Sky Lumen Nguyen Flashlight

Keep in mind max (discharge) operating temp for the battery is 80C and recommended is <60C. Hard to say how hot the battery was while doing this, maybe not 80C since you were outdoors but I am surprised it lived.

Yes the test went beyond all safety recommendations to prove the robustness of the light circuitry.

In practice with accordance to Sky Lumen Purchase Agreement all lights temperature should be monitor with bare hands and must be turned down several level or OFF once the light reach the “Too Hot To Hold” temperature. In this specific case, 2.5min was is the recommended time to throttle back.

In hindsight, the light forwards switch code name FS54 is especially impressive considering the circumstances.

I know…I was just making a joke haha

But you know If SLN survive 9mm which I dont think it will hahaha We might have to break out the S&W 500 just for KICKS!

I don’t laugh very easily, but I was laughing my butt off watching this!

Watching the video make me want to say. Get the hell out. I will show you how its done. hahahaha

Look at these Bullet comparisons —- In the video they’re shooting the T-Rex—- 750 grain 2480 ft lbs / sec with 10,180 ft lbs of force Elephant Gun

WOW! How many amps for that output? Very impressive build, Surefire only through theirs in a dryer.

I like this flashlight a lot. Hope the price will not be too high.

Unfortunately it is too high :frowning:

I cant get around that unless have it made in China.

:wink:

at least Vinh is honest :wink:

Finally we can get a true 10k+ lumen single cell 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.
