I kind of doubt that you will see 219C options in these anytime soon but I could be wrong. Far as I know Astrolux doesn’t have any lights using the 219C right now and it would not make a lot of sense to get them just for this light.
I just checked Mankers site and in the Manker E14 version it is now available with 219C LEDs.
Last I heard Manker and Astrolux are not friends, like at all lol. Still it is possible they will offer them with 219C’s I suppose.
I just finished modding my S41S (well except for sanding the body).
Swapped the LED’s to 219C 4000K 90+ CRI, used a Texas Avenger driver with bleeder resistor and 20AWG wires. “Activated” the lighted tailcap with a pair of 22k ohm resistors and 2x white 0805 LED’s added some arctic silver and put it back together.
It is VERY nice, like really really nice!
The optics mix the tint very well and give a very nice beam. The 219C die is much smaller then, well everything on the market today. So it also have a noticeable hot spot now and a ream beam.
This is also the highest current single cell light I have, with a 30Q it is 20A, HE2 it is 22A and a efest 18350 it still pulls 8.6A. Compare that to my mixed tint XP-G3 version that pulls about 4A less (but makes about the same amount of lumens due to being more efficient).
Speaking of lumens it is not bad there either. With the 30Q it is making around 3300 lumens and with the 18350 it is still a bit over 2000 lumens. Although with the 30Q it is completely impractical in turbo, 10 second and it is hot, 30 seconds and it is scald you hot. Luckily the TA driver has a regulated mid range mode that works well.
The white lighted tailcap also looks quite nice, I considered building one of PD’s tailcaps for it but just didn’t want to take the time, this setup is not as efficient but it works fine.
Overall I am totally happy with the outcome, Just need to sand down that grip
I asked Manker about it and got these details in a mail:
_219C details:
Tint: 4000K
CRI: 90+
Output: 1800 Lumens_
Just got my s41s from that flash sale a few pages back. It is the newest version, no glue on head.
Interestingly, the knurling on the body is flat without the peaks but the tail cap has the peaks and is very aggressive. I may do something similar to vwpieces so that the knurling matches.
The beam is floody with no defined hotspot, unlike my aluminum s41 which has a defined hotspot. I think the optic to LED distance isn’t spaced correctly.
Naughty Mateminco. })
look sexy 
To much inconsistency in these lights to be able to recommend them.
All I know is both of mine work great, both stock and modded. I have a 1st batch S41 and then this latest S41S.
Able to share your feedback?
Sure, i have 2 also
Tailcap and tube with different knurling
One tube fits snug to the copper heatsink, the other sits about a half a mm off (same with the tailcap too)
the revised design the optics are to far away from the LED resulting in a strange beam pattern
Other than that it is consistent lol.
Mateminco is mankerlightchina at Taobao.com :person_facepalming:
The plot thickens :smiling_imp:
Yeah…
Matemankerlux…?
From Elfeland factory a.k.a. UltraFire…?
Who knows, right? :confounded:
They could have request to rename after separation. #awkward
How long until Amazon has a Mateminco store?
I got my S41s in the mail today. Same source as those above. Very nice light, however now that I have one I need to familiarize myself with the documented issues. I can only use it in the bottom two modes or it shuts down at 36 sec and won’t start back up until after a little wait :person_facepalming:
I have the nichia version but the CRI is low and very close to the XM-L2 3D tint… Very far from the A01 Astrolux.
Is XGP2 or XPG3 better as far as brightness / tint go?
