 I bought used, fully disassembled it, washed it with soap and water and a brush, repasted it and updated it from Anduril1.
A previous owner swapped a mix of partially dedomed 519a (2700k outer, 5700k inner) into it, which gives it a gorgeous beam at 2650k and -0.0045 DUV. Surprisingly tricky to reassemble, compared to the Hanklights Iâm used to, because of how short the emitter leads were.

Itâs a shame Sofirn doesnât make a smooth reflector for it, like they did with the BLF Q8, though they might be interchangeable.
