Not even …I don’t think any type of aluminum can handle any type of rifle round. Pistol caliber is one thing. Rifle round is a whole new animal. I shoot .223 green tip through 1/4” mild steel like butter.

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 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.

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.

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
