Very nice review, thank you.
Thanks for your words! :+1:
Well, in some way I feel like you, specially the ramping speed. I like that we can control the level where we are at, but then…it is sloooow!
Lights that have “automatic” stepless dimming (Jaxmnve M3, even the Wuben TO10R) annoy me more because we can’t control the level in an accurate way!
About the luminous level…yup, I guess that with a single or even 2*AA it could be higher. Despite I got this light for “free” I must say that.
It is a nice light to have around to use with 2 batteries on the candle mode, as it will last for a while 
Thanks for you words
I picked one up at discount too and am not overly happy with it, mainly because of the size.
To add to your review, I just measured some output numbers. I must say they messed that up bigtime in their specs!
edit: sorry, it was me who messed up, see a few posts down
Wow djozz, thanks for these values!!!
Hum, I have one doubt (or one need of clarification) though: the “303” corresponds to the max output (lumens) after 30 seconds with a Li-Ion battery?!!!
That is impressively low comparing to what is presented in specs!
I ask this because the Sofirn SF14 specs point to a max output of 600 lumens (on a 14500 Li-Ion), just like the BlitzWolf BW-ET1, and on the night I took the photos, I tried both, side to side and they seemed very similar.
At naked eye and no measurements, the BW-ET1 - on Turbo with a Sofirn 14500 battery - is pretty similar to the Sofirn SF14, on max output with Efest IMR14500 650mAh (purple) - both on beam “intensity” and throwiness. (Despite the XPG2 of the SF14 produces a slightly more intense hotspot)
As I mentioned, I have no means to compare both objectively and to provide numbers, but if these 303 lumens are real after 30 seconds…I wonder if it ever gets close to the 600 advertised lumens… :person_facepalming:
About the size…I dare to say that this is a hardly “hideable” flashlight 
I do like the robustness it has, though
Once again, thanks so much djozz!! Feel free to post any information you find useful to enrich the data about this light :+1:
Thanks for the review, MascaratumB :+1:
Hmmm… 3.4V boundary between Li-Ion and AA performance. Energizer 1.5V lithium primaries are 1.8V when brand new -> 3.6V for two. Just a random thought 
Thanks Phlogiston
Hum, didn’t know that! Perhaps it can boost the turbo level a little bit? :smiling_imp:
There is not much information about the stepdowns in terms of time, only Voltage, so it may be shot to try those and see if the hang for a bit
Ai, it appears that I messed up rather than Blitzwolf :person_facepalming: , I assumed that the highest setting was the top of the ramp but it is not, a double-click gets you a higher setting (this is not clear from the manual btw). I hope the lowest level is still the bottom of the ramp, or is there also a trick also to get further down to the spec’ed 0.2 lumen?
Corrected numbers:
Li-ion
Lowest 3.2 lumen
Highest 495 lumen
NiMh
Lowest 2 lumen
Highest 150 lumen
Oh, well, and I also missed that in the review! :person_facepalming:
I will check toninght when I have the flashlight with me, as I can recall correctly about this situation!
The bottom of the ramp, as far as I perceived, is the lowest one. If you ramp down, when reaching the bottom the light will blink 1 time.
About the top, it blinks 3 times, but I don’t remember if there was a visible difference between that top level and the turbo (through double click).
In any way, 495 lumen is better than the earlier numbers you gave, of course!
But now I ask again (because I have no idea :person_facepalming: ) : droping about 100 lumens from 0 to 30 seconds, with a fully charged Li-Ion battery, in a light like this, is it normal?! This is, assuming that the initial really were 600 lumens… 
Thanks again djozz!! :+1:
I checked once more the purple Efest, extra topped up on the charger now (first measurement was with a few days rested battery), and it helps a bit: 540 lumen at 3 seconds, 520 lumen at 30 seconds.
And I could not resist this pic, I will add that including li-ion batteries the Blitzwolff is 89 gram, the D4 112 gram. I will spare the Blitzwolf any further comparisons
Ehehe, I compared it with a Convoy S2+ and the BW is larger
Thanks for the final numbers. It may not be 600 but it is closer !
My feeling is that it could be different in many aspects and if BlitzWolf wants to make nice things, they can keep the robustness of body, but the size, and even UI and / or driver must be different!
Well, at least for some of us enthusiasts
Thanks again djozz
I’ll second that. Reading this part of WalkIntoTheLight’s review was an eye-opener:
It basically ended my interest in the light, because the stepdown from maximum is hardwired to kick in even with the AA cell(s). Completely unnecessary.
I’m not sure about the ramping interface, either, but I might have given that a go if it hadn’t been for the AA stepdown.
By comparison, the Sofirn SF13 I ordered during the AliExpress anniversary sale - I haven’t had the light in my hands yet - is supposed to do 420lm on 2×AA and step down to 196lm after 3 minutes. Even the stepdown is better than the Blitzwolf’s 2×AA maximum.
thanks for this comparison and review. 1/2 AA had me thinking half AA 14250
lets hope someone with good electrical background can analyse the driver and find a way stacking resistor to get more current to the led.
im hopeless but will give it a crack :confounded:
Yup, I guess the Sofirn SF13, Jaxman M2, Zanflare F2, Manker E12 and other similar 2*AA lights are probably “better” than this one, in output and eventually in other aspects.
If we don’t compare it with the others, this light has a nice lowest mode, theoretical UI (except for the slow ramping) and nice “body”, but having many others, it gets hard to say this is “awesome”
One advantage I can see is that this one can be “elongated” or “shortened” if we want! (not sure if this acts as a Pro, but it still is a nice feature).
Still, other aspects… :disappointed:
Ahah, thank you I will change the title to avoid confusions
Hum putting this light working with 2*14500 batteries….that would be nice :smiling_imp: Muahahaha!!!
Or just making it work better with a single cell…
I guess that I will try to dismantle mine, just to check its “entrails” ! I’ll post photos later (maybe tomorrow, if I manage to…)
Could someone get two spacers and run 3 * AA in this light?
Yesterday I picked the BW-ET1 and “tried” to dismantle the head to accesse the driver…
But…this is what I found :person_facepalming:
Sorry, but not even in the name of flashlight science I will pass this stage, I would probably ruin the driver and the light!
maybe later, if I have the guts to do so, I will rip it off in any way :nerd_face:
wires are still in contact with driver and it should still work…. dont panic
i mod many lights with e-switch and it’s normal
Yeah, it works perfectly, but the driver has all that white glue or silicone or whatever, so I didn’t push or pull anything!
It was a open and close surgery only
I thought it was more “clean” to get to the driver, but…I was wrong!
If I was sure that any of Lexel’s driver would work here (and if I was sure that I would put this back together), I would try it but this way…
I’ll think about it for a while
it looks like they injected glue inside to driver to hold the driver in place.
Most flashlight have retainer ring on the driver to hold them in place 
Yup, precisely, I thought that even with the retaining ring it could be a “press fit” driver, but it is full of glue.
And the glue seems to be tough, not soft one…
I’ll see if I manage to unsolder the switch, take the glue of and then, see if I can get the driver OFF.
But…the MCPCB is also glued… So, I expect this to be quite messy 
I’ll examine mods with other e-switch drivers to check if this light would take one…maybe for 1 or 2 14500 batteries :smiling_imp:
