Oh boy, I hope this is not becoming another flashlight design fiasco… it´s not rocket science to make a clean und secure flashlight and driver design, no?

The dielectric layer is normally pretty though and doesn’t wear too easily even with the tightened screws, but if that becomes a problem they could simply reverse the polarity and reflow the LED the other way around, so if it shorts it will only lose modes and not become dangerous. Another fix would be if they used anodized screws and a plastic washer disk on top.

It’s just a light folks. Chill.
Nothing that can’t be adjusted. If the screws bother you, remove them. Just put some Arctic silver thermal paste (not epoxy) under the mcpcb. The pressure of the optic on the mcpcb from the optic, once it’s tightened down is more than adequate. I doubt it makes much difference any way you look at it.
Four nichias with a 16350 are only going to put out what they can.
I build a lot of DD 14500 triple XPE2s, and the tail current never varies between 4.2A and 4.5A no matter what’s done or what batteries, protected or unprotected. It is what it is.

Fool me once, shame on you. Fool me twice, shame on me. I have no one to blame but myself ( and manker).

Sharpie is asking some important questions.

It really looks like the outer area of that MCPCB is all positive. If that’s the case it’s a bad design and a quite dangerous one. Could be fixed with isolation discs under the screws, but there isn’t even enough space for the screw’s heads…

Another good question: what’s the current draw? Lumen numbers are lower than I expected. I’m getting about the same numbers with three 219B-V1 and 5A regulated driver (stacked 105C)…

And I have one more question: Kenjii wrote that there’s a front glas on top of the optic. How many O-rings are there and where are they placed?

Hi,

there are two O-Rings. One on the threads of the pill and one between bezel and the glass.

Here are some closeups.

I got the screws out now. The replaced screws have a slightly smaller head and fit without touching the pill.

Regards

Kenjii

Thanks Kenjii, right amount of o-rings at the right spots, that’s good news. EDIT: Oh boy, I think I read what I wanted to read…BUT:no o-ring between optic and glas?How is the optic kept in place? Does the glas make direct contact with the optic?

Well, positive trace goes almost to the edge, they should’ve kept a bigger distance from where the screws go at least.

The smaller screws look like a better fit, but based on those closeups it does seem the + side is right under the screw head… as long as that solder mask holds up it would be OK, but that is still rather poor. All it would take is for as screw to be put in crooked or a screw with a rough underside to the head to cut through the mask and create a short!

Ok, now there just was a short on the side where the messed up screw sat…. so i know why that screw was not screwed in completely.

I think screws were never a consideration in designing that MCPCB. Usually you have optics with 4 legs and the better way, IMHO, is to have the pins a bit longer to protrude past the MCPCB into holes in the shelf locking everything in place and preventing rotation.

So that’s a unit they send to someone to do a review. I think I’ll pass.

The joy of getting my shipping notice this morning quickly evaporated…

Will the light still be safe to use as long as one uses a protected battery?

There are always ways to work around that kind of issues, but I think we all would prefer not having to go those ways.

Hi,

i think this is a preproduction sample …

New ceiling bounce (30 sec.)
Efest Purple IMR 1537 Lumens
AW IMR 1382 Lumens
Tensai/Enerzig IMR 1696 Lumens.

That new battery from Tensai is great. Lumens went down much slower.
Regards

Could be QC is part of the reason for price differential between Manker and Astrolux versions. I’d be curious to see inside of Manker version to see what else is changed besides driver.

Hey guys - I´m back from the cave playing with the Astrolux S41 cool

( its 1:40 am - video and pix follow tomorrow)

 

some thoughts about my sample (nichia LED)

  • WOW - nice and small
  • good build quality, no dings and scratches
  • smaller than short BLF A6
  • head diameter is 22 mm
  • build order: bezel - Oring - AR coated thin Lens - quad optic - Oring on the head - massive copper head 
  • no extra isolation disc between screws (a bit too big imho) and the copper MCPCB
  • LED wires are 22AWG
  • MCPCB has a direct thermal path
  • driver retaining ring was a bit loose and unscrewed with the tube (that was tight)
  • driver IS the BLF A6 (with 4/7 modes + discos)
  • nice tint
  • better beam than my triple A6 (XP-L HI)
  • much lower low than my  triple A6
  • switch PCB is the illuminated design, but not populated
  • double springs in tailcap to reduce resistance

 

some quick&dirty numb3rs (as shown on the luxmeter, usually 10-15%  high)

S41 2450 Lm 12 A PS 4,1 V
  1520 Lm 5,6 A IMR18350
  2100 Lm 9,2 A 30Q
       
BLF A6 3D  bridged 1700 Lm 5,6 A PS 4,1 V
A6 (3x XP-L HI) bridged 3250 Lm 10,1A PS 4,1 V
Astrolux SS  stock 1450 Lm 4,4 A PS 4,1 V
EC11 940 Lm 2,8 A IMR18350

Powersupply was set to 4,1V (its a 30V/20A PS)

other lights to compare (my lightbox is not good)

 

more asap

 

good night my friends! Wink

Hi,

as you can see in this image, the screw on the right is not screwed in completly. It won´t ever, because both screws are stuck at the sides of the copper pill and the head of the right one is already messed up. These should have been placed a little bit more to the center. The MCPCB seems to have a good connection to the pill even with only one screw but i think it is much work to get this screw out. So changing the MCPCB will not be as easy as expected in this light.

I like the beam the optics produces. Pretty similar to the popular 10507 with a little bit more spill.

Regards

Kenjii


it won’t cause short out.

These two screws are isolated from circuit wire which also called MCPCB board so that should not cause a shot circuit even when the screws got contact with the body.

Is that as safe as what you both (Banggood & Manker) delivered to us with the UNSAFE Cometa lights?
Specifically your pill design & implementation?

I’m not much of a solderer, but can someone comment on those + and – solder joints. On a scale from 1-10?
