PACKAGE & FLASHLIGHT

Banggood was kind to provide the flashlight and the long tube for this review! It arrived in 7 days to my door! All was nicely packed and protected by foam.
Inside, 2 boxes, one for the 2 AA tube and one for the flashlight and other accessories!

Inside the cardboard box, wrapped in foam, can be found: 1 BlitzWolf BW-ET1; 1 plastic white diffuser; 1 lanyard; 2 o-rings; 1 user manual; 1 warranty card. And 1 silica gel bag Big Smile

On the other box, the 2 AA tube, inside a plastic bag!

—————————————————————————————

THE FLASHLIGHT

The BlitzWolf BW-ET1 is a well-built and strong-bodied flashlight, with smooth anodizing that makes it soft to the touch despite the knurling on the battery tube and the fins on the head.

Note the + on the bottom of the head/top of the tube, to indicate battery’s polarity.

Being an AA/14500 flashlight, this is not a small or thin light. Well, it is the biggest I have that uses those types of batteries, as I’ll show later…
As a comparison, the head diameter is larger than a Convoys S2+ Shocked

Also, due to its composition and strong/thick body, it is not a lightweight flashlight! Here it is without ( L ) and with battery [Sofirn 14500 Li-Ion battery] ( R ).

The BlitzWolf BW-ET1 is composed by lots of parts/pieces. I didn’t fully dismantle the head to access the driver, but here are the pieces that one can reach.
It is constituted by: bezel; AR coated lens; o-ring; smooth reflector; head; battery tube; and the taicalp.

—————————————————————————————

HEAD

The side switch is made of rubber. In the head there is a metal plate with 4 screws that (probably) allow access the driver and/or the switch. Everything seems to be well tight and sealed to prevent from entering water or dust.

The driver seems to be pressed or screwed in towards the top as there is no retaining ring on the bottom of it.

The XPL V6 LED has a black plastic gasket surrounding it and aligning it with the reflector. The gasket has an uncommon shape (at least to me) as it is placed all over the MCPCB. Both wires are placed below the gasket.

Despite I didn’t took the gasket out, it is possible to see that the emitter plate (probably copper MCPCB) is glued with withe glue.
Also note the cooling fins to help dissipating the heat from the LED.

As mentioned, below the aluminium bezel, lays an AR coated lens.

Well, and below the AR coated lens, we have a well-made aluminium smooth reflector. Due to its shape and the gasket there is no contact between the wires and the reflector.

—————-///—————-

TUBE
The single battery tube of the BlitzWolf BW-ET1 has a flawless knurling outside. The tips of the tube are different and the tube is not reversible. Towards the tail, the tube’s threads are longer and anodized; towards the head, they are shorter and non-anodized. Both interior edges are non-anodized as well. Each tip has a sealing o-ring.

The tubes were not much lubricated when the flashlight arrived, so I applied some grease.

—————-///—————-

TAIL
The tailcap of this flashlight is full of pieces: tailcap, lanyard ring, neodymium magnet, o-ring, cap. It is possible to remove the magnet and the lanyard ring without much trouble and the tailcap and flashlight keep on working perfectly. The “tailcap of the tailcap” has a smooth knurling pattern, less deeper than the battery’s tube.

The lanyard ring can is not tight so it can be freely rotated around the tailcap.

Inside the tailcap, there is a tough golden spring, soldered to a PCB, that lays below a (un)screwable brass retaining ring.

—————-///—————-///—————-///—————-

ACCESSORIES
Now, let’s check some of the accessories that this flashlight comes with!

2*AA TUBE
The “double tube” of the BlitzWolf BW-ET1 can be bought together or separately from the flashlight. Here is the link (non-affiliate) for the tube only: https://www.banggood.com/Blitzwolf-ET-1-LED-Flashlight-Extension-Tube-fo...

Please note that it arrives with a warning sticker (!!!) in which is written:
Do not use with 2 lithium batteries!!!

Like the smaller tube for 1 battery, the “double tube” is thick, has knurling on the exterior, non-anodized edges, 2 o-rings in each tip, and is non-reversible.

BUT, unlike the smaller tube, the “double” has a pocket clip that can be installed near the tailcap. The tube has a specific groove for that, and it can only be applied on the bottom of the light.

This is how the flashlight looks like with the “double tube”!

Being a thick tube, it adds more weight to the flashlight! Here it is, without batteries and with 2*AA alkaline inside.

—————-///—————-

DIFFUSER
One nice extra this light came with is the white diffuser!

Giving the possibility to use this light with 2*AA batteries for almost 300 hours in moonlight mode, the diffuser is an excellent accessory to use the light as a candle! Well thought BlitzWolf!

—————-///—————-

USER MANUAL and WARRANTY CARD
The user manual is quite simple. It provides basic information, but probably not all the information we are used to see in flashlight manuals!
Despite that, it is well written and helps understanding the flashlights operation!

From the Warranty Card we have to maintain the 18 months warranty!

And…BlitzWolf added some fun in the “wolf paws” Big Smile

—————-///—————-///—————-///—————-

USER INTERFACE

BlitzWolf BW-ET1 flashlight’s User Interface is quite simple, but has some nuances.

First thing to say is that the flashlight has memory for the ramping levels (Strobe and Turbo are not memorized), so it will turn ON in the last used mode, unless the power connection is fully broken or interrupted physically.

Single click to turn the flashlight ON or OFF.
When ON, press & hold the switch to enter ramping (also called “Stepless Brightness Adjustment”).

Ramping
When the light is turned ON in the lowest mode, the ramping will go UP.

If the light was turned OFF in another level – that was reached and memorized by going UP or DOWN in ramping – when turning the light ON and ramping, it will move in the opposite direction.
Also, if the ramping is interrupted (releasing the button), when the switch is pressed again, the ramp will start in the opposite direction.

EX: Ramp UP > release switch OR turn OFF > press & hold switch again OR click for ON + P&H > Ramps Down

—————-

When Ramping UP or Down:
> 1 blink marks the lowest level
> 2 blinks mark 50%
> 3 blinks mark the Highest level

The Ramp stops on the Top and Bottom levels!

—————-

Double click from ON or OFF for Turbo.
When in TURBO, a single click turns the flashlight OFF.
When in TURBO, a double click returns to the previous level (or OFF).
When in TURBO, a triple click goes to Strobe.
When in TURBO, press & hold starts ramping down.

—————-

Triple click from ON or OFF for Strobe.
When in STROBE, a single click turns the flashlight OFF.
When in STROBE, a double click returns to the previous level (or OFF).
When in STROBE, a triple click maintains on Strobe.
When in STROBE, press & hold starts SOS.
From SOS, press & hold returns to Strobe, and the other commands operate like when in STROBE mode.

—————-

One trick: twisting the head and cutting the power OFF while the flashlight is ON, resets back to the lowest mode when turning the flashlight ON again Wink

—————-///—————-///—————-///—————-

TINT and BEAMSHOTS

As stated above, the BlitzWolf BW-ET1 has a 5000K XPL V6 LED, an SMO reflector and AR Coated Lens.

This combination produces a beam with a well defined but not very intense hotspot. It means that at close distance there is not much problem because the hotspot will not “blind” the user, but at distant range, it looses some throwiness!

Despite the BW-ET1 has a “nice” tint, against a white wall or surface, it produces some tint shifts.
Not all will be visible on the photos due to my cellphone quality and due to image conversion.

What can be seen in naked eye is:
a) the very center of the hotspot is white and yellowish
b) the corona has yellow, greenish and white, and seems to have a “flower” with 4 leaves in format of cross (see the picture on the right, above the LED);
c) near the corona, the spill has some yellowish and then its mostly whit till the limit of the beam.

There are no visible signs of PWM with this flashlight. However, here are some close-ups above the LED on the lowest, the 50% and the highest levels.

—————-

Also, here is a tint comparison with other lights! (Left to Right)

BlitzWolf BW-ET1 >>> Sofirn SF14 >>> Manker E11

BlitzWolf BW-ET1 >>> Sofirn SF14

Amutorch S3 (Nichia 219C) >>> Sofirn SF14 (XPG2 NW) >>> BlitzWolf BW-ET1 >>> Manker E11 (XP-L CW) >>> Olight S1R Baton (XML2 U2-1A)

—————-

And now, some beamshots at close and distant range:

- 20cm from the wall (14500 Li-Ion; L > 50% > H)

- 1.5 m from the ground (14500 Li-Ion; L > 50% > H)

- 4 m (14500 Li-Ion; L > 50% > H)

- 5 m (2*AA Alkaline; L > 50% > H)

- 5 m (14500 Li-Ion; L > 50% > H)

- 6 m (2*AA Alkaline; L > 50% > H)

- 6 m (14500 Li-Ion; L > 50% > H)

- 10 m (BlitzWolf BW-ET1 >>> Sofirn SF14 >>> Manker E11)

-25 m (house) (BlitzWolf BW-ET1 – 2*AA >>> BlitzWolf BW-ET1 – 14500 >>>Sofirn SF14 >>> Manker E11)

- 35 m (factory) (BlitzWolf BW-ET1 – 2*AA >>> BlitzWolf BW-ET1 – 14500 >>>Sofirn SF14 >>> Manker E11)

- 50 m (factory) (BlitzWolf BW-ET1 – 2*AA >>> BlitzWolf BW-ET1 – 14500 >>>Sofirn SF14 >>> Manker E11)

- 90 m (house) (BlitzWolf BW-ET1 – 2*AA >>> BlitzWolf BW-ET1 – 14500 >>>Sofirn SF14 >>> Manker E11)

—————-///—————-///—————-///—————-

SOME CONSIDERATIONS

What I liked?
- Shortcut to turbo (double click) – Obvious, I like this feature in any flashlight Wink ;

- Shortcut to strobe (triple click) – Strobe and SOS are hidden, and won’t turn ON easily;

- Strong magnetic tailcap, even with the long tube and 2 AA batteries inside – It can be nice while using the flashlight on work or as a candle, free-hands;

- Overall machining and anodizing – The flashlight is really well made, almost built like a tank, and seems to be capable to get beaten by flashaholics and non enthusiasts;

- Possibly an efficient light in the lowest mode (and on others) – The general specs seem to point that way, giving a long runtime, specially on Ni-MH or even alkaline batteries

—————-

What I thing that could be improved?
- No shortcut to lowest mode through the switch – It would be nice to have quick access to lowest mode without having to twist the head/tube…

- No pocket clip for the short tube (1 battery) version – It would be nice to have a groove in the single battery tube for a clip, specially considering the size of this light…

- No “real” low voltage protection – It seems to me that if we use unprotected Li-Ion batteries, we may have some troubles as there is no alert when the battery reaches low voltage levels. The same thing possibly applies to Ni-MH or other rechargeable compatible batteries. At least, on the specs, this is not mentioned.

- No battery check for rechargeable batteries – More or less like the point above: for lithium cells there should be a way to check battery status, other than the 3.4V threshold that hinders to access Turbo mode.

- No possibility to use flat top batteries – Luckily I have 2 button top batteries (unprotected) and was able to use this light. No reference is made on the User Manual to this situation.

- Possibly some parasitic drain? – There is also no reference to parasitic drain. I don’t know if it exists of not, and don’t have a way to measure it, but it would be nice to have an idea of this given by the manufacturer.

- The ramping mode – If the ramping is a nice feature on this light, it is also a bit annoying, specially after trying other ramping flashlights. From the lowest level to 50% and from here to the highest level, it seems to take an eternity, both on AA and 14500 cells. To have a faster but still easy to control/accurate ramping mode would be good and would make this flashlight more attractive

- The switch – In my “sample” , the switch is not always fast to respond to my press & hold to ramp up, specially when turning the light ON. Maybe this is my defect, but it happened several times. Maybe other owners can say something about this!

- The size – Despite I know this is a very solid, robust and well made flashlight, it seems to me that the overall size for a AA/14500 flashlight is…way to big! But, I recognize that it won’t get easily lost on the pocket due to this Big Smile

—————-///—————-///—————-///—————-

EXTRA PHOTOS Wink

Batteries! Well, you read that, no smiles for flat tops Facepalm

But…that tail can handle the smallest and the biggest version, fully loaded and working Big Smile

Me, daring to use the “double” tube pocket clip, on the single tube form Silly

The BlitzWolf BW-ET1 as the biggest brother of the AA/14500 family…

… and as the cousin of other types of battery flashlights! Cool

Thanks for reading!
And thanks Banggood for the opportunity to review this flashlight!

Best regards to all Thumbs Up

Today I picked the BW-ET1 and tried to check on the lowest and highest levels, with 1*14500 Li-Ion battery and 2*AA alkaline batteries. Here are the results at +- 1.5m from the wall!
I have no means to measure the lumens, but I remember the “supposed” levels:
a) lowest mode on 14500 battery – 2.5 lumens
b) lowest mode on 1 or 2*AA batteries – 0.2 lumens

Also, the BW-ET1 2*AA version vs the Olight S1R Baton on moonlight modes (supposedly: 0.2 Lumens vs 0.5 lumens, respectively left and right).

It seems to me that the lowest level on the BlitzWolf is a lot higher than advertised, both on 1 or 2 AA batteries. It is similar to a 14500 battery, as it can be seen on the 1st and 2nd photos.
Also, comparing to the 0.5 lumens of the Olight, the BW-ET1 clearly has a higher lowest mode!!

I didn’t make this comparison earlier, but it had to be done as a way to compare specs and actual performance !!

I honestly disapointed with this light even though i got it with discount.

The brightness with AA battery is dim comparing to other AA lights now day and the ramping is awfully slow. I rather have normal modes than slow turtle ramping .

thanks for the review though Davie

Thanks for your words! Thumbs Up
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 Wink

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

!{width:50%}https://farm1.staticflickr.com/801/27468432978_c7fd465c23.jpg!

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… Facepalm

About the size…I dare to say that this is a hardly “hideable” flashlight Big Smile I do like the robustness it has, though Wink

Once again, thanks so much djozz!! Feel free to post any information you find useful to enrich the data about this light Thumbs Up

Thanks for the review, MascaratumB Thumbs Up

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 Smile

Hum, didn’t know that! Perhaps it can boost the turbo level a little bit? Evil

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 Wink

Blushing Ai, it appears that I messed up rather than Blitzwolf Facepalm , 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! Facepalm
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 Facepalm ) : 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… Silly

Thanks again djozz!! Thumbs Up

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 Big Smile

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

WalkIntoTheLight wrote:

Output: Max 150 lumens (AA), or 500 lumens (14500). Low 1 lumen (either battery type). Stepless for everything in-between. Graph included below. Output is flatly-regulated, except for a pre-programmed step-down from max.

Run-time:
Max (AA) – 4 hours on a 1900mAh Eneloop, but because of a step-down this is mostly at a 75 lumen output. 9 hours run-time on 2xAA.
Max (14500) – 1.25 hours, though the step-down means that most of this is at a 250 lumen output.
Moonlight – 250 hours.

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.

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 Sick

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” Silly

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… Ughh

Ahah, thank you Big Smile I will change the title to avoid confusions Wink

Hum putting this light working with 2*14500 batteries….that would be nice Evil 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 Facepalm

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 Glasses

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 Big Smile

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 Big Smile
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 Flat Stare

I’ll examine mods with other e-switch drivers to check if this light would take one…maybe for 1 or 2 14500 batteries Evil

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 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!! Flat Stare

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 Facepalm

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 Thumbs Up
