Thank you guys for the replies on the MTG2 vs SSR90, I have several mtg2 lights, both domed, and dedomed by Vinh, but haven't ever owned an SST90. Seems like the MTG2 is the clear winner, with both lumens and throw potential if dedomed. (Not to mention the great tint.)
The credit card method, or something similar (maybe thinner) is what I suspect Vinh does, as his dedomes on MTG2 lights have improved drastically from what they were when the MTG2's first came out. First one he did for me was good, but wavy, with the dome obviously cut. The newer lights I got from him, like the mm15, the phosphor is still covered, but the coverage is extremely thin, and incredibly even.
I have received today. I have the same problem
I got mine with mismatched tube too. Nice, but it makes a HD2010 feel like a keychain light. 
A drop of LEDseal will bring back a smooth surface and make any defects/cut lines go away. It's the same stuff as the original dome is made of, just in an aerosol can. Spray a little into a cup, pick some up with the tip of your finger, and dab it onto the LED. It flows out nice and smooth. It starts curing FAST though, you have to be quick. Spraying the LED directly will give a layer much too thick.
Just so you guys understand why I was So Pissed and still am. Here's the reason:
The K5 was the last straw. I told bella that they needed to "check every light" before shipping and look for Defects. Not working, Low output, etc.
What I found out was that they KNEW about the mismatch and they KNEW they had 30 lights that were questionable, but they decided the ship anyhow! Hoping people would be meek enough to just accept what they got. Bella told me this Afterwards when I sent her a long nasty letter.
This is why I did my rant, (even though it was totally inappropriate and mean) and this is why I believe there is no way to continue with these folks, because it goes against what I believe in.
Mine arrived in LA about 5 days ago, but it has just sat there. Going to the Post Office today, to see what the hell. I have had a couple of packages HiJacked in Route. My first Smart TV got hijacked mid-way, in Oregon somewhere. I did get the company to send another. About 4 months ago, they busted a Postal delivery guy in my closest major city with a whole garage full of hijacked packages from High End Computers to Diamond Rings. I hear airport workers regularly rifle through baggage, and the TSA ends up with tons of cash, Rolexes, and fight over the goodies. Sorry OL, you are such a nice Guy, hope you don’t give up on us — Sorry, about Ace/Sup/ giving you the Beam out the Butt.
As part of this group buy (not received it yet), I surely want all goes smooth too. Supbeam/Acebeam making mistake if they think many will accept it as is for mismatch body. Imo, if they fulfill they promise to send replacement, then it is good. In fact still better than many other suppliers, they spend additional shipping fee not just cost of flashlight body. On the other side, those that get wrong body will get spare.
I can’t say for others, but for me, thanks you for arranging this K50 group buy and protecting us.
Agreed O-L
Mine is still in China too or over the Pacific I think. The last track said PVG, which means it made it to the Shanghai International Airport.
*I just got back from a meeting with my local Postmaster, He said:
There had been “some issue” with that particular “group” of packages, but some were being confirmed as delivered in the US, but at the same time, they had no idea where my package was … hmm …

I hear ya and agree with you concerning the deception.
However, if you had these presented to you and us for the amount we paid with the free shipping and knew that there was a color mismatch, we still would have bought them in record time and would feel like we stole them.
It Was and is a Killer Deal regardless of the color issue. I would not say never do business with them again, just warn everyone and be prepared for less than perfect.
When you appeal to a man’s greed, you easily make the sale (Scammer 101)
Everyone who bought those Starry BLF lights a while back put up with a horrible mismatch (more than I can tolerate), but they seem to like the flashlight so they look past the color deal.
Yes, they knew ahead of time, but some examples were way worse than others.
In all honesty, you have to hold the K50 flashlight in the correct light to see the difference, it is not a screaming difference. At least on mine.
The output on the other hand is Screaming:) which is what I need.
I would like to see an earlier batch to see if the control ring is dead nuts to rest of the body as well.
It can get tough when dealing with different materials to get an exact match.
I see brand new automobiles with slight mismatch right off the showroom floor. 2 years later after Mr. Sun blasts it every day for those of us without garages and the subtleties become glaring.
Thanks and no shame on your name OL, you did a fine job putting up with all of us and with the red army.
Later,
Keith
Best not to ever check anything valuable when flying. Especially anything small, electronic, generic, and you can forget about jewelry. Lights stay in carry on... I just take off any assault style bezels.
Good Day Old-Lumens, 
I Very Strongly Agree with your attitude & response to Supbeam/Acebeam’s actions.
Now we will see whether they do as they promised, and Promptly replace the mis-matched faulty flashlights at no cost to us.
Their actions will decide whether I will buy Supbeam/Acebeam products ever again…
…and whether I will recommend them to others…
Thank You Very VERY Much for all You are doing, & have done for us,
Best Regards,
George
