Strobe 2200lm

First Look :

Flashlight in it’s box , a nice brown box :

Package Contains :

  • Flashlight
  • Lanyard
  • O-ring
  • Pocket clip

A closer look :

You can see the front side of the flashlight , with the e-switch visible .

Notice the nice copper head :

Comes with 2 different tubes , one for 18350 and one for 18650 :

A comparison of the light with 2 batteries :

Button top 18650 batteries are a tight fit in length :

Manker E14 II and Astrolux K01 :

Astrolux S41 with some patina and Manker E14 II with 18350 tube :

The led’s on the front , 4*xp-g3 with a TIR optic :

Body has knurling that makes the surface grippy :

Tailcap , it has a nice design :

Threads are square and anodized :

Coming soon…

Here is the clip that comes with the light , it can be installed in both ways :

Inside the tailcap , a pcb with a double spring :

If you unscrew the head , there is a micro-usb charging port on the tube , to charge the battery inside :

And inside the tube :

When charging , top side lights red or blue , red when battery is charging and blue when it’s full :

Here is the driver side , with the little brass button :

How it works (&modes) :

When the flashlight is off, click one time to access the moonlight mode , with at least another click circle: moonlight – low – high. Long press to turn it off.

Shortcuts , from off :

  • Long press the button to access to the mode your last use
  • Double click access to Turbo

Engineering mode (Chose output level for moonlight mode):
Quick click for 4 times from any mode to get access to engineering mode. Once click to check different levels and long press to make your final choice.

Here is a diagram from Manker :

Measurements :

Samsung INR18650-30Q

Lumens :

  • Moonlight – 1 lumen
  • Low – 15 lumens
  • Medium – 152 lumens
  • High – 695 lumens
  • Turbo – 2803 lumens

Current draw , in standby mode (parasitic drain while flashlight is off) : Coming soon…

Intensity : Coming soon…

My test , with thermal data :

Turbo mode :

Teardown :

Bezel is not glued , and by removing the optic we can see the leds :

MCPCB is copper dtp . As you can see , driver wires are connected the other way around , because leds are reflowed the other way too . Basically this was done intentionally to prevent short circuit if something goes wrong .

And here is the interesting part !! Driver is a fet+1 driver , in 2 stacked pcb’s . Bigger pcb is 20mm …

Bottom board . We can see the fet , the 7135 and a capacitor :

And here is the top (second) board with the rest of the parts , the diode , the attiny13a , another cap and the e-switch :

I’ll be probably post a ramping firmware here , for those who want to mod their lights Wink

Beamshots :

Wall @ 12m :

Control shot :

Turbo :

High :

Conclusion :

An awesome pocket rocket , well designed / materialized flashlight which can provide a great amount of light if needed (= not for super long time) , with an interesting interface and different moonlight levels to choose from !

Comment if you want me to check something on the flashlight , or tell your opinion . Thanks !

Flashlight was provided for review by Manker . Check out the light here : Manker E14 II .

Thanks for the review.

I prefer the charging port to be accessible from the outside of the light. I know, less water resistance. But I rather not have to unscrew the light every time I need to charge it.

The Astrolux version has the charging port accessible without unscrewing the head. Rumor has it a version with an aluminum body and copper heatsink like the S41 and this Manker is coming soon.

Thanks for review!!
For me this type of charging port have the advantage of better water proof than the external ports covered by perhaps not reliable rubber pieces.

( I am using my unit with 18350 IMR Aw and IMR Nitecore 18350 most of the time)

Thanks for a great review. I am glad to see that they have stopped using the glue.

Thank you giorgoskok! Thumbs Up

Do you see signs of the clear coat in any way, on the copper head?

This is most certainly on my ‘soon to-get’ list. I LOVE that it has two pocket clip grooves also.

I am thinking about tearing mine apart, and removing the (reported) clear coat. So I can get a tad better cooling, but more importantly. That all so wonderful patina, later on down the road. Cool

Thanks for your kind words !

I was excited with the driver , now that it is a fet+1 and charging is in a different circuit someone can have a ramping firmware without a stepdown for the cost of 1-2 resistors (for the lvp) Silly

Yes it has a very thin layer of clear coat or something similar .

I polished my S41 and created a patina , the one in one of the pics , it has a cool uneven patina … (i will try to get a better pic )

Yes, I saw that. It really is getting a nice look to it.

Did you take that coating off with some MEK solvent, or did you just buff it off with a wheel polisher?

Thanks for the review (in progress). I see the great performance of this light but can not get over the looks, it is plain ugly to me Innocent .

I see that the head does not have the rim that the opic can sit on (the fix that Astrolux had for the S41S) and that prevents twisting the optic when closing the bezel. So a modder’s question: are the dimensions in this light such that the optic is the correct height above the leds without damaging the domes, and that the bezel can be closed without chance of shearing off the led domes?

If i remember correctly , optic sits better than S41 , sits all the way down …

I’ll be disassembling the light to flash another firmware , so i’ll post pics for that matter Djozz , just to be sure .

That stepdown is ridiculous. It’s reasonable enough for a FET quad to have a significant stepdown, but to less than 10%? Good thing it isn’t too hard to get to the MCU and flash a different firmware.

I completely agree. It is ridiculous. I mentioned it in the Manker thread, and haven’t gotten a response back.

I think you should have a look again. In the description is says goes to high mode after 40 secs of turbo. They even replied saying in the final version that’s how it’s gonna be.

This light needs better regulation. After 40 seconds on turbo, it steps down to almost 100 lumens. It also needs a mode between turbo and high, like a high 2. If Manker addressed those issues, this light would be fantastic.

E14 II final products Turbo: 2200 lumens last on 40 seconds then stepdown to 850 lumens

Ah that sounds much more reasonable. Slightly lower peak turbo coupled with a much more reasonable stepdown.

I have one on order set to arrive end of next week! Cool

Lucky you. I got the s42 instead because of price. I think the manker version is so much better looking.
Did you get the XPG3 Or Nichia?

A batch of these Manker E14 II’s have made their way the the U.S. this week, Wednesday. But with the Blade Show going on in Atlanta, Friday through Sunday. No one has had time to unpack them yet. Tired

Long time flashoholic here and first post on BLF.
I ordered a Astrolux S41 and 2 days later I saw the Manker E14ii was coming out so I ordered one from Manker before they even had it on their site. The light arrived today in a production box(smashed) not a plain brown box. I got the Nichia version and my step down happens at 1 minute and it steps down to high mode not the 100 lumens. I was worried about the 40sec step down to 100 lumens and had ordered the light before they listed the specs. I also wasn’t sure if the Nichia version would be 4000k HCRI or the 5000k 80 CRI. I received the 4000k. Just thought I’d share for anyone interested in the light as I was worried what tint and the step down.

Thanks! I’ve been really curious what they did with the driver, and now I know. Smile

If the Astrolux version uses the same driver, it could be a decent mod-friendly e-switch host. Manker’s version seems a bit funky though.

I already made a hex file of a ferrero rocher ramping firmware without led indicators , and i should test it soon on the light .

That’s what I put on my mother’s SRK. I would rather have used Narsil, but I only had a tiny13 available so I went with the closest thing I had.

BTW, Ferrero Rocher still needs a bug fixed… the ramp direction doesn’t always go up when long-pressed from off. And it also otherwise doesn’t reset the direction when off. IIRC, I tried to fix it 3 years ago but it made the ROM exceed 1024 bytes with indicators enabled, so I didn’t keep the fix. So… that’s a thing which could really stand to be changed as soon as I have my office reassembled.

Oh, um, and Ferrero Rocher never did get FET+1 support. It’s so old that those didn’t exist yet. That’s probably a lot more relevant than a minor ramping quirk, and modernizing the code will involve some slightly deeper changes.

Thank you for information. I hope you are satisfied with your purchase.

I want to buy this too but I have a question.

This is 219c 5000k:

This is 219b 4500k:

Since you have received 219c 4000k. I want to know that which is more similar to that.

It’s closer to the 4500k of course , and difference will be small .

I more likely want to find out how its tint is closer to the characteristic 219b tint (some call it rosy tint).
