Review: BTU Shocker (3 x XM-L T6 NW | 3 x 18650)

DENGOH: Since we are comparing TK75 and BTU, why TK75 can have same output in Turbo for 20 minutes even it is lighter than BTU? The weight sure help BTU, but I am saying it is not performing as good as TK75 that is lighter.

DENGOH: You can stand up, hold BTU in your hand, try switch it on with one hand. Then you see why I say it is lousy tail clicky. It is such a heavy light, it should be side clicky.

DENGOH: I myself find the battery carrier to be very ugly so springs protruding out. You can compare it side by side with TK75 battery carrier picture. I don’t know what happen to those after sale services. It is good Ric is filling up the gap where BTU is stated to have AR lens.

DENGOH: rdr already confirm TK75 has slight higher output than BTU after 10s, or I should say they are equal in output. But BTU does it with very high driving current though some claim it will not harm LED, but it is out of CREE recommendation. The point is BTU has to go beyond manufacturer limitation to be equal with TK75. TK75 is not driven as hard as BTU even though rdr assume it is because someone already measure TK75 using power supply.

DENGOH: I agree with you not much difference. The point is since the whole thing is about boasting BTU Turbo performance, so I point out BTU weakness that it can only do it for 3 minutes. RDR claim no problem to use BTU in Turbo mode as long as he likes, but he doesn’t try it. I asked rdr before to switch BTU on for 10 or 20 minutes, always put it back to Turbo mode when it step down, and record the output with light meter. Seriously, I think we should think about why BTU limit it to 3 minutes in first place.

DENGOH: I dislike bad quality product that charge for premium price. If BTU is selling at $100 now, I am okay with it. But it looks like it is not as it involve SRK in the purchase. When I see people boasting about their product, I can’t help to voice out. I don’t openly bashing BTU everywhere, it is only after someone boasting BTU and I will voice out there are better choice.

Sorry to others who like attacking, attacking statements are ignored by me. I don’t study psychology but I am not easily provoked.

See my reply to Slewflash. I don’t think I am biassed though. If BTU is selling at $100 in current package, and I am still bashing it, then I am biased.
Remember it was aiming $180 and use $150 to lure everyone to buy in current package. Now Ric is filling up at least one gap, that is AR lens, I look forward to see how the lens look like.

Yes, in my review I also questioned the choice of using a tailcap switch.
At the time of announcing it was one of THE best lights out for the price (TK70 head with 18650s? Ingenious). I agree that the TK75 may look better but they’re for different purposes. Neither is better than the other.
If someone wants throw and high output why would you recommend a TK75 when the Shocker is clearly the better choice? But of course if you want more flood and high output you can just get a TK75, or if you want even more flood then a TN30.

Technically the BTU Shocker is still $150; you get a $50 coupon to buy more items from Fancyflashlights. It has nothing to do with the SRK (unless you want to use the coupon to buy one).

Since their output is about same, TK75 flood better, BTU throw better, might not noticeable to human eye, then I think from usability or quality point of view, TK75 is the better choice.
1.Longer runtime
2.Lighter
3.2 years warranty
4.Better UI
5.IPX8
6.AR Lens
7.Shiny Reflector
8.20 Minutes Turbo

DENGOH: It is not $100 like you say.

IS the ar lens available for the btu ? I hope Ric sends me one after i told him im a fasttech customer now

Ric should make available for the BTU ...AR lens , diffrent reflector designs ( for flood or throw), diffrent digital drivers if choice !!!!,the driver holder ring,the leds can be purchased as newer and more powefull once get available, battery carrier is already available and an upgrade would be nice , and this light would be the mother of all hosts for modding and upgrading since heat decipation is a non issue with its thick body ! itl stay with the pack for many years to come. This is a flashaholics light after all so needs lots if optional parts and accesories available .selling parts and accesories for the btu will get him more cash then selling the light itself :) I know i would buy a "flooder " reflector design.

Hey DENGOH, the TK75 throws like a little girl compared to the BTU. The BTU is the undisputed throw king of multi-emitter lights. That’s why people buy it, duh. I don’t know what your fascination is with the TK75 having magic xmls that produce more light with lower current.

can anyone with a lux meter ,take readings with lens On and then take reading with the lens off and tell us the diffrence.

I want 3 de-domed xp-g2 in mine.

tecmo is krazeeeeeeeeeeeee

That is completely not true. TK75 is one of the best thrower and flooder in one light. BTU is just copycat of TK75 brother with no new innovation in it. Glad you love your BTU though. No, people are not buying it unless get trapped by all these boasting.

Aha! There’s the issue! The 75 was bought with the expectation it would steam roll the BTU. When it didnt. A case of EBHS ( EXTREME BUTT HURT SYNDROME) developed. Then the evil RDR came in with actual fact ( which were as welcome as a transvestite prostitute in the vatican.) Thus compounding the EBHS… & here we are… LOL

Nope, sorry. BTU throws the best and is just as bright. I feel sorry for people who listen to you and buy an inferior light for more money!

The TK75 is a great thrower and flooder but Dengoh the BTU outthrows it by a 100 yards. This is not just speculation. This is what me and my brother observed in multiple tests with a light meter at multiple distances. Period. As much as I love my TK75 I can not and will not say it is a better light because it is not. In my opinion the BTU isnt better either over all. I promise if you get either one in cool white you will be impressed with your light. This is just a matter of personal preference. As for the R&D in the Fenix making it better, that also is not true. Fenix was once a new comer in this industry also and look what it has become. BTU has a very strong start with the quality of the shocker and I can see them going places. Sorry just my $.02.

First of all, I think the BTU and TK75 are both good lights, but after looking at the beamshots here - I have to say the TK75 and BTU are pretty close at 300 meters - the zoomed in shots look very close.

The zoomed in shots are definately dark. I am going to work on my settings a bit this weekend and see if I can fix this problem. The lights are equally impressive with a slight edge in throw going to the BTU and slight edge in lumens and maybe flood going to the Fenix.

Both lights are equal in output or throw to human eyes though in calculation BTU is 100m longer because BTU copy TK70 reflector (credit goes to Fenix). But what about flood? From beamshots, I clearly can see the difference that TK75 is better because flood is about angle of beam profiles. It is not something far away like throw. Again, a flashlight is not just about throw and flood. Let’s not forget a lot of things on BTU are sub standard and don’t deserve current price.

Well, BTU brand start as copycat with a lot disappointments. I have not much high hope on this brand. Ultrafire copy either, at least they sell it at much lower price. Just look at UF-T50 and Zebralight, Ultrafire is 2-3 times cheaper. Why? Because they know they save a lot on R&D and they are not greedy. BTU also spend a lot less on R&D as it copy TK70. If TK70 is selling at $180, can BTU sell at $90 or lower, definitely can as all these high end flashlights have 100% gross margin as they can’t sell as many as low end flashlights. I am still alarmed to see some of you defending BTU when you pay $150 for BTU where it is stated to be 3500 Lumens and AR lens. Well, maybe some of you really “LOVE” BTU. But that doesn’t mean you should spread around wrong information about BTU saying how good it is and hiding all the “cheatings” it has.

Those BTU lover attacking me or TK75, you need to reconsider your BTU throw is effort of Fenix. Be grateful when you enjoy throw of BTU. I don’t attack you all, I am just stating facts about BTU.

And I don’t work for Fenix. I once insisted TN31 out throw TK70 when ILIKEFLASHLIGHTS posted a lot beamshots about TK70 and TN31.

But I have watched you attack RDR everytime he comes in and posts his field stats. I don’t see the BTU as a ‘copy cat’ . At the time it was introduced. It was filling the void in the industry for a smaller heavy duty thrower/ flooder. If you remember, the TK75 was introduced after the BTU had been in production. Your blantant disregard for actual field stats is disconcerting. Even owners of the TK75 admit what a good lite the BTU is. You insist the BTU is sub standard. Yet you don’t own one. You aren’t fair & unbiased in your assesment. Many light companies rely on each others designs. Look at the SST-90’s. There are a finite amount of design variations. Just because one uses similiar technology doesn’t make it a copy cat. I think many of the so called ‘cutting corners’ you refer to. Was BTU’s effort to lighten a already hefty design.

I certainly am not trying to attack you. I’m just baffled why you have such a passion for hating the BTU. And most, including me, readily admit the TK75 is an awesome light. I have used both lights many times and I know BOTH lights are awesome. Both have advantages and disadvantages. And I have no issue if somebody picks the TK75 over the BTU, after all its a great light with features some prefer.
But what’s with the hatred and false claims against the BTU? A light that you have no personal experience with. It is a very good light with an unmatched throw and flood combo. No LED flashlight on the market can beat it. Now that is a fact.
And are you seriously trying to claim the BTU doesn’t have much flood? That’s a joke. The BTU has TONS of flood. Does it start as soon as a King or TK75 - of course not since it has the deeper reflectors with tighter angles. But I can assure you the BTU will illuminate a HUGE area of light for hundreds of meters.
Now if you don’t like this light, that fine. But why do you feel it’s your primary duty in life to wrongly trash it? You can see most actual owners of this light like it. Some have issue and have stated it. Some are just as impressed as me. But in either case we are justified in our claims good or bad since we have actually used the light.
I have never stated any false info on this light. I don’t guess what my lights do, I test them and find out the facts. Facts like when I openly admitted the TK75 edged out the BTU by 45 lumens. If I was trying to falsely promote this light I would have simply lied and said the BTU kicked its butt. But I didn’t. I have stated my opinion multiple times, such as I like the “heft” of the BTU, and I don’t like the two button function of the TK75. Those are just opinions and everybody has the right to their own. Just like I also think a side clicky on the BTU would be nice and a AR lens would be a good addition.
And if I actually thought another test on this light would actually allow you to make an better decision on the BTU, I would do it. But I know anything I post, show, or demonstrate for you will never be enough. You are so blinded by your hatred for it that nothing else matters. Just like everything I just wrote in this post is pointless since you will likely dispute everything I just stated.
Ok, now your turn to trash the BTU again.
