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. :)
