I actually published this in an unrelated review, but thought I should add it here. Outdoor beamshot of HD2010, 30 ft to the small tree in the foreground and 60 ft to the large tree behind it:
I have probably 20 EAST-92 drivers (the stock HD2010 driver)if anyone needs one for cheap send me a PM.
You have better luck than me.
Ordered these from eBay. After 3 pcs I gave up. They could not fill the batt more than to 3,95V or so.
Before, I had one or two GOOD ones.
Once ordered a EU-plugin version and discovered that it was completely useless because of wrong lenght in the plug = cannot connect to wall socket…
I paid a little more money and got mine from Manafont I haven’t got a bad one from them yet
This is probably the case.
I had the same experience as CheapThrills regarding this charger (got it cheap of ebay).
I got it to charge my 10440’s that i was destroying with the 500+ mA chargers.
Although this is probably to high current as well.(320mA)
Only charges Li-ions up to 4v or so.
Is this light available anywhere in NW?
I just bought one
satisfied
Just got mine 
looks awesome short test with a 18650 working fine.
Tmart’s packaging was less than desirable very similar too SashiX.
Test driver at full battery 4,16v have 2,75a. How much lumen ?
Sorry, My English so bad. I am from Vietnam.
Well, according to the chart by Match found here, you're around 850. You probably have to figure some loss for out-the-front lumens (20%?). Someone else would have to chime in on that.

Oh, thank you Garry. Thought is 1300 lumen. But in fact is 850lm.
I also feel satisfied because the beam convergence. Distance of 200 meters I can be clearly seen.
The "1300 Lumens" (and similar bogus unrealistic lumen ratings) are what we call "Chinese Lumens". They are just lies for marketing purposes. You can review real world tests (along with Cree data sheets) to see the "true" outputs of various LED's. Realistically the XM-L T6 bin tops out around 850 lumens though. You'll catch on to their game as learn more.

*Yes, I think so. Is there a way to make it brighter ?
I’m a new member , not very familiar. *
Yes, running the light with a 26650 is necessary for highest output! Go with an INR King Kong!
The problem with resistance mods in this light is that you may burn out the LED due to the driver being direct drive. Also, if you haven't gleaned this from the HD2010 threads yet, be careful of the reflector shorting across the LED's connection wires. You'll probably want to add some sort of insulator between them. (My HD2010's LED is apparently burned out and I can only imagine it's from shorting these leads by the reflector.)
-Garry
Oh, I think so. I am using cell 18650 of Sanyo 2600mA. Maybe not strong enough.
Tried to Panasonic 18650 - 3100mA, but not other…
I will be looking to buy, ( not sell in VietNam ) and try again…
tomorrow, I will replace wire…
Thank to all, you really enthusiastic…
Awesome review mate. Is this light current regulated on high at least?
edit: its direct driven 
FYI - a lot of people are having E1320 mod the HD2010 pill with a Nangj current regulated driver (extra AMC chips for about 3.5A total output). This is my plan too.
-Garry
I also switched the emitter on mine to an LCK-LED U2 as well as the driver change. It appears to pick up a little more on top of the driver increase.
LL5GHUFU coupon is dead.
Is there any other?
