Sky Lumen Nguyen Flashlight

I would be VERY surprised if it could stand up to 9mm. LockPickingLawyer and BosnianBill recently shot a bunch of locks and InRangeTV has been doing AR500 armor penetration testing.

SLN Test 8: Subzero

SLN Test 9: Boiling Point

SLN Test 10: @ Depth

Your excitement is contagious! Congratulations on passing the deep water penetration test! :+1:

That was my fav test video to date. Gave me a tear or two from watching you as happy as you were.
Congrats Vinh!
and that’s not even a diving version! The drop test is my most anticipated video. Can’t wait.

Thank you for all the support! I dearly appreciate it. First step to everything is usually the hardest.

The drop test is schedule for tomorrow. We will do the drop test with the unpotted light engine that we have been using for all the tests so far. If it pass then wonderful. If the light engine fails then I will make another light engine that is potted and redo. Potting will be optional at time of order. I suspect most will not need this option as it adds little benefits if our current light engine passes all the drop tests.

Today after the “@ Deapth” test I found out the optics seems to be a bit bent from heat. I am sure the “Boiling Point” test did this because I did not notice this before that test. Beam is still good and light of course operated flawlessly but I thought I mention that. If you are going to cook the light without a battery inside then the optics is the weakest link.

Can guarantee you this light will be $300+

If we buy it from you? :slight_smile:

This is basically a custom Made-in-the-USA light in very limited quantities. Given the manufacturing cost here and the amount of time and effort spent developing and testing this light, even at $300, I don’t see how it is profitable, but it is a good start and is probably the 1st USA made light geared toward flashlight enthusiasts so I will definitely buy one to give my support. Hopefully the 12-emitter version won’t be too much more expensive than the others. :wink: I will probably supply my own emitters

Would be interesting to submit say a convoy S2 or an other reasonably priced tube light to the same test at the same time to have a baseline and validate the design choices.

I remember some years back at CPF people were suspecting a particular light with very thin walls would be fragile, someone torture tested it in like manner and it passed with flying colors.

Not much I can do about the host price. I am lucky Larry help with the drawings all for FREE. Otherwise I wouldn’t make a single dime on it if not acatully lose money. The light engine is where I am hoping to make the profit. However I will make them as affordable as I possible can especially the 12 LEDs one since that is one I want as many people to have. Just looking at it would be a joy. The good news is you only have to purchase the host once. It should last a lifetime and upgrades down the road wont be too pricey. Future lego parts are also in the planning to make the light suitable for even more audiences. Also if the light is made from 2011 we might be able to drop the price may be $50. If we go 6061 may be a bit more…But I suspect once we have 7075 in hand it might be worth it just to go all out with this metal. I cant wait to get my hands on it.

I ran over a light which I wont name and it didnt hold up the first run over asphalt with the truck. I decided not make a video on it as putting down another brand isn’t my intention. I am not trying to display what other brand lights cant do. I simply want to shows what mines can. Other brand lights will do many many things mine can’t. They night not pass all my 12 tests so far but they might pass other tests that are more crucial to the decision such as looks and functions that mine will not provide. As a light enthusiast, I honestly treasure and enjoy them all (except for *Fire clones). No point is putting down another to validate my design choices.

The toughest test was likely the “@ depth” and the “Drag It”. I suspect most of my other lights will not pass those tests. Yet, I know mines will not pass the tests that those lights will have for mine…

I see.

For reference i found the thread mentioned here , pretty impressive for a thin walled multi battery light.

Seems the Fenix store themselves used these as marketing technique.

Are you saying that the light engines can be swapped like P60?

Yes. The user can swap light engines anytime they want. Future upgrades to the light engine or to replace with a new one is a breeze.

I watched all the tests and I was impressed. However, JamesB is right: how can I know if other lights would pass the same tests? Also Acebeam, Thrunite, Zebralight, etc. produce lights that seem very robust and resistant. Without the possibility of comparations I can only say that this light is really reliable and of excellent quality and that I would buy it without any doubts. But I cannot say with absolute certainty that it is better than the others lights. On the other hand, this was not Vinh’s intention.

I’m curious how the light engines connect to the host? Is it threaded in? Any pics? I hope the heat transfer will be much better than the P60 that has a big air gap between the pill and the host. Also any chance of copper pills for better heat transfer?

I will have details before launch but as you can see from my Heat Test 2 heat is transfer very well. Light heat up instantly & the readings climb instantly. This is also evident by the 4000L Quad White 2 LED set up indicating that there is very good electrical contacts as well. Multi emitter light engines are solid copper. 12LED light engine gets the most copper…

I don’t think this is 100% MADE IN USA!! I see other pictures of light and you used made in China parts

Not to mention you are using mtnelectronics as a supplier for this light and we all know that mtnelectonic is using made in China electronics!!

I think it’s better to buy Oveready Boss than this one because Oveready Boss is 100% made in USA and Russia and the quality of Oveready is above and beyond anything else in the market

not to mention you are going to ask ridiculous amount of money for it !!!!

It’s not worth it at all

Just think about it for a second if he takes 150-200$ for a light that cost 20$ shipped for just changing the led!!??

how much this one will cost and you know it’s not 100% made in USA

It’s better to be safe than sorry..
