Thread: Sky Lumen Nguyen Flashlight Torture Tests Videos

    Wow, you really are trying hard! Doing a burn-out over it parallel was bad enough, and even though 6061 is soft, the hard ano was enough to protect it, and you didn't scratch the ano! Perpendicular was asking too much for the 6061, it's just too soft. 7075 would have had problems as well, but the scratches would have been much more minor, it's MUCH harder than 6061. Other than some of the other really expensive lights made by small makers like us the lights are 6061 or sometimes 2011. The main advantage of 6061 is corrosion resistance, which is why it's used in aircraft, but it's soft and lower in strength than either 2011 or 7075. 7075 is getting up close to steel in its characteristics, but is VERY expensive, which is why it's not used in many if any high production flashlights. As long as the flashlight is anodized and/or alodyned, corrosion resistance isn't an issue.

    Since you seem bent on destroying it, you should really keep going after you hit it with your high powered pellet rifle. I'd go for 22, then 308 and 9mm. Even though it's 6061, it's strong enough that I wouldn't be surprised if it gets as far as the 9mm. Who knows, it might even handle the 9mm. I'm pretty confident that the 7075 will survive a 9mm if you don't hold it fixed solidly, and who knows, it might even survive that. If you had had the 6061 versizn glued down to the asphalt strongly enough to keep it from detaching during Phuong's burn-out, I doubt very much that the hard ano would have been fazed.

    Wow I didn't know 7075 was that much more expensive and tough. Makes me like my ROT66 even more.

    Yes, and this light has a LOT of it!

    You should put a link to this thread in the last post of the old thread. Some of us might get lost on the trip otherwise :P

    Wow! , I just saw your videos last night and Genesis did very well all things considered. You have already surpassed the level of destructive testing offered by run4jc, over at the famous Saw Mill Inn. I can't wait to see how the light performs on the final tests. Zandar

    I just perform the heat test and the results were extremely surprising. While video is uploading give me a guess on the following values:

    • Ambient temperature 67F
    • Light engine Quad White2 + VN4 with thermal protection disabled.
    • Manker 4800mAh 21700 tested cell
    • 2500L at 30s



    Time in Min until “too hot to hold”:
    Time in Min until peak temp reached:
    Can circuitry handle heat nonstop?
    Max start up lumen:
    Test ending lumen:

    Our man has finally spoken! Mr. Larry is the man behind all of the computer design. On our road trip to Cali last summer Phuong and I met up with Mr. Larry and his wife for dinner to thank him for a huge purchase that he made to help me acquire my engagement ring for Phuong. Some of you might have remember that the sale close prematurely as be bought all of the lights from the sale to help me out. During dinner Larry proposed that its finally time I should build my first light. He volunteered his time and expertise with computer design and machining FREE OF CHARGE! We got SLN today 50% due to Mr. Larry! I likely contributed 10% to the left over 50%. :-P

    A dear gratitude to the man that have done everything for us without ever asking for anything in return. The man that has put up with my countless request for changes in design and unreasonable requests. The man that made all my talk happened. Thank You!!!!

    But first may be I can send you the current 6061 sample to be shot at? Do you think you can help us make a video?

    I can also shoot and record if help is needed. I have at least a dozen pistol calibers and a dozen rifle calibers and access to hundreds of others. Just my opinion but I don't think rifle calibers will be helpful or necessary. It would be fun to see .22, .380, .38spl, 9x19, .45, and then whatever it takes to make it stop working. I think one hit on the head with 10mm or .357 would cause enough deformation and perhaps shock to disable it.

    Shots should be center mass where its strongest. If the light survive from the shock then its already too impressive. I personally don't think it can handle 9mm but I haven't handled 7075 either.

    If it's 7075 hitting slightly off center where it curves away then I can see a 9mm bouncing off it.

    That sounds wise and consistent and I'm guessing that's where the thickest part of the light is?

    Based off all the mild steel plate of various gauges I've shot at over the years, I don't think 115gr 9mm @ 1125fps will cause deformation. A 115gr 9x21 or .38 Super @ 1450fps... probably a different story. Failure from shock though, I have no idea. I don't know what typically fails first from shock on a flashlight.

    For sure. Bounce/sheer/deflect into a spray of fragments. Even square on I think the 9mm will lose most of its mass to fragments. It will be neat to see what Scout comes up with.
