How is the 219B not dead in an Emisar D1S though?
Its forward voltage is quite a bit lower than even the SST-20, so even someone like Tom E/DB Custom wouldn’t dare put this emitter in a FET light.
That’s an SC64c on the left 
Oh god I was worried 
Also, guys, because of the Chinese Holiday, the manufacturer will not be able to make the springs until February 19th.
However, I’ve prepared all of the LED orders and the envelopes to ship when I receive the springs pretty much instantly after I receive them.
What were the final specs? Did removing a coil make it too small?
Final specs have not been finalized for the large spring yet.
I’ve already tried this for the small spring last time, but did not work theoretically, and the manufacturer advised against doing this too for the small spring.
It should work with a 12mm height, but I’m waiting for a response from the manufacturer.
Do you find the tint green IRL?
@BlueSwordM Any luck sourcing rosy 4000K? I didn’t realise the 3500Ks would be sent out before/separately to the 4000K.
Got my SST-20’s yesterday, Just wanted to give thanks. Very appreciative BlueSwordM. Thank you!!!
Thank you for publishing the list. Could you please reduce the SST20 4000K for me (line 5) to 20 pieces? And please add 20 small NICKEL-plated springs. My flashlights are really looking forward to get some high quality springs! 
Added to the list.
I will be starting to send PMs for payment February 4th, and I will be buying the springs on February 19th.
I will be doing this groupbuy as quickly as possible.
Also, there is a possibility I will be ordering more springs this time if a certain large buyer likes my large sample.
Just mounted/tested my first SST-20, the 3500K, on a 16 mm SinkPad II, in a little decent zoomie - the UltraFire U-F10. The beam tint is looking really nice and rosy. Wow! Compared side by side with my other U-F10 running a XM-L2 U4 1C dedomed, the U4 looks so green. So from stock (XM-L2 ~U2 1A), the lumens is down (320->201) but the throw is up (6 kcd to 10.2 kcd), but now, of course, it has great CRI and a great tint.
BTW, guys, I’ll have to remove the nickel-plated springs section.
I had 500 extra small springs left(200 did not sell, and 300 extra were errounsly sent by the manufacturer)
I do not have them anymore, except for MRsDNF small nickel plated springs.
Perhaps you could share the springs that are left?
The 40 nickel plated springs are literally the only ones left.
What happened to those springs?
1. I shipped 50 to 808Hi.
2. I kept 40 springs for MRsDNF.
3. My Truth Not Excitedly Literally Establishes Connection Truly something Revolutionary Obviously Not Incidentally Confusing, Seriously.
Solve the riddle and you will have your answer.
@contactr, you’ve got it right.
I sold the remaining 410 small springs to Richard at MTN Electronics
I got my SST-20 3500K and installed them in a quad. The tint is very neutral, I like it a lot. I wouldn’t call it rosey personally, its pretty much just neutral.
I’ll try to get some pictures later if I get some time.
Got some pictures of colors. The tint is warmer than this, the camera had WB set to auto.
