My XML2 BTU 'super' shocker arrived today

This mod was Done courtesy of Tom E. :cowboy_hat_face:

BTU shocker
IOS 3.5amp driver
battery carrier resistance mods
XML2 on sinkpads
UCL

It also came with a free diaper - you will need it when you turn it on high.

Tom measured 3706 lumen @ turn on and 3553 at 30 sec. 179 Kcd throw as well :slight_smile: Thats easily over 4000 lumens at the emitters.

The IOS driver was used because the BTU driver was having issues… only giving 3.15 amps on turbo (should give 3.7-3.8 ) Its a H/M/L with memory driver… which means… NO STEPDOWN.

The output difference is negligible vs the stock btu driver on turbo - Tom measured 3,644 lumen and 181 Kcd on another model with BTU driver.

This thing blows almost every other led light I have ever owned out of the water in terms of sheer output. It beats the blackshadow terminator and thrunite tn30 xml2 by more than 20% in my ceiling bounce tests. Only the heavily modded trj-12 pulling nearly 85 watts on 3 fresh 26650 imrs barely edges brighter, but only for the first 2-4 minutes.

I am very interested to see what Tom can do with the DRY driver since its direct drive… put some sony 30 amp 18650s in there - could we see 6A per led for 5000+ emitter lumens?

I will now say the words we’ve all said - I CANT WAIT FOR DARK!

Congrats on the monster light! Could we get some shots comparing ceiling bounce to your other multi-XM-L lights?

Hi slim - I do not have a number of the lights i referenced to do “side by side” photos or anything but here is some raw data from some of my other posts here and on CPF

care was observed to place the lux meter in the same spot and far enough away not to focus on the hot spot for each test

BTU - 434 lux, to 424 at 30 sec
TN30 XML2 veriosn - 343 lux at 30 sec
Firefoxes FF3 - 550 lux at 30 sec
Trj-12 with KD driver - 491 lux at turn on, 450ish at 30 sec
Trj-12 stock - 288 lux @ 30 sec
Mag458 - 720 lux (dont remember when measurement was taken)
Skyray King NW with UCL - 272 Lux at turn on, 257 lux at 30 sec

Thanks. What a beast.

Contratulations jmpaul320, sounds like a fantastic light.. you can't wait for the dark and I can't wait for the beamshots :D

Looking forward to the beamshots, even though I already have the same thing :wink:

Note - the IOS 3.5A driver is interesting in a Shocker - no stupid 3 or 2 minute kick down! I got another on order I'm planning to use on a MT-G2 build.

now that sounds interesting….
is that for you, or for another member?

Post the beamshots when you have them, please.

I’m interested how far the BTU outshines the Terminator.

Brother I own both the Terminator & a hot Rod BTU. I like both of them. But the Terminator can’t even come close to the BTU’s distance. The Terminator is a 300 meter light, whereas the BTU is a 600+ meter light.

the only reason i sold my terminator was because of the pwm on low - it was way too low of a frequency and was a disappointment to me, other than that great light!

at least this explains what those mysterious lights high in the sky over LI Sound were last niight - just another BLF member w a monster build BTU…gotta get one!

and to think i almost went 1 month without getting a new light!!!

Contratulations jmpaul320.

Oh! :open_mouth:

So the BTU will leave my brightest lights - the Terminator & the X-100 - far behind. :frowning:

Thanx for the tip Dale. I’ll be setting my sights on the BTU then instead of the Convoy L2. :slight_smile:

Don’t feel bad Nightbird95. The TK75 is my favorite light and is one of the few stock LED lights that could give the BTU a run but straight out of the box the BTU is slightly brighter (with the A/R lens ) and out throws it by about 100 meters. Modded I am pretty confident that it will even trump the RC40. I had to buy me a shocker too.

jmpaul320,

You know how much I value your opinion and how I know from doing business with you that you tell it like it is. I repsect that in anyone who can do that. And really it’s the way it should be. But your posting this upgrade here has got me very much interested in having my BTU upgraded as well. But I will wait to see how I like mine as is. But thanks for bringing this to my attention brother.

Brad

For me, for a change! Didn't even order the host yet, but will this weekend - gonna use the T10B from IOS. Should be a blazin, long pocket torch.

Brad, I know that question wasn’t meant for me, but just curious why you would hesitate on getting a BTU modded. For money reasons or for the hassle I can understand. But it sounds like your concerned with resale value.
This is the way I see it -
My stock BTU - 2880 lumens and 125K in throw. That was before they had the AR lens. Great numbers yes. It did loose lumens pretty good though, with about 10-15% loss (keeping it on turbo) in 20 min run time.
My modded BTU - 3670 lumens and 181K with XM-L2’s on copper and UCL lens. Both tests with Keeppower 3400mah protected cells. And now the power stays VERY well. Haven’t done a long term test again, but it actually gains power for a good minute or so.
AND keep in mind this light was built by one of the best modders on our forum - Tom E. He goes through the trouble to polish heatsinks with 2500 grit paper and other minor things like that. He does this to make excellent heat transfer and peak performance.
So how could a light that performs roughly 25% better than stock and has MUCH better heatsinking and power holding ability be less value than a bone stock light?
I’m sure as I type this, Tom E could easily start selling his quality modded BTU’s for $150 at the same time Ric is selling his stock ones for $99. Ric would sell more I’m sure since $150 is more than many are wiling to pay for any light, but I would be willing to bet Tom would have more light orders than he could handle.
Not knocking the stock BTU - I’ve always been a big fan of them. Bone stock they were the best throwing and high power light on the market. The TK75 was its only competition. Now the much more expensive RC40 has passed the stock BTU on power, not throw though it appears. But modded they are more powerful and now have quality to match some of the best lights out now. And it matches or beats the top dog RC40 in power and KILLS it in throw.
It’s a win win in my eyes. You might be totally happy with your stock BTU - many are. But if you want more, don’t hesitate to get it modded. You won’t regret it.
Hope you don’t mind me butting in with your questions for jmpaul.

Yeah the BTU is definitely my next target. Thanx manxbuggy1! :slight_smile:

I forgot that I’ve seen beam shots of both the Terminator and the BTU already together with other very bright lights. That was rdrfronty’s post on your trip to Big Bend. The BTU indeed leaves the Terminator behind. :wink:
