Almost nothing is 100% made in any single country these days. Even Chinese brands like Huawei and OnePlus have components from USA, Korea, Japan, UK, etc. Skylumen is a USA brand and this light is 100% USA design and almost entirely USA made with maybe a few parts from China and this to me makes it special enough. Also made in China does not mean it’s bad. Apple products are made in China yet it’s quality and reliability is second to none. Even Samsung and Sony can’t come close to Apple products in reliability. Some cheapo low tier Chinese manufacturers gives China manufacturing a bad rep but as the saying goes, you get what you pay for. Use a larger and more reputable shop in China and you get quality to match. Tim Cook said the reason Apple can’t move manufacturing away from China is the skill, precision, and quality of manufacturing China provides. So if the right parts and chosen whether it comes from the USA or China, and Vinh thoroughly tested it, I see no reason to doubt the quality of this light will be top notch.

I find it funny everyone suddenly is against China-made lights and all pro USA-made lights like they’re some kind of easily-impressionable 14-year old girl that hoo-has off of who yells the loudest on Twitter. It’s like they think the location of the CNC-machine makes a difference in the quality or some mysterious aspect of the product.
Guys remember this this forum is not possible if not for China. China literally made ALL, 100% of the lights people talk about these days on the forum. You can find some shitty lights made in the US like maglites but it’s an embarrassment and a non-factor in terms of lights. All of the popular brands like Astrolux, Emisar, FF, Olight, Acebeam, Imalent, etc, etc are all Chinese brands.

Even Vinh makes a killing off of modifying those China-made lights. Imagine him trying to make a living if he didn’t have those base lights at- or near-cost to buy, instead had to pay retail for USA made lights lmfao.

If this light has made-in-China components then I’ll probably splurge and buy one of these lights. I make a point in my life to support those poor but extremely hard working individuals in China working so that we may have access to modern life-changing electronics at such affordable prices. If it weren’t for them all of our day-to-day items would cost manifolds over what they cost now. For example I just bought 8 of the Astrolux MF01 mini and will give 6 away to friends. For $44 it’s an insane, mind-boggling deal for how good of the light this is. Granted I haven’t got the light in my hands but if the MF01s is any indication it’s an exorbitant light wonderfully crafted to perfection at a killer price point.

Lights like the MF01s made in the USA (not that it’s possible, for we’re used to seeing junk 1500 lumen lights w/ ugly tints in our brick and mortars) would be $300+

Notwithstanding top-tier Chinese lights like Acebeam is getting their price-point up there but I don’t buy their products.

This thread is to present and discuss Vinh/Skylumen project!
If you people wanna rant and discuss anything else, create a thread and do it there! Leave this thread for what it is supposed to!
Let’s not make sb lock this thread due to parallel discussions and unpleasant exchange of unnecessary arguments!
Shall we move on, gents? Hat

That’s completely untrue. I don’t think you looked at the whole thread or his videos. This is a completely new light being launched by Vinh.

Have you ever looked at the prices for PFlexPro semi-customs?

I don’t buy your argument on some components being sourced from outside the US meaning “not made in US” either. Cells phones have much of their electronics manufactured in Korea or Japan and yet are listed as “Made in China” as that is where final assembly happens.

Is there evidence that Overready sources only US-maunfactured for Every. Single. Component. in their lights? The boards are custom AFAIK, but where do you think the chips, wiring, etc. are made?

Vinh, what size is your 12 emitter board? Will you be using it in your flashlight mods? Will you sell those separately to modders?

About 23.8mm
A special light engine is in design just for this custom MCPCB to be used in SLN
I might use it in other lights as well
I might ask Richard to help me sell some as I don’t sell parts to avoid stepping on his toes
Nothing is decided yet and the MCPCB and copper light engine for it is still in design

The impact & drag test on the same day put dens just like that on another cell.

The 4 story hit must he HARD because it put similar dents with just 2 hits.

IMHO you can avoid batteries looking like that by separating the connected-at-all-times aspect of the spring from the absorb-the-total-impact aspect.
Absorb the impact by, let’s say, a fat soft rubber cylinder shaped ring around the spring.
That way the fully compressed spring does not have to behave like a steel nail.
The soft ring can deal with unbelievable forces, because it is surrounded by a massive tube.

Just saying. The spring only has to deliver the juice. Give it some body guards.
But maybe you already have thought of that and I’m only kicking in an open door (Dutch expression).

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

I modded a Hounddog or something like that sometime ago and I remember this light was excellent in build quality and design. This is my debut light with simple designs which is not on the level of any major brand.

Yes, Vinh, this is a good idea. Malkoff, for example, sells thick o-rings to be placed around the springs, known as “battery bumpers.” The idea has been discussed before, on the other flashlight forum (search for battery bumper), and perhaps here on BLF, as well. These bumpers are often a simple user add-on, using various common o-rings. Back in the 2000’s, Peak used to accomplish the same thing with neoprene “donuts” glued in place.

Looing forward to the SLN!

I will look into finding a good fit bumper disc.

EDC only if this is ur duty/work light. It’s too big n heavy for a light u keep in your front pocket just for emergency. There r way better lights for that.

Vinh,

Been a bit, appears you’ve been quite busy!

I played catch-up on this thread today, and quite enjoyed it. Your destructive testing and the lights persistence to continue working is nothing short of amazing, what a BEAST of a light. If you can think of a test using our waterjets, I’d be happy to accommodate anytime.

So well done man. Your enthusiasm and passion for this project is infectious, truly inspiring. I’m definitely interested in the finished product, especially knowing your Lego intentions down the line. Good luck on your remaining steps and hope to talk soon.

Thanks for the offer! I might take you up on it. I am not familiar with waterjets and how one would carry out such test. May be you can send me a quick email so we can keep in touch?

A friend suggested that I should put it in the washer but I am not sure how to do this without putting a ton of dents on my washer…Mom would whoop my ass. We already knwo the light pass the drag and drop tests so may be I can just wrap it around a tank top…Not sure if this is worthwhile…

Wow! Just WOW!
I like that you built this light as a tank with that quad optic. Separately I got completely the same idea as Henk4U2 as I saw the battery dents. But then saw he was faster Big Smile
Keep up the good work and maybe I will never own one of your built lights because I can’t afford but I like to get inspiration from your mods to my mods but make it a little different.
Have a nice day!

Hey Vinh, right now I just don't need another flashlight, but after viewing all your torture videos, this will be the next one I will be saving for.  You went through a lot of effort to prove just how tough a light it is and to me it would have to be the ultimate survival light, thanks man!
