From how it looks I say e-switch.
The mentioned BLF-A6 driver suggests clicky, and they mention clicky too.
Or they adapted the BLF-A6 to e-switch… (driver group buy, I’m in!)
Or ‘BLF-A6 driver’ is wrong
They do claim clicky, and since the BLF A6 driver is clicky only, it makes perfect sense that they used a clicky in this light. I doubt seriously that they’d modify the driver to use e-switch or use a e-switch driver, yet claim to use the BLF A6 driver and clicky switch on the listing.
neal will send samples so we will know before the groupbuy closes 
It’s probably a clicky design working on the Batt+ side. Again I reiterate — not the best way to go for several reasons. Quality components and simple design is the key, and I’ve only seen awful quality in these type of clicky lights and extra hardware - cheap switch, extra thin wire springs or contacts, etc. Think’n they may be having issues with this design - unrestricted FET driver combined with this type of switch is usually not a good combo. Maybe/hopefully it will be safe/ok, but unable to achieve high amps without modding.
I’ll be in for a group buy for both models. Possibly 2 of each
Ok, so it's a true e-switch. Guess they are stumped why the BLF A6 firmware won't work... 
The switch looks exactly like an Eagle Eye X5's e-switch.
Hi,
the samples came in this morning. There is definitely not the BLF A6 driver inside. 4 normal Modes with a huge step from Moon to Low, Doubleklick activates Strobe, Bike Strobe (?) and Beacon. Single Click from off switches the light on to Moon and changes mode. Long press from off activates the last used mode (memory), long press from on switches the light off. I did not find a Config Menu or Battery indicator. The light feels good in the hand, pretty comfortable. I measured via ceiling bounce in comparison to a Skyray King (2000 Lumens) 896 Lumens for the E01 and 904 Lumens for the E02.
I contacted Neal for further info on the used driver. I guess it is a 3A driver.

Thanks !
What about battery fit? Do protected batteries fit length and width wise ?
Can you get the driver out? Does the bezel unscrew? Appears to be threaded — really, really hope it’s not glued. I don’t see a retaining ring on the driver, which doesn’t look good to me - might be glued in like an SRK. That DL044 on the driver sounds familiar, hhhmmm…. Can’t recall where I saw it.
Ohh - can you take body length measurements? It’s been a mystery - they never posted dimensions. Based on the size of the clips, it looks fairly short, which is good.
That’s not the advertised driver at all !
And that step from Moon to Low was to be expected but will be annoying for sure…I’m not in anymore :-x
And the dimension?
Thanks for the info sofar. Of course I would like to know some modding details: can the emitter be reached, is the driver 17mm?
Kenjii - no rush, we can wait. Well, maybe a couple of nanoseconds... 
Thanks for the info so far! BG is really disappointing on providing correct or useful info on these.
Looks like the driver and switch are on a T-shaped board
Hi,
i was swimming with my kids…. info coming soon. One protected battery is left, all others are unprotected

Hi,
ok, here we go.
The battery tube is 19mm diameter. A protected Sanyo 18650 (69mm, 18,5mm) fits but is at the limit. I don´t have any protected 18350. The battery tube with tailcap of the E02 has a length of 75,42mm and the E01 43,84mm. So in theory 18350 up to 37,42mm should fit.
The driver is 21,3mm diameter. I think drivers up to 22mm could fit. The driver is not glued because you can move it a little bit. But it seems stuck somewhere, possibly somewhere at the switch. I don´t want to press it out and disassemble the whole light before doing the review about the lights
Edit: Overall length is 105,4mm for the E02 and 74,3mm for the E01.
The LED is not glued and not screwed. Just press fit with a good amount of thermal paste. The Bezel is not glued and the reflector threaded into the head.
Regards
Kenjii
Thanks
Thanks, but how did you get to the LED to see the thermal paste? What is the overall lengths of the two lights?
Edit: - ahh, ok, so the total length of the E02 is bout the same as a SWM C20C (105 mm), which is a good compact size for an 18650 EDC light. $30 is a little steep for these lights, depending on the finish, specially since I'm only interested in them as a host anyway. The Group Buy price is decent enough. Still I have to learn more though - need to know the driver and e-switch setup, and how they can be upgraded to a custom OSHPark driver, but I can wait for the review or tear down if need be.
Thanks Again!
