That’s awesome! Djozz tested the SST-70 and got 4000 lumen at 6 Amps. His lumens are a bit high, but the SST-70 matches the XHP50.2 in output up to 6 Amps. But then you get the increased throw and hardly any tint shift from the SST-70. I’m curious to see what the SFT-70 does as well :sunglasses:
Hi Simon, I have two Convoy T2 with Nichia 219C 4000k and I want to buy another two but they are not available with this led. Do you know when they will be available?
Hi, if you are interested in L21A with Osram led, my review is finally done. And my girlfriend translated it to English, hope you like it 
She is better in this translation stuff.
Yes, this was occuring with NCR18650GA batteries between 3.9V to 4.16V.
It will be available in one week.
pls leave me your address via PM ,i will send one new driver to you
Simon, is there a datasheet for the SFT70 LEDs?
I can’t seem to find anything by search.
Does M21A Osram green giving more lumen that white one?
Thanks!
Is there any website that allows me to share PDF files?
The luminous flux of green light and that of white light cannot be compared with each other.
Simon which tint bin did you get for the GT-FC or did you specify a tint bin when you ordered? For example the C3 tint will be much less green than the D3 tint.

I see your pic with the turbine engine, Sweet :+1:
Thx CNC!
This is the only reason why I like flashlights, working in dark and visibility is essential. Rainbow tints give me a headache and give the wrong perception of a hydraulic leak (yellow-green corona looks the same as hydro fluid on a titanium material)
Recently received S21B, and when I shake it I can clearly hear rattling sound, when I shake head only - sound persists. And when I touch glass by finger I can definitely fell glass and reflector moving (and making that sound). I try to screw down bezel - but it’s screwed down to the max, no space left. And for s21b I can’t screw down the pill (because there is no pill). Any ideas what should I do?
Check the o-ring between reflector and lens.
Replacing it with a thicker one would help too.
Hello!
Just a quick question about early versions of the 12-mode bastard biscotti drivers. I had a ∅17mm driver ordered from FastTech on July 9th sitting in a drawer which I just used for a “dormant” build aaand… holy sh1t! The thing seemed to work right at first, but started misbehaving nearly from the start doing all sorts of glitches: incorrectly changing modes or not in any way I could discern, random strobes, and right now it just doesn't powers on. Already dismantled the S2+ flashlight in which it is installed for inspection a couple times, everything else inside is in full working order. Is the software so terribly bugged? 
That’s a review of a specific bin by Rngwn. I hope Simon got the same
