UPDATE 10-05-2016
FOR THOSE THAT HAVEN’T MADE AN INSULATING WASHER FOR THE BOTTOM BRASS PILL IN ORDER TO AVOID SHORT CIRCUIT WITH LARGE POSITIVE CONTACT BATTERIES: PLEASE CONTACT BANGGOOD WITH PM, THEY WILL SEND YOU AN INSULATING DISK.
UPDATE 09-05-2016
Consolidating a few of the various fix posts so people don’t have to trudge back ~15 pages.
UPDATE 01-05-2016
1) From when i received the sample i never had a shortcircuit or malfunction, it is obvious that i would have say. I tested KeePPower 26650 5200 protected, LG HE2, Panasonic PF.
The problem as i read in the previous posts is the difference in the diameter of the positive pole: Efest have a wider + pole than KeePPower. So only with some battery the positive contact touch the brass pill creating a shortcircuit. Neal has find a solution with adopting a plastic washer on the pill. This will be included in the next batch.
I will remember that i have NEVER requested a 17 mm driver but a 22 one because of the dimension of the JAX Z1 pill in fact if this had been respected this problem never happen.
2) Some members report a possible short on the anodized cover with cables soldered on MCPCB. The anodized aluminum don’t conducts electricity (thanks to anodized threads a 1/4 turn on most flashlights permits lock out). The only reason why this cover can cause short is some sort of damage on anodization in some lights. I will ask Neal to make some type of insulation on next batch.
Members that had short circuit with melted springs or a light that doesn’t work please send me a PM i will try to find a solution.
Some specs not respected in production.
-In the OP of this thread i declare the use of 20 AWG cables. Now i see 24 on production one. I don’t understand why change a spec commonly agreed with manufacturer.
UPDATE 20-04-2016
I counted the COMETAs that need to be transfer to EU Warehouse: they are about 400 from CPFi and BLF.
As stated above the stock will be available in the EU warehouse in 10 days: once there Neal will send the new coupon.
Also 100 Keeppower 5200 mAh IMR will be transferred jointly.
UPDATE 06-04-2016
The COMETA will be ready before 15th April. 
Final Sample
For teardown see post #583
UPDATE 6-03-2016
I am glad to announce that the COMETA will have the same driver as the BLF X6v2 and the BISTRO UI designed by ToyKeeper!!

List of the personalizations, technical and aesthetic:
LED
XP-L HIGH INTENSITY CW and NW available
Available 1A CW and 3B NW bin tint (possibility to have a BIN with lower color temperature)
MCPCB
MCPCB in copper Noctigon XP20 with Direct Thermal Path.
Thermoconductive paste
Application of a layer of a quality termoconductive paste between pill and the MCPCB.
Cables
Certified cables connect drvier to the MCPCB
Given the high current, 20 AWG cable were chosed.
Driver
Driver 22mm FET + 7135.
Springs
2 gold plated springs: one long and flexible (to adapt different to cells with different lenght), one thick and strong (to ensure optimal current flow).
This solution was used in the manker T01 and looks like it is capable to perform as well as a “sping bypass”
Our sample should be here next week 
. Estimated cost will be $45. The goal is to reach 500 units combined.
