I kept kicking the BTU back onto turbo when it started going down. Had to do it multiple times. Was trying to see how hot it got and how well or bad it did when kept on turbo like the the TK75. That’s why I had to take readings about every 30-60 sec. On each light To make sure to keep it on turbo. Check out the video I did on this thread and you can see that it dropped quite a few times.
Thanks alot 
Now one suggestion, i already made a comment on the video, don’t know if you read it, you should put BTU Shocker testing or something like that on it as title, so many users who are interested in BTU can see the test, the video does not show on YT search with that title (numbers) sadly, thanks dude
I will try to do that. Makes sense.
Just got the video titled. Thanks for the suggestion.
Well that was fast, thanks alot
Going Gear is also where I got mine. I picked it up in person and got the 15% off moving sale price. Going Gear is a great place to do business with.
PS. I like their new store. Not so crowded.
Dont blame me just because the stores changes price, tint/bin etc.
I have corrected and fixed many emitters in the past, but I am not not able to update all. Hence the collaboration spreadsheet, where people fix and update things when they see changes or errors.
XM-L2 U2 1A from Lightmalls was added as soon as the spreadsheet got running, 3/3/2013. At that time they were 9,55$, then price went down to 8.90 (updated 1/5/2013) Still described as U2 at that point. . Now they are 8.20, and are not labeled XM-L2 U2 1A anymore. In 1-5 weeks, they could change the info again. Its the way certain stores do things…
KD is the only one who still claims XM-L2 U2 1A out of the stores that got them before/around 3/3/2013. I have shared my thoughts about KD (and other stores like Lightmalls, DX, etc etc) when it comes to emitter claims several times in the past… Latest was a couple of days ago in this post.
Illumination Supply is a great place to get the XM-L2 U2 emitters. I just bought some from them last week and their price is awesome!
So do you think the XM-L2 U2 1A from KD is genuine?
there is a Super BTU out now, is there a super TK75 out also ? how does the new super upgrade cause it to stack up now?
Where is this alleged Super BTU Shocker available? Are you talking about Vinh or RMM’s modded versions?
yea its this one with upgrades,id imagine they could do the same with the other one

Someone could… but that TK75 price tag really limits the clientele. Probably looking at close to $230 if someone were to come along and do it.
I believe VN did a tk75vn, but it’s no where near the Super BTU.
I loose sleep knowing such a light exists and I don’t have it some day someday :bigsmile:
Tom E from this forum is the “official” super shocker builder. There are a few other respected members who have made some too. I’m not sure if Tom E is building them anymore though.
Modded BTU, and modded TK75, both dedomed, driven a lot harder, are actually fairly close. In overall output, the shocker is a bit but only at the the start, and it throws ~400kcd, vs the TK75 at ~300kcd. The TK75 is by far the superior light though... more modes, much better balance, better built quality, and if you add in another battery carrier, to use 8 batteries, lasts forever on one set of batteries. The Shocker is more of a WOW light, than it is practical, but currently it's been surpassed, the modded X60 produces over 7000 lumens, and around 500kcd of throw.
If you want a giant piece of metal built like a tank, and somewhat balanced, the RC40 is a good option. Of all four though, Shocker, RC40, TK75, X60, the TK75 is the mos practical/best light imo.
i have both and without any doubt TK75 xml2 is better flashlight than btu shocker xml
He’s not. 
I asked him to let me know if he builds any more.
RMM mods only now for the SHOCKER? WTS: BTU ShockerVN - The High Lumen Thrower 4500 Lumen (Updated Carrier Post 210)
This light is discontinued forever. Wonder why? :~
Difficult to focus, and not too much of a demand for it, and it's been surpassed.
If you're interested PM me. I used my BTU Shocker VN for maybe 10 minutes in total, it's the same as when I received it sitting in a box. Really should list it one of these days.
I have one posted for sale hwre as well. I love it and would keep it but im narrowing my collectiondown to 5-7 lights so that means roughly 25-30 must go
