Looks like it already will have copper DTP.
So this is begging for a driver upgrade!
22.5 mm is the outdiameter of the head,not the anti-roll hex. Thank you.
This is what impresses me about Jaxman products. The quality is fantastic. They reveal the internals as well. This is something most manufacturers do not reveal.
Waiting for the host version!
I really like the new driver with moonlight mode and no memory.
Any chance of get this driver also with the host?
Just received new version of E3 without memory. Measured tailcap currents on charged and rested batteries:
| mode and battery | clamp meter | multimeter |
| mode 1, liion (1) | 0.58A | 0.47A |
| mode 2, liion (1) | 0.96A | 0.81A |
| mode 3, liion (1) | 1.7A | 1.53A |
| mode 1, liion (2) | 1.0A | 1.0A |
| mode 2, liion (2) | 1.6A | 1.3A |
| mode 3, liion (2) | 2.7A | 2.3A |
| mode 1, eneloop | 0.04A | 8.6mA |
| mode 2, eneloop | 0.35A | 47.3mA |
| mode 3, eneloop | 2.3A | 2.3A |
| mode 1, alkaline | - | 9.5mA |
| mode 2, alkaline | - | 53.2mA |
| mode 3, alkaline | - | 2.3A |
Ai, on li-ions the modes are way too close together, with no proper low, they placed their bets on NiMh’s and alkalines.
Can anyone post any beamshots please? 
Thanks for your numbers g_damian :+1:
Yes thanks for the tailcap currents :+1:
mode 3, eneloop………2.3A
mode 3, liion (2)……….2.7A
So Li-ion doesn’t offer much more brightness vs NiMH?
(1) is rested cell and (2) is fully charged? What is the voltage of rested?
W=A*V
So Li-ion is a lot brighter, because 2.7*4>2.3*1.35. (also note voltage of batteries)
(1) and (2) are two different 14500 cells, both charged. (1) is protected, (2) is not.
Ok thanks, I didn’t consider the voltage :person_facepalming:
So the NiMH only produces around 3.1 watts, and the Li-ion produces around 10.8 watts?
I got my new version E3. I like it a lot and it would be a candidate for my favorite AA/14500 flashlight, except when I use a 14500 cell all the modes are very close in brightness to max (not single mode, all 3 modes are different, albeit barely). I wonder if this is the intended behavior or my unit came defective
I really like my E3 alot. It has a very nice tint, which is rosier than most 219C I’ve seen. The start on moonlight mode and 3 brightness mode makes this a very user friend AA flashlight. If I were to choose the best AA flashlight to give muggles, I would choose either the E3 or the Reylights. Both perform about the same in terms of brightness but the Reylight looks alot nicer for 4x the price.
SKV89 does your E3 have the same mode spacing issue (when running on Li-ion) as Persechini reported in the post above yours?
Yes same issue. Fortunately the AA mode is pretty bright. If I want a bright 219C 14500 flashlight, I’ll use the Reylight Ti Lan or Pineapple.
That means it’s a lottery with the tint?
I also ordered Jaxman E3 4000K, but the tint isn’t that great (sort of yellowish), definitely not rosy (unlike one of my BLF A01 which has a really rosy tint)…
Will post a pic to compare them…

With regards to brightness level when using 14500. While I could measure a difference in tailcap current from Low-to-High (it’s similar to the one mentioned above), the brightness (using our eyes) from Low-to-Medium is very little difference. While Low and High (although there’s a bigger difference in tailcap current drain, the actual brightness difference seen by my eyes is also not that big a difference. The flashlight does get hotter much more quickly when using 14500 in High mode though).
Unlike when using AA, there is a nice spacing of brightness levels from Low to Medium to High (I think the AliExpress website indicates it’s supposed to be 1-60-350 lumens? Anyone can confirm if those are the real values?) I wonder what is the actual lumens rating when using 14500 — maybe someone who knows how to measure lumens can answer it (I have a basic lux meter now but don’t know how to compute/convert that to approximate lumens…)
It’s rosy compared to other 219C but not as rosy as the 219B 4000k an definitely not as rosy as my Emisar D4 5D tint, which has a tint that is almost pink.
I will post some comparison ceiling bounce values with other AA lights later.
Hmm, so mode spacing using 14500 is not exclusive to my unit, it’s either a manufacturing issue or a design issue
As for tint, mine is quite neutral and pleasing, not particularly rosy, definitely not greenish or yellowish
It is most certainly a design issue. I think it takes quite some electronics and software expertise and probably extra components on the driver to get the modes right for both AA and 14500 when not all modes are made by PWM (the low mode isn’t). They chose to get the AA modes right and left the 14500 modes for what it is and that is understandable.
Is the Li-ion mode spacing problem because of the current? So there would be the same (or near the same) problem with NiMh eneloop?
Cheaper lights I have offer better aa/14500 versatility. This one kinda disappointed me, it should be advertised as AA only
