Astrolux S41 - presale ended

Mine shipped too.
Hopefully won’t go south like the Cometa

Also mine was shipped 4 hours ago.

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.

I ain’t too excited. If it’s crap, it’s still a win! I’ll get po’d and quit buying……yeah rite!

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

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.

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.

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.

What kind of battery,18650 or not?

All 18350. I have no 18650 battery tube.
