Seeing as we may have a HD2010 group buy and seeing as how some members would like to see a breakdown, step by step, on modding one, I will do a series of videos on my approach. How to do a couple of mods to the HD2010 light.
First off is how to tear it down.
Part 2 is the tail cap mod

HD2010 Part 3
Part 4 is here
Here is the final part - Part 5 of 5
I have to change something I said in the final part. The XM-L will give higher amperage, but I am incorrect in sounding like it will give out more lux. The XM-L2 at a lower amp draw will still put out more lux/lumens than the XM-L. Sorry for confusing things.
This XM-L2 ended up drawing only 3.78 amps, compared to the XM-L, that drew 5.05 amps. However, this XM-L2 at 3.75 amps does 40K lux at one meter, where the XM-L does 30K lux at one meter.

Next up is an XM-L2 with a NANJG driver at 5 amps with the Copper Pill.

So, this one also came out 3.75 amps, even though the driver is capable of more, but yet the lux came out 61,500 at 1 meter. I suspect my meter is bad, so I am charging some 18650 Pannys and I will test the meter against the old analog meters, that always read correctly. Digital is just not for me.
I went back and did all the checks again, with fully charged 18650 Panasonics and the amp draws and lux readings were within 5% to 10% of what they were before, so odd as the numbers read, they are as correct as I can get them.
That's all folks...
