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!
Do we need to do special adjustments on focusing the dedomed emitters? Or setting the emitters it its original set-up would do just fine?
I'm no expert at focusing, but it looked pretty good to me as is, with the stock plastic alignment pieces - beam pattern has the usual clover effect on the outer edges of the spill and center beam, but I see the same thing stock. I heard they needed focus adjustments but I don't see the need - no dark spots, throw and output seem appropriate, etc.
I'm thinking yes, perhaps... I assume you mean measuring distance, and 8-15 meters would probably be better. It's scary - also the #'s would be better with Samsung 20R's - maybe test this evening...
Bow-down to the BTU Master!
Holy crap
Oh! That’s what I needed to hear! 
I’m dedoming the XM-L2 T6 1Bs of my BTU tonight! J)
Thanx so much TomE! :bigsmile:
Now grasshopper, it's all in the amps. Pump enough amps into these XM-L2's and good things happen, well things will get heated up for sure... 
Good thing about the Shocker is the 20mm copper stars are spread out nicely on that huge pill surface, and you got a lot of aluminum mass around, though I would like to see the pill top thicker. I think the pill top of the XinTD X3 is actually thicker.
By the way TomE, which resistor in the BTU driver did you put a jumper wire on? Is it the sens resistor which connects to the negative lead wire?
Not the BTU driver - never got the resistor mod working on that driver, gave up - PilotPtk posted it, but I couldn't reproduce his result. I'm using the IOS driver, this one: http://intl-outdoor.com/xml-multicell-circuit-board-45a-ouput-55126v-p-543.html, but the versions I have are 3.5A - Hank updated these to 4.5A by resistor mods. You can clearly identify the current limiting resistors because they are 2 joined next to each other, maybe even stacked. The 5A LCK-LED driver is identical, though I didn't try one on a Shocker yet.
I’ll stick to the stock BTU driver then. The 3 XM-L2 T6 1Bs are now soaking in gasoline. I can’t wait to see the resulting lux readings.
Thanx again TomE! 
Those are some insane numbers, competitive to 60-85w HID in both lumen and throw. Who still want a HID NOW?
I did not fond the larger form factor of shocker. But I should think about it again……
Just finished modding my BTU Shocker! :bigsmile:
I dedomed its three XM-L2 T6 1Bs then re-installed it back to the shocker. I replaced its AWG 22 silicon wires with a new set of the same wires because the silicon protection of the lead wires also dissolved in gasoline. :~
I used the same stock BTU Shocker driver which gives a tail cap reading of 3.35 Amps at 12.04 volts. I then turned the flashlight on and TomE was right - the same flowery spill with a little tighter hot spot. The only difference is that the beam is already neutral white and 3 dark spots are still eminent in the hotspot at 2 meters. Lux readings at 3 meters might not give good results. :~
I took the lux reading at 6 meters and the result was 5341 lux which is equal to 192 KCD at 1 meter, a 44% increase over the 133 KCD stock readings.
My Shocker now beats my modified T-08 in throw and I’m loving this light even more. Thank you very much for the tips TomE! 
Hhmm, 3 dark spots at 2 meters. Hhmm. Didn't notice that - I'll re-check this evening. Tailcap amps remained the same? I'm thinking you should have gotten double the kcd, or close to double, because I'm thinking that's what I'm seeing, but my amps are way higher, and using U2's.
Its not that dark, just not as bright as the edges. Its more like 3 doughnuts that did not converge fully yet.
I did not get the tail cap readings again because I did not do anything to the BTU driver. I just assumed that its the same 3.35 Amps like when the LEDs were not yet dedomed. :~
Or am I missing something? Does dedoming the LEDs change the tail cap current? :~
Tom actually you have one more thing that can experiment with the BTU Shocker…
Triple XP-G2 de-domed, driven at 4.5A.
With the trade-off of lumens, not sure if we can see over 600kcd from there.
now we gotta add this to the mix in the throw competition against vinh’s tn31 and k40’s!
…i do have a vinh k40 and tom shocker ordered though…hehe
