Awesome effort from all involved it seems. Thanks OL for making it happen.
Now for a driver, whatever that is, and some other bits probably.
My Grey SKU 88007127 Pill is 30.88mm . The Copper Pill should fit.
Your pills not fitting would be a deal breaker for me, unless we could get a press fit copper slug. But I think it’s a moot point as neither of the lights being sent to OL is grey. I’m still in either color.
Hmm when did you order it?
Copper pill:
Two year old HD2010 pill that I based off the copper pill from:
Grey HD2010 SKU 88007127 2 months old:
Those images are horrible! Must be using a Nikon! 
LOL!
I CK My TMART Acc . Ordered 10-31-2013 . Shipped ?
Watch out, a Canon fanboy! 
I ordered mine at 11/29/2013, probably from a different batch.
Not sure what they’re sending out these days…
Thanks for putting this together. I have two already, but would probably be in. 
Yes it is a Lottery . Also the lights OL tests may not be the same as what is shipped for the GB .
Very true, but I will endeavor to control that if at all possible.
Good luck on that. Your best magic wand will have to have the dust cleaned of it I say in jest.
This is my official entry for winning one of the three lights being sent out. Thanks.
OL Thanks for the GB + Good Luck. The problem is Tmart may not have 100% Control over Build Quality + Performance, or will they be CK + Testing every Light?
I have the gray SKU: 88007127 on 12/21/13 from the US warehouse and it’s the larger pill.
The threads looked the same to me, what do you think??
The thread pitch? Yeah I think they’re very similar.
Are these a standard Metric size?
I looked at charts and it did not make sense to me.
No. Manufacturers make there own size threads up for I assume to match whatever material they have.
I am in for one. Thank you.
Well, samples are definitely on the way, but it will be the "normal" shipping, so this will all come to a halt for a couple weeks or more, till they come in. At least I can compare build quality and do measurements. It's a base to start with and if all the lights can come from one run, then they should be a little more consistent.
They may be 0.9mm but I couldn’t get a precise measurement.
If there’s enough interest, a second HD2010 copper pill run may be viable. Thanks OL for your efforts.
I think this is by far the best way of figuring out which light will be the best to buy.
Other than taking a little time all questions will be answered once they arrive.
Thanks for all you time and effort in trying to make this Group Buy work.
