Nice pictures. That does a great job of showing just how massive the TK70 really is.
My avatar also has a lustefire triple you can see how much smaller it is compared with the BTU Shocker. The Shocker is in the middle the Lustefire is on the top left. The other two on the top are J-19's and on the bottom is a SP03 and a king.
I posted an overview here. I have not posted anything about the mod yet..Im currently using it in direct drive and XM-L2 U2s on copper. 18 AWG wires and resistance mods.. I started with 3 de-domed. But I swapped one out with a domed emitter.
I just call it a TK-70 clone because I have seen others do it before me. People know better what light it is then.. I know its smaller. The original TK-70 is roughly the same size as a Led-Lenser X21R, which is huge!
In terms of output/beam my modified Lustefire 3XU2 beats the X21R in every compartment. Except when its raining/or fog. Then the concentrated beam from the X21R is better. Me and a friend did some side by side testing last weekend. :)
As far as I have seen a X21R is better or pretty equal to the TK70 when it comes to throw.
The Lustefire, the Tangsfire the... xxxfire with the same body style. They all have different names. I think people just call them TK-70 clone because in terms of looks/head design it reminds people of a TK-70.
Nice to see them side by side. Thanks for sharing. :)
Stock it goes from the BTU to the Lustefire then the SP03 (pretty close those two) then the J-19.
What I like best about the lustefire is it’s flood. It has a very nice beam profile. I haven’t tried it with de-domed led’s yet because of that and because I have the others. I put XM-L2’s on copper, a dry driver and heavy gauge wire and with that in it beats the stock BTU in flood and is about the same in throw.
Modded the BTU is a still number one overall closely followed by the J-19.
The J-19 is a dog stock, it just has the original trustfire 3T6 driver.
Modded With de-domed XM-L2’s on copper and a dry driver the J-19 is my favorite of the bunch. One of my J-19’s out throws my modded BTU but it has XP-G2’s in it so it’s not as floody. The J-19 is much better to carry than the BTU and longer run time. It’s slightly heavier than the BTU but not so top heavy.
I haven’t modded the SP03 because of the glued in driver. Plus it’s pretty nice having the run time it does. It’s a nice light for long walks because of it’s size and run time. Although I have a modded Mystery Sky Ray triple that has about the same throw and a lot more flood and it’s smaller yet. I actually use it more than any of my lights.
Unfortunately I didn’t take any reading on them stock.
