New blog posts now online regarding potted electronics. It is hard to overstate how critical potted electronics are for extreme durability. Link to written blog: http://www.ELZETTA.com/blog/potted-electronics/ Complementary video blog:  |

Quoted: I have potted quite a few cheap p60 moduals for weapon lights. The process is actually pretty simple. Yes, potting is a simple process yet no other major flashlight manufacturer is willing to invest the time to do it. The increased durability it provides cannot be overstated. |

Interesting, are you saying that surefire does not pott their moduals? I wouldn't know, I just figured sure fires were potted. |

Interesting, are you saying that surefire does not pott their moduals? I wouldn't know, I just figured sure fires were potted. I am unsure if SF modules are potted or not, but we know for a fact they are durable. I have seen VERY FEW Malkoff's die, and VERY FEW Surefire LED's die, even when cruising the internet, where everything dead WILL turn up, it seems. that said, let's look at run-time vs. output graphs. Here is the SF E2D Ultra, a 500 lumen light with flat regulation: 
Here is the Elzetta Bravo, a 650 lumen light with flat regulation: 
Pay attention to the comparison of CR123 primaries, as this is what you will use when the chips are down and the light NEEDS to work. You can see the thermal management paying big dividends with the Elzetta. I love Surefire, and I love Gene Malkoff/Elzetta. All 3 are GREAT companies/people to do business with, and I'd give any of them my money---and have, in the past. Let's compare the E2DL (200 lumens, although I've seen IS readings as high as 210 OTF), and the Malkoff M61: 
It's plain to see that the thermal potting DOES help maintain more consistant LED temps/output, and likely leads to a longer theoretical life. I say theoretical, because I doubt anyone "uses" their LED flashlight "to death". If so, please, let me know, I'll buy stock in your preferred CR123 manufacturer. I have read of people killing the SF Fury's mounted near the muzzle of a weapon, though. However, the SCOUT model lights can live in muzzle blast just fine. I have never heard of one dying. SF has excellent shock resistant qualities built into their weapon lights which need it. I also prefer Surefire's TIR. It is made of a CoC polymer and is much tougher than the Polycarbonate units out there. That said, I have never seen anything that can compared to the potting job that Malkoff (and now EDC+) are doing. It's simply the most durable way to preserve the guts of those modules, and thermal management is a huge benefit of it on the side, or maybe it's the other way around, depending on how you plan to use the light. |

Speaking of durability, is it possible to damage the tail cap click button by pushing it until it is completely flush with the back of the aluminum tail cap? As in what would happen if the light was dropped a long distance and impacted in a vertical orientation with the tail cap down? Or if you struck the tail of the light squarely and hard against a hard object?
If you could drive a nail with the center of the clicky tail cap, now that would REALLY impress me! Given the rubber would almost certainly tear, but if the guts could hold up, wow. |

I'm surprised someone hasn't copied y'all on this yet. |
