No pics of the mods with the stars mounted?
I’m interested in the easiest way to lap the bottom of the sinkpad stars and the heatsink surfaces?
ohaya, I meant the driver is now a glorified piece of wire. 
I think I reversed the polarity on it and that caused it to release some magic smoke. I still have it intact in a bin of replaced drivers, but there’s no physical sign of damage that I can see.
simplec6, the easiest way to lap a star is to use gradually finer grits of sandpaper on a flat surface. For each cycle, sand the bottom of the star until it has a uniform finish. Then repeat with the next finer paper. I finish off with a mirror-like finish at 2000 grit. Others continue to 2500 grit.
Based on this result, I think 2000 grit is acceptable.
relic,
Looking at your “mirror finish”, I’m starting to realize that I don’t have enough patience for this hobby :(!
Neither do I
In reality, you don’t have to go that quite that far. I just figured I might as well since I was a few hours in already, what’s another 20 minutes 
I’m sitting here at work, waiting very impatiently to get home and play with this Shocker Tom E modded for me. I have a sucky point and shoot camera, but I might try to figure out how to take some comparison shots with my other throwers (TN31, TK70, Flexcandles Asgard). Unfortunately, I do not have a lux meter, so I can’t do any lux testing either 
I will, however, be happy to test the current at the switch with some different batteries. I have the Samsung INR18650-20R batteries which have a rated max discharge of 22 amps. I also have some NCR18650PD’s on the way, but they probably won’t be here for a week or two. I will try and post as much info as I can.
A big thanks to Tom E for modding this light for me! I absolutely cannot wait to get home and play with this thing.
A tip from the CPU heatsink lapping savants: Go to a local glass shop and ask if you can have a piece of thick (5/8” to 1”) scrap glass. It is the flattest, hardest, least flexible surface you will find and is about as good as it gets for making sure your lapping is completely uniform and flat. If you want a mirror finish after using sandpaper, you can polish it with some 3M rubbing compound.
Very nice finish, but just solder the MCPCB to that big board, thermal pastes or glues are not going to match solder conductivity of around 60W/m.K
hey orairwolf, i had a tk70 , and it was a beast. can you give me some comparision notes to your tk70 vs your modded shocker.
There’s no way I’d ever be precise enough to get three emitters perfectly aligned in the reflector holes while soldering them down. I’m sure it can be done, just not by me.
Updated the OP with info on latest de-domed Shocker...
That is some sick numbers! :love:
5.7A: 4,100 lumens at 30 secs, 467 kcd
HOLY MOTHER.
Awesome job Tom!
As usual, I just have to ask, for how long time do you see 5A+ 4,5A+ and 4A+ with those batteries?
They are not exactly high capacity..
Updated OP with maybe some info that might answer this - bottom line is not very long... 
. You don't want to go out for a stroll with this thing on high. Of course your arm would tire, you'd drop the head down, then go blind from the reflected light off the ground... Or, you would get that warm, cozy feeling working it's way up your fingers, and figure you'd better drop it to medium or low, rather than just dropping it before that funny smell you are noticing... burning skin... Medium mode though is 2,000 lumens - gotta love this thing!
Thanks, If I should ever do something similar, then I would probably just stick to some 2900mAh PD cells.. And some emitter mixing..
Agree - Pana PD's are a nice compromise, but even on KP 3400's, it's an incredibly powerful light that would get at least some runtime. We kind of reached the limits on this form factor of 3 LED's, 3 18650 cells. This just kind of proves what's possible, not necessarily practical.
Tom,
I think you have taken the BTU Shocker to its highest level.
Well said, I think you hit the nail on the head there. When that is said, who would not like to own one and see what is possible?
Tom E, will the throw number increases with longer distance?
that’s boss! i knew you had something up your sleeve tom! looks like you perfected the shocker.
now im glad that my shocker was on your queue and not one of your earlier shockers. but your earlier shockers were no slouch either, its just that put polishing touches to the already madness.
way to go bruh!
