An offtopic expert question: dear Vinh, do you use an oscilloscope in your work and if yes, which one? :)

I will answer this one over at the lounge. Thanks

I got this budget Infared Thermometer on Amazon for number 5 heat test. Seems off. For example my wall seem colder than 72F and, my skin less warm than 88F, a metal surface I heated up that is burning to the hand was only 200F, icecream in the freezer at a low 17F. I guess worst case we will just use it as a guidance on temp changes rather than accuracy. Anyone got one to comment?

#9...start with bird shot, and keep ramping up the caliber. Know anyone with a .50 cal? No matter what the #9 test is, for the most drama, it could be shot at night, only lit by a dozen or so other Genesis lights...

By the way its crazy how much adrenaline I went through. Doesn't seem much on video but I was crazy nervous and excited. Off camera we did a test run over a "normal" light and yeah it was crushed. That made me soooo worried!

I was thinking if the head got crush then I will be VERY screwed! I wouldn't know what to do. Literal devastation. I am so happy we made it this far. In fact I couldn't sleep more than 4 hours last night thinking about everything and what's next. Whooo :)

Crap shop just made a correction. Testing sample Proto V3 is 6061 not 2011. Even softer! Yikes!!!

He does confidently thinks that 7075 can actually take a 9mm. He said even .327Mag is OK! I don't think so.

Now I cant afford to beat on another light but if anyone has interest in shooting one may be we can pitch in for a 7075 beat down when its in. Would be exciting!

These torture test are exciting and fun to watch. And I could totally see your heart pumping in these videos. Especially in the vehicle run overs. Keep it up.

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. :grin2:

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! :thumbsup:

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

Machined engraving help preserved the marks that laser engraving otherwise wouldn't :)

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:

Free Tange V2.1 in your choice of color for top 2 closest guess.

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!!!!
