Yes, that’s the nice thing.
They are extremely easy to solder to.
That’s one of the main driving points of using these.
Added to the list:
We are at 706 large springs, and 602 small springs.
Have you received the funds I sent you? I’ve never bought from you before and want to be sure you got it, payment message was my username, check the pm.
Yes of course.
I put usernames+private names in an encrypted folder when I receive the payments.
I’m just waiting for the LEDs to ship now, as there have been delays regarding this.
Sucks compared rather than ordering from Mouser, but tint bin trumps everything.
In other news…
Sign me up please for:
1 large + 2 small for my Manker BLF A6 (will those work?)
1 large + 2 small for my Manker BLF X6 (will those work?)
1 large + 1 small for my Lumintop GT Mini (will those work?)
4 large + 4 small for my Lumintop BLF Q8
4 large + 4 small for my Sofirn BLF LT1
8 large + 8 small for my Lumintop BLF GT
Total: 19 large + 21 small 3rd Gen BeCu springs please :D

1. No, not optimally. You want 1x large, and 2x small.
2. Same thing.
3. Only 1x large and 1x small on the tail. No need for a driver spring change since it’s already a BeCu spring.
I did do this mod too. I’ll take a picture of it tomorrow. Fits very nicely. 
4. Yes, it’ll work.
5. Yes, it’ll work
6. Yes, it’ll work quite well.
I STILL DO NOT HAVE THEM.
THIS IS A PIC FROM THE MANUFACTURER.
Thank you BlueSwordM, although I'm not sure about 1, 2 and 3 (A6, X6 and GT Mini).
f.e. the outer springs from the A6 and X6 are smaller (7,5mm) than the one on de GT Mini (11mm).
Also your large (outer) springs are 9mm and don't seem to fit on the contact areas provided, which is 8mm maximum for the A6/X6.
For the GT Mini the contact area is even more different as the outer springs are 11mm and resting on the same measure provided thin contact pad (same for the inner spring), the rest is purple print board, so not like the one full contact pad/circle like on the A6/X6...
Counting only on the soldering to make contact with those provided contact pads doesn't seem perfect to me and kind of misses the purpose of your low resistance springs, or do I mistake?

Can you post some pictures of the mods you've done please?

Edit: I could do a spring bypass on all of them but wanted a more clean sollution for my BLF flashlights collection :D
I’m going to be out of town for a week at the end of this month. I just know it’ll be just my luck that the LEDs will arrive during that week.
I’m a little surprised to see the J5 flux bin (the highest I’ve seen for 4000K SST-20s) in combination with the less green FD2 tint bin. Usually, emitters get greener as the flux bin goes up.
Ooo, they’ve arrived! Thanks for the update. Looking forward to putting them in my FW3A. Any idea what shipping times we can expect to Europe?
I STILL DO NOT HAVE THE EMITTERS.
THESE ARE ONLY PICS FROM THE MANUFACTURERS.
Sorry for partially getting your hopes up.
No worries. That’s what I get for making an assumption :person_facepalming:
Luckily I put some 5D XP-L HIs in for the time being so I’m happy 
You could use a SnPbAg 62/36/2 silver bearing solder for better conductivity.
Thank you 007, to me that seems a good solution and perhaps a good investment to for future soldering pleasures. Thanks for the tip!

It confirms the tint bin, though!
Yep.
The work I did with my dual BeCu springs in my GT Mini tailcap.
Estimated time for the stuff to be ready? I see the leds are on its way or sort of, the springs not yet…
When should O:) I pay? My emitters are all at $1.55 each (3500 & 4000K), doesn't it?
welp missed out on 219Bs (impossible to find now imo) so I’m hoping these sst20s bring me at least within spitting distance
@Barkuti, will send you the payments once I receive the LEDs.
@Sam, I took the picture like you wanted. And they fit fine.
Is there a chance that we will get springs and LEDs by the end of July?
