That is true.^
Had to replace my QTC right out of the box. Kind of annoying, but I understand those things happen. I have HORRIBLE luck with flashlights anyway. This makes my last 5 flashlights (all new from factory) in need of repair... straight out of the box...
BUT! luckily, Veleno Designs was great with CS and made it an easy communication process. When the replacement came it... it took <2mins to replace.
Works like a charm now! All I need is trits now!
Finally got it! This thing is small. Waiting for the battery to charge to check it out. Awesome little keychain light.
Sent from Sky net.
There is something wrong with my Quantum and I think it's the QTC. Sometimes it's very dim with a freshly charged battery and I feel like the battery dies quickly. I looked up in it and the little dark grey blob right behind the LED is all messed up.. I'm having some bad edc luck lately.
Yeah that would be the QTC.The good news is they are cheap and easy to replace.I also had a battery where the top plastic sat a little to high and didn't allow for full engagement of the QTC.There is not to many things that can go wrong with these lights and it's one of the reasons I love the design.
I think someone mentioned earlier that running two QTC helps with operation but I haven't tried it so I can't confirm.
Thanks! I emailed Steve and asked him about getting another
I had the same problem. I replaced my QTC yesterday. They're like $4 shipped for a replacement. And easy to replace.
It ships from Taiwan but it's pretty quick.
I'd recommend using Victorinox tweezers to get it out. It literally takes 2 minutes to open the package and replace the QTC.

My D2 QTC tab is starting to produce a little powder inside the body, but rather than replace it once it's fully disintegrated, what conductive spacer would be best? I think I'd rather have it come on at full power anyways.
I use a small magnet.
Cool...that seems easy enough.
Now I am not sure if I should just do it now or really wait for the QTC tab to fully disintegrate.
I'd totally buy another quantum if the forum store had a titanium!
Just installed the new QTC last week and the one is already busted up.. Am I doing something wrong?

FYI, I saw a titanium 38DD with a blue and purple adonize and trits over at CPF marketplace. It's basically the precursor to the 40DD and Quantum DD.
Two things come to mind 1) Make sure the QTC is centred and 2) When going to max brightness don't crank it too tight.
I think magnetic rings are probably best for infinitely variable lights. I wonder if one could be built into a light this small.
Nope. There isn't even room for a driver. No clue why a mag ring would be an improvement. Less flicker for more complexity/cost, output inefficiency, and some parasitic drain.
I have 2 years on the original QTC of my 40DD.
Got mine yesterday and love it.

You know, after having mine for a week or so, I think I'm going to flip it. It's an awesome little light, but I find myself always wondering how much juice is left since the battery is so small. I ordered an extra battery, but it seems to be DOA, so I just have the one.
It's an impressive amount of light for the package size, and I did actually have to use it when the power went out, but it was only to go get my primary out of the bag.
I've gone back to my AAA lumentop stainless worm on the keychain since I relegated the tool-pouch to my murse.
