Is this still the old version with problems or does it have the updated head?
Guess I will be finding out, as long as it is not glued I am happy. If it is then I will sell it.
Hmm? Not helping. 
LOL, I have no idea. You could try sending the seller a message, although I would not hold my breath that they even know what you are talking about and/or could answer it if they wanted to.
I know it will be a working light or aliexpress will refund me so I figure for that price it is worth the risk. But thats just me.
Yeah, how do we know that BangGood didn’t dump the rest of their stock of dodgy lights upon this poor unsuspecting soul, who is now reselling them on AliExpress? Or it could be BangGood themselves selling via an undercover name.
That’s what I was wondering. I’ll try sending a message
Seller seem to be eager to get rid of that product. Buyers please take note.
Remember that things that sound too good to be true often are…
The listing that oleg007 provided above clearly states the following: “This is the new version with the new head could be opened and without blue light issue.”
I would guess that this would be the new version, not glued, and non-compressing optics…… Just a guess though. :innocent:
Could be legit then, the Nichia version is USD 36:73 though (which is less than the USD 50:- BangGood currently charges, the Colored Nichia version is “only” USD 42:- from BangGood though; it’s a strange world we live in).
It’s strange indeed…
You’d think the aluminum S41 would be cheaper, and even then $26 would be a bargain…
So should i buy another S41S?
If it’s a dud i just open a dispute and get my money back, right?
I already have too many but still want to buy one for $26
It will bring down the average price you paid for them. :partying_face:
I understand the feeling, it’s a damn nice light.
In the Dutch version of the page it clearly states it’s the “new version without the blue light problems”. I ordered one anyway. Don’t believe in this “BG might have dumped …” complot theories. Just send it back if it’s no good. Seller rating is high. I’m optimistic.
$25.70! Now I have a place for those 219Cs 
Ok, ordered the XP-G2 with ePacket delivery($1.58) and -$2.00 coupon.
$27.28 Shipped. Have a spare 18650 tube coming from BG in an earlier order.
This is the best deal I got out of the S41 and S41S collection. Second best is the S41 Nichia for $30 Shipped on Amazon Prime with 2-day shipping.
But I won’t talk about the very first S41 I received and it was defective 2 weeks later. Paid $45 for that one and actually got a Full refund on it. Turned around and bought another for $37ish. Used the $8 to buy 2 Nichia 219C. Learned to reflow emitters and brought the #1 back to life. So $45 Divided by 2 equals… Shhh, quiet, don’t say it.
And the defective head, $8 tube, $9 tail SW assembly, 2X XP-G2 R5 4C @ $1.47ea from Simon. $20
But as far as averages… I have Seven (soon to be 8) and Only 3 survive as they came originally, still functional. 2 of those are the revised S41S versions and one S41 Nichia.
Oh, the Elfeland Outdoor Lighting Store also has the Tail assemblies for $6.50

I just got my S41S (Nichia 219B) from Banggood, a very nice but heavy flashlight, maybe to heavy for EDC.
What I don’t fully understand, why does it get remarkably hotter than the BLF A6 at comparable brightness settings?
Even at level 5 it gets hotter than the BLF A6 at level 6 and it seems not brighter.
Another difference compared to the A6, the UI timing is slower. With the cold flashlight it seems I have to press twice as long to get from moon to turbo (step backward).
Lastly, I’ve seen five flashes in the battery indicator mode with a fresh battery, at least one more than with the original BLF A6.
The Tailcap is very cheap too. But I have bought enough from banggood :cry:

I really want a full alum version for a lightweight EDC.
I believe the heat is due to the lower Vf of multi emitters resulting in higher amp draws. The heatpath of the S41 is also better than the A6.
Brightness levels are very hard to compare when dealing with different beam patterns. It would be tough even with similar beam patterns because our eyes cannot discern small lumen differences.
