Thank you Erik!
Keep in mind if you are going to do a driver swap on these it’s a PIA. A spacer ring needs to be made to get a Nanjg 105 driver to fit. I can post dimensions if any one is interested.
I got mine from easylightbuy. Reflector and optics were free of defects and debris. It had a small knick or two under the anodize on the side, but it was packed really well so I think its a defect from the manufacturer. FWIW this light is cast aluminum, and very soft so it scratches very easy. I dabble into all kinds of gear-centric hobbies (guitars, RC, knives, DIY audio, mountain biking). I have never encountered a metal this soft of any kind. In terms of material hardness its somewhere between brass and solder, much closer to brass though. I have put several dings on mine pack carrying it around. IMHO the manufacturers do little if any QC inspection so its a lotto for sure in that regard.
I wouldn’t hesitate to consider this vendor again… although there are a lot more options to consider now than when I bought mine 3-4 months ago.
Heres mine… FWIW.
Agree, its not the easiest mod to pull off.
My grey one from TMart was in good condition on arrival. Three dings on the edges between the Bezel and Head, almost unnoticeable. Reflector is flawless, clean no scratches or anything else. I swapped out the GITD boot for a light blue one from IOS - goes very nicely with the grey finish.
Kramer, seems like I've read somewhere that the grey annodizing is not nearly as tough as black. Are you saying the finish is weak or the metal itself?
Got mine from Tmart, great condition and fast.
Got mine from DD. For some reason I was not getting anywhere near the current reading that others were getting using 2 different King Kongs, protected and non protected (I modified mine to run two 26650's and changed the driver. Its still a work in progress) and testing with 3 different decent DMM though the driver was the same. Love it. If you want to buy from Tmart I have a 15% discount code left if you want it.
Both I think, but mostly the soft metal.
Looks like Tmart sells TangsFire version and not UltraFire 
DD sells TF version too, for 3 bucks less.
Mines from Tmart and is an UltraFire.
Tmart sells BOTH UltraFire and TangsFire. It seems most of the UltraFire’s sold a while back were gray, as was mine. Now I don’t see gray for either brand.
Apart from lightmalls, is there anyone else who sells the black version?
Tmart. Perfect condition. 4 days. Sturdy white box (not like the flimsy Chinese ones) packed in a puffy envelope with lotsa bubble wrap. No complaints.
Mine is gray/silver. Don’t know about the black.
I'd avoid easylightbuy .. They were quick to take money on lights they never had and couldn't get . Getting money back from them wasn't that hard but a struggle to understand what they had in mind ...They offered numbers of other lights all way overpriced ..For a place that actually looks like they might make a product ....they seemed pretty clueless and didn't know heads from tails ..My guess is I was talking to the wrong end .
Thanks for all of the input.
i was thinking of purchasing a hd 2010 as well. perfect timing on a a new thread.
so i looked at tmart, and they only sell the tangs version. is this just as good as the ultrafire? they have a 3600 lumen with 3xml and the 1200 lumen with one led.
which version is the one that everybody raves about? i think from reading and looking at pictures, the popular one was the 1xml led, but wouldnt the 3600lumen be brighter and better for just a little more money?
The Tangsfire version is a very nice and identical to the HD-2010 but only the single emitter version. The triple emitter Tangsfire is a poor design with horrible thermal properties. Don’t get the triple. There is nothing wrong with the single emitter Tangsfire.
I’ve actually found UF version (TMart) later. So, here you go: gray (brown on pics) and black.
And as I said before, you can buy a black TangsFire for about 30 @DD (with 10% off coupon, of course :bigsmile: )
Sashi, you might order the UF version, but there's a 50/50 chance you'll end up receiving the Tangsfire version.... 
The first one arrived today and had Looks really cool. It’s smaller than I though it’d be, I ordered one from Shenzen and one from…. Dang who else did I buy from, oh yeah Dinodirect
I’ll look at the box when I get up tomorrow as its in my truck. Shenzen cost $40ish with shipping so probably not the most affordable but I wanted to see how much shipping was on a light that size ($17)and now that I think about it. Shenzen must be the one that got here first cause DD usually has some sort of ad with the packaging.
I am not sure why I bought from two different vendors other than to see the quality difference and to find out who was the faster shipper
