The HD 2010 results are kinda blowing me away, but think I nailed it with tight-fitting a trimmed 20mm star in there, and sanding star and top of pill surfaces all the way to 2500 grit. The HD2010 pill is far from stock, lots of copper added inside, plus a small brass pill, but I didn't touch the pill from the pre-mod. Maybe the SinkPAD though gets some real advantage from this. Oh, also got a UCL/p lens in there, also pre-mod.
Oh, also, I left the SinkPAD indent on the bottom as-is, and used Arctic MX-2 grease rather than epoxy I had before. Filled the indent with grease though.
Having seen the impact that lapping can have on CPU cooling the results with the 2010 seem to show what can be achieved with elbow grease. I can see now why people were getting excited about these.
It’s not. The XM-L2 U2 is 387 lumens brighter than the XM-L U3. Sure makes my stock HD 2010 look sick. Lol. It ended up 770 lumens otf after 30 seconds and throws about 53k
I’m assuming those are tail current measurements, not current at the emitter, so assuming the measurements are accurate - driver efficiency, and the acceptable deviation of emitter performance (7% range for each bin?)
flashlightlens.com - it's a little big, think it's thicker. You got usually 1mm to play with in width. Pretty sure I can't fully screw down the bezel as far as it used to, but its over the o-ring.
