[BLF Group Buy Interest List] Sofirn SP33S High CRI Edition: the GT-FC60 R9080 saga! (26800 tube/extension is a possibility now)

Hello again BLF.

This time, I have something a bit more… interesting to discuss about you.

Remember the thread about the nice new Getian LEDs I found and got some samples of?
https://budgetlightforum.com/node/81315

Well, some of you probably already saw that coming from a mile away because of another thread, but here it goes:

I decided to discuss an interesting business proposition with Sofirn as a first step, and that was to use the glorious Getian GT-FC60 High CRI with good tint binning in place of the current XHP70.2 in the Sofirn SP33S!

with this large nice LED waffle

All of this would make the Sofirn SP33S BLF Special Edition: High CRI!

This would be the exact same light, except for the change to a High CRI Getian FC-60, which entails:

- Higher throw per lumen
- Much better tint and practically non-existent tint shift vs the current XHP70.2 model
- Much better color rendition
- Waffle style LED Big Smile

LED specs that were asked for the final production version of this special light:

  • 4000-4500k CCT
  • Ra9080, which means 90CRI minimum, 80 R9 minimum, and all around excellent color rendition
  • Good tint binning with a specified duv range of -0.005 to 0.000 : this one is especially important, and one thing that I will make sure gets into the production batch no matter what.

As noted in the title above, this is mainly an interest list to signal your interest to Sofirn that it would be a good call to make such a version of the SP33S, so please write your interest below if such a light intrigues you! This is especially important since it allows Sofirn to gauge demand.

Note: I will do everything in my power to get the best GT-FC60 possible so that we may get a beast of light in all regards Big Smile

Sample testing on Sofirn’s part is currently under way Big Smile

An Excel spreadsheet will soon be added to make it much easier to track interest.

Update 1:

I’ve asked for a 26800 tube, and it seems like we’ll be getting a 26800 extension.
I’ve also asked for a green AR coated lens so we get more rosiness over more green.

Update 2:

Some pictures!

I wonder if Sofirn could be convinced to make the BLF version 26800 compatible… it’s just a longer tube, right?

Definitely interested! Personal preference being as close to 4000k as possible.

Sort of interested.

Would prefer the GT-FC60 in the Convoy M3-C as it regulates at a constant brightness instead of Sofirn’s rollercoaster heat management, but I think I could be convinced.
Is there an estimate of max and sustained brightness in the SP33S?

Interested in this LED for sure… Hopefully soon, more details about the light will be out since Sofirn is on the move…

If we could get the firmware/controller chip swapped out for an Anduril one we would have much better thermal management, it would be nice if that could be done too.

Interested but not 100% convinced, probably intrigued enough to gamble on it though.

I’m interested as well if this can happen.

Seems very interesting but I would have liked an host that uses 21700. I know I can use a 21700 with a sleeve but it’s still too big for EDC’ing.

You’ve all been added.

Now let’s address some concerns:

- Why not Anduril 2 for this light?

Well for one, Anduril is a nice UI, but even in its simple mode, it can be daunting to use.
Practicality wise, this would require a driver redesign, and we mainly wanted it to be a direct LED swap for now as to make it as simple as just swapping the LED Smile

This was done specifically as ground zero for this new LED, and making it an inexpensive investment in a light that is already quite good overall.
If the light is very popular with the LED, I might consider asking Sofirn to put Anduril 2 on the light.

- Why not a 21700 light instead of 26650?

Believe me, I’d have preferred a 21700 light myself, but since the other light with a capable boost driver uses a 5050 LED, that makes the swap to a 7070 LED a bit more difficult.

Now, the Sofirn C8L is the next candidate for such a swap, but that’ll come later since it would need a reflector swap Smile

I was actually thinking of this host to put the FC60 sample in, and making a QFN16-T1616 to TSSOP14-PIC16F1856 adapter to convert the driver to anduril, might be possible but it depends on the layout of the ot MCU. Indeed it would be nice if Sofirn could made an Anduril edition, especially since the thermal regulation appears to be wonky on this model.
Edit :

(Picture courtesy of Haukkeli)

There shouldn’t be many changes needed for Sofirn to make it anduril compatible (T1616), lots of space for a different trace layout on the daughter board, then it would just need an additional connection to the main board for the programing pad.
