6800, nice! What cell were you using?
Probably a 30T.
30Ts can output massive amounts of power.
Fireflies just removed the option on their website to purchase 30T's with the E07. I ordered mine with a 40T about a month ago. Will be interesting how bright it will be with that battery when it finally arrives.
Did you get your PL47 already? I didn’t 
Never ordered a PL47, just the E07 and the tracking number doesn't show up anywhere so it may be a long wait.
Just ordered the E07, whats the best 21700 to get? The Samsung 40t? 30T? Or use the Adapter with A Sony VTC5A??? Thanks guys.
XP-L HI and SST-20 5000k/6500k: Samsung 30T/40T.
SST-20 95CRI: Samsung 40T/Samsung 50E
Wow…that was quick, thanks i will get one of them.
QSO rewrapped Sony VTC6A. I will test with 30T later.
Please post the 30T results, thanks!
With 30T, it makes 7,570 lumens! Freaking amazing! It is even brighter than the D4S XP-L HI 5D V2 (3,577 lumens), ROT66 XPL-HI 3A V3 (6,940 lumens), Noctigon M43 (4,310 for LH351D 90CRI, 5,172 for XPL-HI 5D v2, 6,000 XP-G2), and Astrolux MF01 (I think it was about 7k for the 219C).
Too bad FF ran out of the XPL-HI 3A V3 and I think 1A V3 is too CW for me.
I’m going to do more testing on each unit once I receive my E07 order from Neal. Strange that I received my order from FF so quickly even though I ordered it two weeks after I placed order from Neal. However FF made some mistakes in my order: one had wrong emitters and one had wrong aux color. Will sort it out with them.
@SKV89, that's a lot of lumens wow. I ordered mine with the 40T and hoping to get close to that. How does the beam look to you compared to the rot66? From Matts video, the rot66 looks like it has much more flood.
How is it outputting more lumens than the ROT66?
That is really strange.
Floodier than the ROT66. Bigger hotspot when comparing same emitters.
I really don’t understand too why it is brighter than the ROT66 with 3x18650 and 2 extra emitters.
That 30T must be some powerhouse!
That is good news for me as I wanted it to be a real flooder. 30T is rated at 35A and 40T at 30A. I wonder just how many amps your E07 is pulling to get those high lumens.....it can't be using close to max amps on the 30T can it?
The 30T is a serious fatboy cell, no doubt! 
HI’s, maybe 21A… 3A per emitter x 7
A single 30T to the 17 emitters in my Ham’r gives 30.3A.
That would mean the 40T should yield the same results lumenwise as the 30T. Now I'm glad I went for the 40T.
