Your gonna love it.
Just wait until dark. And then go play. :bigsmile:
We have two of my nieces, with their families (7 in all) over this week. Should be an interesting Wednesday night :)!!
I was showing mine off all week. My son and daughters friends were amazed. It’s like turning on a streetlight in your backyard. Any light that smokes my TN31’s to me is pretty damn mean. This BTU is mean.
Good idea!,training in preparation for ownership…now that is a sign of commitment

Back again!
Now with XM-L2 and SINKPADS for $15 more!
Awesome,well worth the extra
Is BTU shocker compared, anywhere in this forum, with SP03?
Ordered direct from Ric?
Yes. Same link as in the OP.
You click the selection boxes on the right.
Thanks 
Trust me, the Shocker destroyes the SP03 in every possible aspect.
This was enough clear for me.
Gonna order one.
1B & DRY, right?
That is the brightest possible option available, yes.
Are you saying that the Dry driver is the one to get? I ordered mine without and CW from previous buy. So I got the wrong one??
The other driver has a 3.8A maximum in turbo (with a 3 minute timer before it steps down) and no PWM on any level.
The DRY Driver in turbo is direct drive, meaning if you have decent batteries you can get over 3.8A easy. There is PWM on levels except turbo but it is very high.
Personally I chose the non dry driver since 3000 lumens is plenty for me. Even up to 4.5A the differences are negligible due to 3 emitters being in one host.
That’s cool I was starting to worry that I screwed up. Thanks for explaining it for me.
I should clarify that the differences between 3.8A and 4.5A are negligible due to increased heat decreasing the efficiency of the LEDs.
EDIT: And not to mention you need 4x the lumens to perceive 2x the lumens. A few hundred more lumens aren’t that perceivable (even another thousand isn’t very perceivable, just look at the drop from 3000 to 2000 lumens turbo to high) and just serves to drain the batteries faster.
I believe a DRY DD driver has a point, since sinkpads are being used.
Umm, ok - I've done the XM-L2 U2 SinkPAD mods on both the BTU driver and DRY driver. Who is actually getting 4.5A on a DRY driver? Well, you can't, no way on XM-L2's on copper without doing some other things. You need to copper wire the battery carrier and use unprotected low resistance batteries. The DRY driver is a $5 driver and not worth a dime more than that: cuts out of high in 2 minutes, has poor PWM's in med and low modes. I've seen 4A on a DRY driver running XM-L2 U2's/SinkPAD's with the battery carrier mod'ed. There's the specs and then there's reality....
I'm really interested in seeing what they are doing exactly with these upgrades... Is it worth the $15? Oh sure, most likely. Will you get the improvements I get by custom mod'ing? I'm thinking not, no way, because of the poor high resistance battery carrier, fujik type of epoxy they use, no lapping, thinner wires, same drivers, etc. Actually I'm thinking the SinkPAD's with XML U3's would have been a nice option to offer stock because you could actually maintain the high amps and not have a big output drop over a short time, and still use protected cells.
Notice the posted specs still show the same amps and lumens #'s --- Ok, those lumens (3,500 on high) were never achievable stock, well proven by many. With the AR lens, it went up to 3,000 to 3,100 lumens. Full XM-L2/SinkPAD mod, we are seeing 3,500 - 3,800 lumens, 4,000-4,500+ on a direct drive driver (low resistance cells, advanced carrier mods). I'm guessing with the stock XM-L2 U2/SinkPAD version you will get 3,300-3,500 lumens, maybe. I measure 3.4-3.5A at the switch. If they didn't attempt to make other improvements, the amps will actually go down with XM-L2/SinkPAD's because of the Vf demand, so you don't get the full benefit. Think about it - 3 emitters, 3 cells - ratio is 1:1. so you got the same high Vf issues, and even with A DRY driver, you can't achieve high amps without all the other mods.
It's still a worth while upgrade, just don't expect too much from it. I don't see the getting the typical 20-25% out of it, in fact you may see as low as 10%, or less. With the BTU driver, I have actually seen as low as 10% even with additional mods - seems to vary quite a bit and that's why I'm now doing the Shocker mods with the IOS 3.5A driver.
I’ve never er seen 4.5a out of the dry driver from the Shocker, but I was keeping it high for the sake of argument.
