Foy has the light output sag listed in his first post with the stock pill, led and driver.
Thanks!
Too bad I have no Lux meter…
Initial sag seems to be pretty high compared to what it sags later on.
Anyway, here is the pic:
Always a bit iffy to solder places with good heatsinking but this was easier.
There is plenty if extra in the Drivers cables, so I took LED aside, soldered cables first and made Thermal pasting (GC Extreme) & contact afterwards! 
Hi there! I received my hd2010 today from tmart. Package was slighly damaged and lamp had scratches but that didn’t bother me after three week waiting. I installed 26650 battery and wtf?? The threads of tail cap were really tight but installed tail anyway. Now I can’t get the tail cap off… Other thing is that only high and strobo modes are working. So now I must contact tmart and propably send the light back and wait another 3 weeks or what is their way of handling issues like this?
edit: first time I inserted battery the threads were tight, then tried 18650 battery and all modes were working, after that the jam happened when I put the 26650 battery back. Now the battery is stuck also in the lamp… I wonder do I have to broke the lamp to get my battery off or do I have to send the whole package to tmart…
the same thing happened to me just the other day. i thought i was screwed too. i was able to get it loose though by spraying wd 40. see if that works for you…
You can remove / unscrew the head from the battery tube and get the battery out.
Yeah!! Why didn’t that came in to my mind. Thanks!
Have a nice time here, kottero!
Let me guess: XM-L U3 from LED-Tech?
My HD201 from Tmart sequence goes like this: Press fully to turn ON, always starts on High, half press to cycle through, Med - Low - Strobe - SOS. With flashlight turned ON, half press for at least 3 seconds on ANY mode and it will return back to high.
My modded HD2010 has now 120000 Lux 8)
…dedomed.
With: XM-L U2, 7135driver=3,7A, UCLp
before dedome it was 57000 Lux.
where did u get the ucl from?
I buy a little bit bigger one from flashlightlens ( UCL*p* ) and use a rasp. 
Andi, what method did you use to dedome it? I dedomed my ZY-T13 using the “run it till hot and peel off the dome with your fingernail” technique but the lux didn’t change. I still only get 39k out of it. Horrible!!
I use a razor blade and cut in the dome a little bit on the opposite side of the bonding wires. Then use tweezer, hold star and press the dome directly on a cookplate(full power) for 25sec.
Then lift the dome with fingernail at the cut.
Most time it works perfectly.
When you say a “cookplate” are you talking about the stove top? As in red hot glowing element?
translator say….yes, i have a ceramic/glass stove(hob). 0:)
I have an extra xm-l u2 on star and an HD2010 and a ceramic top stove….
Any guesses what I’m trying tonight?
Iv got a U2 led & a 4amp (intl outdoor) driver firstly will the 4a be overdriven with the U2 & secondly what’s the easiest way to sandwich the smaller driver in? This will be my first proper Mod iv only just replaced my small sun C10 driver to a 105c successfully yesterday has some good THROW now! Cheers in advance for any help!
Do you have a link for the driver to get an idea of the size?
Think it’s this one http://www.intl-outdoor.com/4a-3mode-2745v-circuit-board-p-546.html will that work?
