Probably pretty good :), everything below the BBL & not to warm tint, usually looks the best, like 1A,1D,2A if you like a NW tint that is.
Some like a very warm tint, and then you can start with a much warmer if you like, the warmest i have dedomed was a 3A XP-L and it was pretty descent. But then XP-L’s dedomes nicer than XM-L2’s.
The concept of strengthening bond wires sounded familiar, but I don’t think there have been any tests in BLF. Solder reinforced bond wires? (Dedoming without losing lumens or color temperature)
It is really annoying that Vinz is keeping this a secret from the modding community 
But maybe that kind of attitude is normal at the other forums. Here it sounds very strange when i read about it.
I hope someone more forthcoming work out how to do it, both the stronger bond wire & the dedome without tint shift mod he does.
After blowing 3 XM-L2, I reverted to the XP-L in a TK61 this week. De-domed, the XP-L V5 1A is making 1842 lumens at 637Kcd.
Why mess with the new XM-L2’s when the XP-L will do what you’re wanting?
The 1D’s are U2’s and the 3D’s are T6’s. I have an old cast aluminum Allen dive light that’s waiting on 7 emitters. 
Vinz does not share this secret because he does not only modd lights for the flashlight communities, he also builds small series of (semi) professional lights, on order.
In that respect I can fullly understand that he does not whish to share his expert knowledge in depth with us flashies.
Strengthening bonding wirest and making any dedomed XM L2 shine in CW give him a competitive edge.

Since the leds have no problem being dunked in gasoline for hours at a time , I wonder how they would react to being dunked in a copper sulphate solution plus copper anode , and wired up to electroplate the gold bond wires.Maybe that is Vinz’s method , or something along those lines.
Then he’s going to be pissed when I look hard at my K50vn and eventually figure out if, and how, the bond wires have been strengthened. I think I’ve mentioned it before, but I love a good challenge, if that’s the only way to get high amps through an XM-L2 I’m planning on figuring it out.
He can keep the diamond pixie dust sprinkling. I don’t like cool white beams anyway.
Oh, and lest anyone think I have a problem with Vinz. Nope, I just like learning, and don’t like it when people won’t share. I’d jump all over buying another of his lights if I found the right deal.
2 Different modders Vinh is not Vinz and vice versi! Vinh does a Burn in? Old school technique.
Apparently it’s hard for me to keep them straight.
Originally I was thinking it was Vinh, but assumed I was just wrong with Vinz being thrown around so much. So actually, I was wrong about being wrong.
Also, I’m curious how burn in could improve power handling. Is it not about the power, but something else like improved efficiency?
I believe the XP-L is getting right at 7A, I did initial testing but didn’t test the light once completed and it’s on it’s way to Georgia.
1842 de-domed would be at or over 2000 with the dome on. 
Can we get a close up shot :)
Vinh Nguyen is in Seattle Washington, while Vinz is in Germany.
Vinh is good at pushing things to the max but can’t solder worth a crap and admits it freely.
Vinz is an artist that doesn’t release anything that isn’t perfect. 
(still wanting me some Vinz action) lol
I built up an Eagle Eye X6 host a week or so ago with an XM-L2 U3 1A from Richard that makes 1811 lumens in the X6. I first put a de-domed one in, saw it doing 1600+ with the dome removed and swapped in that emitter’s brother for the higher output.
When I tried XM-L2 U3 1A’s in the TK61 I just did, several fried when pushing 7A. Go figure.
Every time a LED fries, I get a little tear in my eye

Nope. Sorry, but that’s a light I am not going to open up. “My Precious” :bigsmile:

Thanks, I vaguely recall reading something like that now that you mention it. It should stick now.
Here’s a picture of the emitter in the K50vn.
And no, I didn’t open it up, just a picture with my phone through the lens.
Well, I guess your way better then me in taking pictures then……
