ALIVE: Astrolux S42 groupbuy: US$ 25.95

Given how the UI sounds on paper, and its curious similarities to the BLF-A6, I hope nobody thinks I had anything to do with the S42. That would be super embarrassing.

Astrolux S42

What you thought you were getting…

What you actually got:

I believe the D4 will be very mod friendly.

Sorry I don’t know my flashlights. From which manufacturer?

Well the BangGood listing of the tube here: https://www.banggood.com/Astrolux-S41-Astrolux-S1 says "BLF A6" right in the heading and description, so you are saying it's not for the BLF A6?

I just thought the BLF A6 tube maybe changed since the beginning?

It is an intl-outdoor design, the brand name is still unknown (not Noctigon), Hank announced the D4 here.

In my case that's what you HAD to do to make it work.

The front end of the battery tube never reaches the contact ring on the driver board, so it's open circuit even fully screwed in. I proved this by screwing in the battery tube backward, so that the longer tailcap threads can actually reach the driver board. It would appear that the driver board is glued in place about 2mm too far forward, out of reach. That applies to the short battery tube for the S1/S41 as well as the 18650 battery tube.

The only way I was able to get any life out of it, using ANY battery or tube, was to make a circular shim from a coiled paperclip and wedge it between the driver board and the front rim of the battery tube. This solves the length problem (crushed batteries) as well as the open circuit in the front. My only concern is that the shim might eventually migrate inwards, risking a short circuit if it touches the positive spring in the center of the driver board.

I have contacted Banggood twice about this, using this explanation, and am awaiting a response.

Thanks. It looks fairly similar to the FW3A, but with the switch on the side. Coming from Hank, I’m guessing it’ll be pretty nice. I wonder what the driver and UI will be like.

Yep, it’s not gonna fit in the A6.
It will fit the S1 and the S41S. Your A6 tube has a loose fit in the S42, doesn’t it?
And i’m sure the S42 tube will not fit in the A6
But they mess up the short tubes too…
You order a S1 tube and you may well get a A6 tube or vice versa…

Thanks for this info!!

is the driver 17mm diameter? maybe we could swap it for the mtn fet driver

It’s 20mm (maybe 21mm) driver:

IF the light lights up - how is the output on turbo!?

Well we could use a 17 to 20mm adapter ring

But I really hope there is a way to flash another firmware to the stock driver

Well, I haven’t received mine yet; but it sure sounds like BangGood have made a real mess of this.

The only way I can think of to solve the problem, that all customers can apply without help, is if BangGood distributed new battery tubes of a dimension that works with the other components to all customers (without us having to go through the third degree with customer service).

Maybe M4d M4x could have a word with Swi?

That output seems ok , it seems good for really close range flood …but that’s if you can get it to turbo … I should of spent more time reading the manual or watch a YouTube video… because it’s like a puzzle trying to get it on then to turbo …I’m probably missing something but it’s so weird…If there’s a way to make it off and on only turbo I would do it

I’ve tested the USB charging on the S42. It was able to charge the 18350 battery in it, but when it’s fully changed, the battery level indicator shows 4 blinks, not a full battery 5 blinks. The battery is a new KeepPower IMR battery. I am not home so I didn’t have a chance to test the battery with a multimeter. But it seems that either the battery isn’t fully charged by the flashlight, or the battery level indicator function on the flashlight isn’t accurate.

In 7 mode set, click to moon then press&hold - turbo comes on. It's right there in the manual. Some funky stuff - dbl-click toggles between 7 modes and 4 modes, press&hold when OFF goes into lockout and turns off the dragon's breath. Didn't check parasitic drain, but interesting what it is with the dragon's breath running.

Thanks I was trying to read it before work but now i get it … dragons breath that’s some fancy stuff lol

Hey my friends!

Astrolux told me they noticed that some customers did not like the rubber covers.

so they came up with a version that sits tighter in its place:

The new design will be mounted on the next batch of lights.

AND it can be ordered for free if you bought an Astrolux S42 already
(procedure to be announced when stock arrived)

Could they possibly include one with what ever fix they come up with for the battery tube? Thats the big issue for me, I dont want to have to tear into this light and mod it right out of the box

Edit: I didnt notice the “for free” after “AND it can be ordered” lol
