Wow. That looks so absurd. It must be super bright. =) Amazing!

What the crap, Dirk.........!!!??!!
I just fainted......
Thanks guys, it means a lot.
Don't want to change gears on you as Dirk's build is worth some attention, it turned out very well if I may say as much... that said, also want to mention the recent 'Legolas' build for Crenshaw...
A while back Crenshaw got in touch about turning an L1 Cree into a true pocket rocket suitable for EDC use. He already had a Milky L1 with higher-output drive circuitry so this needed to take things to the next level. The result was the ML1cx2, dubbed 'Legolas,' which brought Creemator-level performance to the L1 platform. Crenshaw posted a great review thread over here to which I added several build photos and a brief writeup... thought folks might want to know about it.
Here are some teaser photos...
Full thread is over here...
Introducing the Milkyspit L1cx2 "Legolas"
Milky strikes again!
Say hello to "Snake Eyes!"
A Project M X542. New generation KL3-BK with 2x Cree XR-E R2 WC emitters in cut-down McR16XR reflectors, mounted on a Tellurium Copper heat sink. Each emitter is seeing an amp. ~542 Lumens.
For the photos, it's riding on a 6Z-BK, with a Z49 tail, but It'll probably live on a 2x18650 tube of some sort.
Another great job, Milky!
One comment on Snake Eyes (which I'm glad you like, Donn) ...the thermal epoxy is actually not so easy to see as Donn's photo makes it appear... one has to look into the head at a fairly extreme sideways angle to see it. Here's a more normal look into the head...
And here's another...
Sorry for the insecurity on my part! Just that I left the copper heatsink unmatted on purpose to achieve a 'skeletal' look... IMHO the copper color offset within the black head itself is nice to look at... and don't want to leave the impression that all one sees is a couple blobs of thermal epoxy, as in truth that's not really the case. I'm probably being oversensitive about the photography, sorry if so.
Sheesh! I didn't even see the epoxy, until you brought it up.
What I did see, however, as I mentioned on the phone, is the quality of the beam. It's absolutely perfect. Whatever it is you do to align the two reflectors/emitters, obviously works. You'd never guess it's more than a single light source.
I've moved it to a Leef 2x18650 tube now, running on 2x A123 cells. Very nice! Any guesstimate on runtime?
What head was this built on Donn/Scott?
Like I said up above, Mate..It's a new generation KL3.
The "New generation KL3-BK" part fooled me!
Just poppin' my head in to say my U2x2 has arrived safe and sound and I've spent a happy week or two alarming the local nightlife. It's beautifully done and even non-flashaholic friends and colleagues are impressed.
Can't understand those for sale threads for this one - it's definitely a keeper.
I'd thought I'd attempt at taking some photo's of my M603 Mother Nature build which I've had for about 6 months now - comes out with me every time I'm on the Ambo and I've had lots of postive comments! It has been an excellent 'light the scene up' light and it's probably soon to be replacement by my next Milky M6 build - a M963 with Seoul U2's!
Anyway, here's my first attempt at photo's on this forum (PM me with any hints!)

What reflectors does that head use?
What a nice lookin light!!
BTW Milky....The "Snake Eyes" looks Really Cool!!

One quick question, What is the current draw from the battery with the Acorn on 1.3A from a RCR123? Estimate of what the LED is actually seeing?
Cryhavok, ideally the current draw would be 1.3A and the LED would see 1.3A... but not all RCR123 can keep up, and not all LEDs are sufficiently low voltage... so in practice, the current draw and output current might typically be in the 1.0A-1.3A ballpark. On a larger rechargeable (less voltage sag) or a pair of primaries the full 1.3A would be more likely. Hope this helps.
Incidentally, the Acorn doesn't have to run at 1.3A... it could also be configured for a max current of 1.0A, 867mA, 650mA, and various other possibilities.
I just got cryhavok's throwy U2by2!
As a soon to be operator are there any info or tips on using this light?
Does anyone else see this on tv and immediately start thinking about Scott's lights, or am I the only one?
Time flies like an arrow, fruit flies like a banana.
My best light has been shipped out to your home Scott.
Keep it safe for me Sir.
Any updates on my two light projects?
Have you tried your P7-direct-drive treatment on a single-cell light?
I have a PentagonLight X1 that would be perfect for the job. I mostly run primaries, so I'm wondering how bright it could be.
Scott would there be room to fit 3 Golden Dragon Plus led's and some type of reflectors into a U2? I was thinking of options to continue your U2 mods since Rebel 100's are not around in quantity and that better color rendering they GDP's are capable of.
I also wanted to know if you think it's the newest P4 with the 2 in the code in the now updated U2, or the older P4. I just wanted an opinion on that last bit, I know you see your share of Surefires!
Hey any chance in that A2 rebel 100 drop-in I have mentioned to you a few times? Not that I can afford it right now.
I do have something I would like to plan and price. I have this 6D mag that I want to rig up for a long running emergency light. I want to keep the output near 100 lumens with a slight warm tint. There are products that come close to what I want but I don't have faith in their small heatsinking in case I have to run the light for hours and hours on end. I am going for efficiency and I know you can easily beat the commercial units in that reguard. Like a super Milky candle! Or do you think I'd be better served with the 22 buck terralux? I'd hate to waste your time.

That said, I'm always up for a challenge... PM or email me if you want to pursue the PentagonLight X1 project, or any other for that matter!
More on the above: offhand I'm thinking the multiple emitter route would do best for overall system efficiency, and I can build better heatsinking into the light this way... plus at that level of efficiency the heat generation will be minimized in the first place. Let me know what you might like to do, I love that sort of project... it's really the same concept as my own #Project-M build methodology.
The A2 hasn't been very high on my priority list... it's not completely forgotten, but isn't getting much active development at present. At the likely expense of the effort, I'm not sure it's all that great a bang for the buck. Still thinking on this one.
On the alternate U2 approach, I have some different ideas on the drawing board. I have looked into the Golden Dragon Plus specs and to be honest, am not all that impressed... for one, they'll be difficult to match with good reflectors... for another, I'm just not seeing the good CRI (color rendering) you cite... from the specs it would appear an ordinary Seoul P4 would render about as well, and a high CRI Seoul P4 would do even better. Am I missing something?
Regarding the new U2A, hard to say which Seoul they're using... my guess is they're buying U1 bins, which are essentially the same as the older U bin... and if they ARE using the older U bin, that would mean the lights are actually using some combination of U1 and U2 parts, with there being no way to tell which you got short of very exact tests in an integrating sphere.
A single level multiple emitter sounds good to me. Especially if I can easily install it and swap mag hosts if needed. Sometimes mags die and I know your part will outlive it.
You are the master, tell me what you think would be best. Going beyond 100 lumens per watt sounds superb. What emitters should we go for? Reflectors, or optics? I have the flood angle covered totally with diffusers and UCL with LDF on it. That said I think some throw would be nice since I can easily flood it out when I need to. Also toughness is way more important than good looks for this one. P4-u2's the most efficent now?

Just curious if you can give me an update on my U2x2. I've been having email issues the past couple weeks, so if you sent me an email and I missed it, I apologize for wasting your time.
