Tear Down: Manker E02 / E02H (same as E03H)

Thanks, nice pics. Very, very interesting, great aaa flashlight, no doubt!

Awesome! Have you torndown an E01 yet?

Thanks :+1:

I have an Astrolux A01 form the first batch, which is (i think) identical to the Manker E01, including the lovely tinted 219B.
It’s a pretty straight forward construction:
Pill screws in the head, pushes lens and reflector forward.

yep, that is how my Manke E01 went together

So, i was messing around with a small TIR optic, and then i destroyed the XP-G3…
This was a while back actually.
Today i decided to remove the XP-G3 remnants.
I can confirm the copper heat sink protrudes through the PCB, giving the LED a direct thermal path. :+1:
The XP-G3 was badly soldered to the heat sink though, but probably good enough for the <2 Watts power consumption.
I just finished reflowing a 219C 4000K CRI90 onto it.
First the centre pad to the heat sink, and then the + and - traces from the sides.
(had to scrape some masking paint off the PCB first)
…it could still do with a diffuser though…

How did you remove the old Led and reflow the new one? there are many other components around it. I really want to replace mine with a nichia 219 R9080 but still can’t open the light yet

Are the threads of the head of the light glued to the battery tube threads? I can't open my E03H by hand.

How did You manage to screw out the bezel ring?
My E02 is not so well centered and I’d like to justify it. But I cannot remove the bezel ring…
…well, without tool. But I avoid using any metal tool because I am sure it will scratch / dent the ring.

Sorry but this pcb look like amateur project. Solder bulbs and dislocated parts are ugly

Just use a tape to increase the friction, i managed to open mine here (WTS) Nichia 219B R9080 sw45k & 219C 5000k R9050 - #6 by AnhTran

Oh, good idea, I will try it, thanks!

Does the bezel come out easily? It just screws out from the front by pressing against it with some friction? Or is there some glue to soften?
Just got one of these in the mail and there are lots of dust behind the glass

Hi,

Mine had no glue.
Yes, pressing down on a slab of rubber and twist.
I used a bicycle tire inner tube.
Posts above yours mention tape.

I’m sorry i hadn’t read your post earlier.
Now it’s more than 8 months later…
And also, i don’t really remember how i got the old LED off…
It was damaged and i think it came off with a little force, but maybe i put a soldering iron on it…

No glue at all, just friction.
I used self-adhesive masking tape to screw it.

Be careful, there’s no centering washer in the lamp, it is a little difficult to tighten the bezel back with proper emitter centering.

mine does have a centring gasket.
It’s in the bottom left corner of the 2nd picture in the OP.

Yes, that’s a gasket but it’s not centering. It does not guide the reflector from the side when it is screwed down.

Mine is a centring gasket.
It has a raised outer rim that fits around the reflector base.
Maybe they /you put yours in upside down by accident?
Maybe you have a different one.

It’s the best AAA light i have.
Definitely the brightest too.
