“REVIEW”: BlitzWolf BW-ET1 – 1 or 2*AA /// 1*14500 Flashlight – 600lumens [PIC HEAVY] ***(+ discount codes)***

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… :stuck_out_tongue:

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 :smiley:

Ehehe, I compared it with a Convoy S2+ and the BW is larger :smiley:
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 :wink:

Thanks again djozz :wink:

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” :stuck_out_tongue:

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 :smiley: I will change the title to avoid confusions :wink:

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… :wink:

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 :smiley:

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 :smiley:
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 :wink:

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 :beer:

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 :expressionless:

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:

It doesn’t look like it to me. Looking at MascaratumB’s photos, both tubes have external threads at both ends. To be able to chain tubes for 3×AA, each tube would need to have an internal thread at one end and an external thread at the other.

I like the idea of a 3×AA light, too :slight_smile:

The original Olight S15’s could use 3 AA’s with extension tubes.

Just ordered the Blitzwolf flashlight. I’d rather have that not be glue under the power button. Maybe it could be thermal grease?
Nice overall review.

Hum, my guess is that it is glue, not thermal grease! It is very dense inside the head host, and it can even be seen next to the MCPCB.
I believe that it is some sort of glue or silicone, maybe. It may take a while to take it out , in case of doing some mods!! :expressionless:

EDIT: And thanks for your words :wink: :blush:

Thank you - I had a vague memory of a light like that, and the S15 is the one I was thinking of. If memory serves, when Selfbuilt reviewed it, he found that it was OK with 1×AA and good with 2×AA, but strangely inefficient with 3×AA.

I didn’t see the point of that, so I never bought one. If I’d been thinking, I’d’ve bought one and used it with all the extensions, but only 2×AA and an AA short-circuit spacer. I like long lights, I always feel like I’m going to fumble anything less than about 125mm.

In name of the flashlight science…I endep up opening the BlitzWolf BW-ET1 :person_facepalming:

Here are some photos after opening it!
Major surprise for me: the LED plate is not MCPCB, it is 1mm aluminium thickness, 16mm diameter .
All that stuff was “glued” with some sort of silicone. It was easy to remove it from the driver, after I took it out.

I ended up damaging the driver a little bit.

BUT, I have a major question now: where can I find a 17mm driver that will fit this light (and that can be “attached” to the side e-switch ) and that can be used with 1 or/and 2 14500 Li-Ion batteries?

I wanted to do one of the following things:
a) turn this into a triple, or,
b) use this with a XHP led, or,
c) simply used this with a LED that can be used with one or 2 Li-Ion batteries!

I am ignorant about some of these things of drivers, so I appreciate some help on what can be done to mod this light :wink:

Thanks in advance :+1:

lexel can build a driver your u 2 x14500 Li-Ion to run XHP with narsil ramping UI.


it should cost around 15 bucks

Hum, gotta make some measurements then! :+1:
I tried a 17mm driver I have from Lexel, and there are 2 problems: the driver’s width must be bigger (18 or 19mm, or eventually 20mm so that it fits perfectly on the head); the driver must be single sided :person_facepalming:

I don’t know if he does single sided drivers, but the chips on the back of the driver will certainly be a issue to make this mod!

BUT I like the idea of having Narsil running on this and a XHP (maybe XHP35 - HI or XHP70.2 NW) on this!

Thanks for the tip Nico :wink:
