It might be a shady move from Fireflies. It might also be that they accepted one of the lowest bids and didn’t realize they were buying fakes. In any case, Neal refunded me $6 because he said the fake should be worth about $5. So in the end, I paid $5 for a $5 battery. I’m not upset.
Did you receive a fake that you can test and compare?
Ahhh, was just gonna say, no, can't fool me 
, but wait... Ok - did buy a pair 
. Just went thru my 21700 inventory and I got 13 cells - 2 Sofirns, 2 Shockli's, 1 Vapcell 1 30T, 2 40T's, 2 iJoys (1st ones I bought). 1 LK, 1 Molicel, 1 50E.
Hhmm, all for just 4 21700 lights, but I can fit them in to a couple 26650 lights.
What’s interesting is that a lot of people are claiming they are Lishen batteries, but all the Lishen 21700 cells I’ve seen are rated for around 12 amps and these fake 40Ts seem to be putting out much more. I know they aren’t Samsung, but I’m curious what they actually are, and how the Fireflies cells perform in instrumented testing.
LORD NO! It would not recognize what I’m saying like my phone LOL. I think Bluetooth or usb/micro connection computer/phone app. 
He did the same for me.
Ooops, got Sofirn confused with FireFlies - no, no cells bought from FireFlies.
Continuous discharge is not the same as what they can do when pulsing @ 0s. They will get hotter and wear out sooner too running them like a 40T
I've sent two messages to Fireflies about the two fake 40T's which I got but zero response from them so far in the last couple of weeks.
My second E07 came in today, silver version with XPL-HI 4000K emitters this time. I ordered a Samsung 40T too, from Fireflies. I have no genuine Samsung 40T to compare, but the battery that came from Fireflies has no ring on the negative (just a light round scratch probably caused by the spring when screwing the tail cap). It is not crushed either, probably just the right length. Now, just from the font on the writing, it is really hard to tell if it is a genuine Samsung without anything to compare. It says: “INR21700-40T, Samsung SDI, 2IA2”. Can anyone confirm that all confirmed fakes so far had a real ring (not just a scratch) on the negative?
Other than that, I can’t say I’m a big fan of the silver finish. Someone said earlier he/she feels like the light comes from Walmart with this finish, and I kind of agree. I do know the build quality is actually great and the body is very well designed, but there is a bling bling side with it that I don’t really like. I’d be happy to trade it for a grey one if anyone is interested.
[Edit] Looking at the “21700” digits on your fake 40T, it seems that the font is better on mine. Could you please measure the spacing between the right of the text and the negative end of the battery? It seems to differ significantly between both. I can also see some faint codes elsewhere on the wrap: N40T, IA901, C11, EA, C6, W1B. But they are all very hard to see. The battery weighs 68.2080 g (yeah, it’s an accurate balance :o).
If you are quoting me I was saying that I don’t like shiny black lights, and they remind me of Walmart lights. I was saying that in response to posts of people not liking the dull Black and Tan.
Sorry, I misunderstood, I thought you were referring to the silver finish. Then, I am now adding that I don’t like shiny silver as much as I thought I would, because they look like Walmart lights. 
It’s not that bad though, but I would clearly prefer a mate finish, like stainless steel. I think what I dislike really is the shiny aspect too, more than the silver, as I would not like a shiny black either.
I was thinking about trying scotch brite on my tailcap to see if it dulls it. I believe it has a clear coat over it cause it will not polish with metal polish
I guess you guys would like the looks of the Amutorch X9 w/titanium tube, or the Amutorch AX3 head then - it's a dull/matte finish which to me looks cheap. I prefer the shiny titanium of the D4Ti tube, and shiny polished copper for flashlights. Even the SS bezels on the Amutorchs are a dull matte finish. I think the E07 clear ano version looks great as-is and doesn't look cheap at all, but when I think about it, for bathroom/kitchen fixtures I prefer the matte nickel or SS finishes vs. polished chrome.
What emitters and aux colors does it have?
I think the X9 bezel is titanium .
Well, for what it’s worth, the E07 isn’t polished Aluminum at all but merely anodized with no dye bath direct from the CNC machines. I love it, looks like I made it myself! (Yeah, right!) Does make me wish I had a mill though so I’d have the technical ability to make such as this if not the actual skill set… lol
As far as looking like a WalMart light goes, the only light I ever bought at WalMart is a MagLite and they have legendary ano skills so…. not sure why a WalMart light would have to look cheap by default. Buy dirt cheap, you get what you pay for…
Does the temperature protection only works at turbo mode?The light went dimmer(from turbo to ???) at 55°C.After that, it stays at the same level, so the light went very hot—->70°C
Is that normal?
Have you calibrated the ambient temperature setting in the light and also set the thermal step down? Relying on factory settings is not typically the way to go, they don’t set each and every light to work to your specs out of the box…
Calibrate the temp and set it lower. It works at any level above 380mah i think.
Yes, callibrated it with the temperature of the led board, step down at 55°C (25 clicks)
