BTU Shocker Mod - XM-L2 U2's/SinkPAD's

Anyone else do a tailcap reading across the switch?

I'm curious what others are seeing measuring amps this way, if you get in the neighborhood of 3.85A or not. I think one of the reviewers noted 3.6A on turbo.

I’m not sure if these springs would fit or not but I have used the ’’A” ones and they are very stiff. On a 5 amp driver it makes no difference to the current if the battery is resting on it or being pushed hard with the spring on the driver and tailcap measurements being taken.

Yes - I used these on one Shocker - makes a very tight fit for KP 3400's. 5 amp driver? Stock Shocker driver is supposedly 3.8A and the DRY driver is direct drive, so it's higher based on lumens/throw I got but didn't do a tailcap reading...

Ok guys you made me confused, so please help with few questions!

1. Doesent all BT shocker already come with U2 lens as stated on CNQG site?

2. Doesent all BTU Shocker already come with better lens as of lately then the old revisions? what lens are you guys using to mod?

3. What driver should i pick during my order, DRY vs BTU what are the pros and cons, does it really worth it to go for DRY?

4. I got some high end thermal paste, Artic Cooling MX-4, it beats Artic Silver for whole 2c, should i use this, instead of the stock - to mod the cooling, is it easy to replace the paste?

Thanks guys!

1 - XML U2, not XM-L2 U2 -- new generation of CREE emitter

2 - they always said AR lens but it wasn't an AR -- now it actually is what they say it is

3 - DRY has poor/low PWM's and cuts out of turbo after 2 mins, while the BTU driver has no PWM's (I think?), 3 mins cutoff from turbo. I believe the BTU will keep output more consistently as the battery drains as well

4 - Well, depends on your definition of easy, and if that's the only mod you do, probably not worth it -- much better to get those LED's on copper stars, SinkPAD or Noctigon

Thanks dude, can you provide me links where can i get the Leds (reliable site/seller i guess) as well as those Sinkpads? sorry i’m not moder my friend is, so this is all totally new to me, keep that in mind :slight_smile:

So what i need is,

Leds, and sinkpads only to make this light noticeably better, also replace the wires in the flashlight with ticker ones? thanks!

best source for LED's for this mod: https://illuminationsupply.com/cree-leds-c-52_36/cree-xml2-bare-u2-1c-tint-6500k-p-279.html

Cheapest copper boards and best price: http://intl-outdoor.com/noctigon-xm20-copper-mcpcb-2pcs-p-713.html, or get 20mm SinkPAD's from VestureofBlood (BLF'er).

I use 20 gauge silicone, gotten off of eBay, but it's pricey - can't find a better/cheaper source though. You get like 30" of red, 30" of black for like $10 with shipping - way too much...

Thanks alot, are the LEDS cw? sorry im new to this stuff as i said, thanks one more time :slight_smile:

Tom do you offer your modding services on the BTU?

Well, I have done a few for fellow BLF'ers, but really need a break - been buried in mod'ing every evening and all weekend, still need to work, and got other things going on, so afraid I need to turn new mod'ing work down for now. There's always the risk luming over my head and I've had some close calls recently, and diffculty keeping track of all on-going communication -- just a lot of time & effort, and it's been getting crazier and crazier...

hey completely understandable - just figured i’d ask

good luck with everything!

thats what happens when you do good work lol

Thanks!! I got a pile of my own stuff-to-be-mod'ed as well, need to catch up, a little anyway...

Is it advisable to dedome the emitters of the BTU Shocker? Has anyone tried it already?

vinz did a mod on the shocker with dedomed xml2s… it was around 380-400kcd i believe… it required shims and focal point adjustment to get the emitters to focus correctly

I have not seen it done yet.
The reflector design does not allow deep focus adjustments that are usually needed for dedomed emitters. The wires will probably short out on the reflector. With some serious reflector mods, you might get this to work.
Edit: OK, I stand corrected :smiley:

Now the BTU shocker can come stock with XML2, just when I bought one and being told by Ric it will not be available for a long time…
I hope I can replace the LEDs easily.

Thanx jmpaul320. I guess I’ll stay away from dedoming the Shocker - for now. :slight_smile:

I have the original BTU (dry/cool white) but also have another on build order from one of the wonderful people if this forum. I think down the road I will mod my original BTU but I really need to learn a lot more on some cheaper torches first before attempting a mod on a pricey one, just to be safe. :stuck_out_tongue: Its nice to see the option for XML2’s, although Ric doesn’t list outputs for these models. I would also be interested in knowing what sort of mounting they are using (sinkpads/copper star/alum star etc).

I have been trying to figure out how to make Rics volume price points work…BLF group buy instead???

Buy 5 @ $95 each.

Buy 10 @ $85 each.

I am all over the qty 5 price to one BLF member but by the time you reship USPS or UPS, you’ve probably blown through $20.

Maybe Tom E would change his mind, do the emitter, driver, sinkpad etc mods and do an I-95 run one day…great time to leave L.I. and see the rest of the Sound area.

Can’t wait to see what the feedback is on the new XML2 option is…
