Run #3 is available now! Check out my site for current availability.
Some of you will notice that I increased my prices by $25 on each light. After getting about 150 lights into this process I'm realizing I can't keep doing the "fancy" surface finishes I've been doing and deliver more than 20-30 lights per month. So, I increased the price a little bit to make it so I can pay my rent and electrical bills at that volume. Still not making much to put in my pocket. This month I made 60 lights in one batch and, while it's possible, I don't have any time to work on custom orders or new stuff like my 80K lux Alpha lego head or my AA QTC light.
So, I've been working with a local machine shop to develop the "Alpha Production" flashlight. It will be mechanically identical to the custom Alphas...same components, same dimensions, same nickel finish...but it will be machined my someone else (not me) and the actual surface will be plated "as machined" instead of being stone washed, brushed, blasted, or polished. I will still hand assemble every one.
Back to the price increase. My current Alpha Customs have increased to $225. The Alpha Production comes online, it will come back in at the $200 price point. CPF members will be able to choose their Alpha Production LED; regular website customers will not.
SPECIFICATIONS: (all styles are mechanically identical)
This light is designed for a single 18650. The driver can handle up to 6V, but the driver itself will get REALLY hot when using primaries, regardless of the power setting used. The driver WILL NOT run on 2xRCR123's...you will fry it. The XML and MCE can operate on low and medium with 123 primaries, but the current draw on high will be excessive, cause heating, and possibly catastrophic failure of the battery. In general, I DO NOT recommend primaries for these lights if you want the best and most trouble free performance. Stick to 1x18650.
MCE/XML Driver: Shiningbeam 2.8A CC (3 mode)(2.8V-6V)(100%=2.8A,30%=1A,5%=.14A)
XPG/XRE Driver: Shiningbeam 1.4A CC (3 mode)(2.8V-6V)(100%=1.4A,30%=.44A,5%=.06A)
Reflector: Ledil Boom SS (Smooth Spot, FWHM 10°)
Window: UCL glass 2 side AR coated
MCE Run time: 1.5 hours on high (measured)(XML & XPG not tested yet)
Now (for $5.00) I will hand color your Ti clip with a torch flame. This produces the same oxide layer as "Ti Anodizing" but it's accomplished by heating the metal. Every clip looks different and is an individual work in it's own right. Oh, and it looks awesome.
Jason in your futur design you should try to get the head resting flush with the body or the battery tube. a bit like the Mac's Customs design. The idea is not to have anymore this abrupt steep at the transition head/body to smoothly pass on to the other part of the light without notifying the change of part when you visually go from top to bottom of the light.
I don't know if I made me understand and if I got my idea through, may be it is worth investigating this design evolution
Can we look forward to your AA QTC light in 2012? Happy New Year!
I hope so I'm starting to give this some serious thought. Problem is...I can do a direct drive with lithium ion, but I suspect most people will want to run alkaline AA's as well and I need to find a small diameter single mode driver. Haven't found one yet so any hints would be appreciated!
Not just a small-diameter single-mode driver, but one that responds to varying resistance on the input side by varying the output to the LED. I'm not sure such a driver is possible. On the other hand, a piece of QTC material could be sandwiched between two circuit boards and compressed when the battery presses against the postive contact. The QTC material could then act as the current-sensing resistor to govern the output of the driver, instead of using the QTC material on the input side like Peak does.
Actually, definitely do the second one. That idea is much better now that I think about it.

Sounds good but not exactly clear what you mean. Could you explain a little more? Also, what battery are you thinking about for this setup? I'd love to be able to do a li-ion only version but methinks the troops might rebel
